Your Colon and Stool
Very informative. Remember to "check" your poop when doing your daily "big business"!
Examining your poop is one of the best ways to find out what's really going on in your body. So take this quick quiz to get the inside scoop on your poop!
Question #1: How long does it take you to have a bowel movement?
[ ]Less than 60 seconds [ ]More than two minutes
Answer: Healthy bowel movements happen within 60 seconds of sitting on the toilet. The stool should easily come out without straining, grunting or any discomfort. It should have the consistency of toothpaste. If you have time to read a newspaper while sitting on the toilet—you probably have a problem with constipation or poor bowel health.
Question #2: What is the shape of your stool?
[ ]Long like a banana [ ]round, hard pellets [ ]thin, pencil-shaped
Answer: Healthy stool averages about four to six inches long and are shaped like a banana or a torpedo. Very narrow, pencil-shaped stool is a sign your colon walls are impacted or you have polyps or growths on the inside of your colon or rectum. This causes the stool to squeeze to get through. Stress can also create narrow stool.
Hard, round or pellet-shaped stool is a possible sign of poor liver function, lack of exercise, dehydration or constipation.
Question #3: Is your stool accompanied by foul odor?
[ ]Yes [ ]No
Answer: Gas or odor is a sign of a bacterial imbalance in your intestinal flora. The "bad" bacteria release foul-smelling gases and toxins that can cramp your colon and create embarrassing odors. You can eliminate this odor by removing debris and encrusted feces from the walls of your intestines and restoring the balance in your intestinal flora.
Question #4: What color is your stool?
[ ]Yellow [ ]Green [ ]Brown [ ]Gray [ ]Black [ ]Bright red
According to Mayo Clinic research, all shades of brown and even green are considered normal stool colors. And the foods you eat can affect the color of your stool. For example, beets, tomato juice, blueberries, popsicles and green leafy vegetables can affect your stool color. However, a distinct change in stool color can be a warning sign for health problems.
Yellow-colored stool indicates your food is moving too quickly through your digestive tract—as in the case of diarrhea. If stool is greasy or foul-smelling, it may indicate excess fat caused by mal-absorption of nutrients.
Green-colored stool means your food isn't properly being processed through your intestines. As a result, bile isn't broken down—and gives your stool that green color. Green stool can also mean you're eating too much sugar, fruits and vegetables and not enough grains or salt.
Gray or ashy colored stool indicates undigested fats or heavy use of prescription or over-the-counter drugs that contain aluminum hydroxide. It can also indicate a lack of bile in the stool that may be caused by a bile duct obstruction.
Black stool is a serious warning sign for bleeding in the upper gastrointestinal tract—possibly the stomach.
Bright red stool may indicate bleeding in the lower intestinal tract—possibly the large intestine or rectum. Hemorrhoids may also be the source of the bleeding.
Question #5: Do you pass gas while you're having a bowel movement or have you noticed air or bubbles in your stool?
[ ]Yes [ ]No
Answer: Air or bubbles in stool can indicate an intestinal imbalance. Gas producing bacteria may be overgrowing and competing with the healthier flora in your gut.
Please know this: A normal bowel movement happens within 60 seconds of sitting on the toilet.
There should be no straining, pain, bleeding or foul odor accompanied with your bowel movements.
And wiping afterward should be easy and simple—using just one or two pieces of toilet paper!
If that's not your experience in the bathroom—then you need to give your intestines a thorough internal cleaning!
When your colon is in danger—it will do anything and everything to send out an S.O.S. for health!
If you notice strong body odor—especially under your arm pits......Or if your friends shy away and frequently offer you breath mints—LISTEN to your colon—it's screaming for help!
And INTESTINAL parasites can also trigger:
· Painful gas and bloating
· Irritable bowels
· Runny stool or diarrhea
· Allergies
· Skin outbreaks
· Insomnia
· Poor immune system
· Muscle pain and joint soreness
· And much more!

Cleaning Your Kidneys
Is this true? I I have no idea but I don't see any harm in giving it a try.
Years pass by and our kidneys are filtering the blood by removing salt, poison and any unwanted entering our body. With time, the salt accumulates and this needs to undergo cleaning treatments.
How are we going to do this? It is very easy:
1. First take a bunch of parsley and wash it clean
2. Then cut it in small pieces and put it in a pot
3. Pour clean water and boil it for ten minutes
4. Let it cool down, then filter it and pour into a clean bottle
5. Keep it inside refrigerator to cool
Drink one glass daily and you will notice all salt and other accumulated poison coming out of your kidney by urination.
Also you will be able to notice the difference which you never felt before.
Parsley is known as best cleaning treatment for kidneys and it is natural!

25 Ridiculously Healthy Foods
Prevention.com
The following power foods can claim big bragging rights: They can fend off serious diseases like diabetes and cancer and heart problems; fortify your immune system; protect and smooth your skin; and help you lose weight or stay slim.
If you're eating most of them already, good for you! If not, now's the time to load up your shopping cart and supercharge your health!
1. Eggs
Egg yolks are home to tons of essential but hard-to-get nutrients, including choline, which is linked to lower rates of breast cancer (one yolk supplies 25% of your daily need) and antioxidants that may help prevent macular degeneration and cataracts. Though many of us have shunned whole eggs because of their link to heart disease risk, there’s actually substantial evidence that for most of us, eggs are not harmful but healthy.
People with heart disease should limit egg yolks to two a week, but the rest of us can have one whole egg daily; research shows it won’t raise your risk of heart attack or stroke. Make omelets with one whole egg and two whites, and watch cholesterol at other meals.
2. Greek Yogurt
Yogurt is a great way to get calcium, and it’s also rich in immune-boosting bacteria. But next time you hit the yogurt aisle, pick up the Greek kind—compared with regular yogurt, it has twice the protein (and 25% of women over 40 don’t get enough). Look for fat-free varieties like Oikos Organic Greek Yogurt (90 calories and 15 g of protein per 5.3-ounce serving).
3. Fat-Free Milk
Yes, it does a body good: Studies show that calcium isn’t just a bone booster but a fat fighter too. Recent research from the University of Tennessee found that obese people who went on a low-calorie, calcium-rich diet lost 70% more weight than those who ate the least. Vitamin D not only allows your body to absorb calcium, it’s also a super nutrient in its own right. Recent research found that adequate D levels can reduce heart disease risk, ward off certain types of cancer, relieve back pain, and even help prevent depression, but most of us don’t get nearly enough of the 1,000+ IU daily that most experts recommend.
A splash of milk in your morning coffee isn’t enough to provide the calcium and vitamin D you need. Use milk instead of water to make your oatmeal, have a glass with breakfast, or stir some chocolate syrup into it for an after-dinner treat.
4. Salmon
Salmon is a rich source of vitamin D and one of the best sources of omega-3s you can find. These essential fatty acids have a wide range of impressive health benefits—from preventing heart disease to smoothing your skin and aiding weight loss to boosting your mood and minimizing the effects of arthritis. Unfortunately, many Americans aren’t reaping these perks because we’re deficient, which some experts believe may be at the root of many of the big health problems today, like obesity, heart disease, and cancer.
Omega-3s also slow the rate of digestion, which makes you feel fuller longer, so you eat fewer calories throughout the day.
5. Lean Beef
Lean beef is one of the best-absorbed sources of iron there is. (Too-little iron can cause anemia.) Adding as little as 1 ounce of beef per day can make a big difference in the body’s ability to absorb iron from other sources, says Mary J. Kretsch, PhD, a researcher at the USDA-ARS Western Human Nutrition Research Center in Davis, CA. Beef also packs plenty of zinc (even minor deficiencies may impair memory) and B vitamins, which help your body turn food into energy.
If you can, splurge on grass-fed. Compared with grain-fed beef, it has twice the concentration of vitamin E, a powerful brain-boosting antioxidant. It’s also high in omega-3 fatty acids. Because this type of beef tends to be lower in overall fat, it can be tough—so marinate it, and use a meat thermometer to avoid overcooking.
6. Beans
It’s hard to imagine a more perfect food than beans. One cooked cupful can provide as much as 17 g fiber. They're also loaded with protein and dozens of key nutrients, including a few most women fall short on—calcium, potassium, and magnesium. Studies tie beans to a reduced risk of heart disease, type 2 diabetes, high blood pressure, and breast and colon cancers.
The latest dietary guidelines recommend consuming at least 3 cups of beans a week—3 times the measly 1 cup we usually get. Keep your cupboards stocked with all kinds: black, white, kidney, fat-free refried, etc. Use them in salads, stuffed baked potatoes, and veggie chili or pureed for sandwich spreads.
7. Nuts
In a nutshell: USDA researchers say that eating 1½ ounces of tree nuts daily can reduce your risk of heart disease and diabetes. Walnuts are rich in omega-3s. Hazelnuts contain arginine, an amino acid that may lower blood pressure. An ounce of almonds has as many heart-healthy polyphenols as a cup of green tea and 1/2 cup of steamed broccoli combined; they may help lower LDL cholesterol as well.
The key is moderation, since nuts are high in calories. Keep a jar of chopped nuts in your fridge, and sprinkle a tablespoon on cereal, salads, stir-fries, or yogurt. Or have an ounce as a snack most days of the week.
8. Edamame and Tofu
Soy’s days as a cure-all may be over—some claims, such as help for hot flashes, don’t seem to be panning out—but edamame still has an important place on your plate. Foods such as tofu, soy milk, and edamame help fight heart disease when they replace fatty meats and cheeses, slashing saturated fat intake. Soy also contains heart-healthy polyunsaturated fats, a good amount of fiber, and some important vitamins.
Soy’s isoflavones, or plant estrogens, may also help prevent breast cancer. Some researchers believe these bind with estrogen receptors, reducing your exposure to the more powerful effects of your own estrogen, says Prevention advisor Andrew Weil, MD. But stick with whole soy foods rather than processed foods, like patties or chips, made with soy powder. Don’t take soy supplements, which contain high and possibly dangerous amounts of isoflavones.
9. Oatmeal
Fiber-rich oats are even healthier than the FDA thought when it first stamped them with a heart disease–reducing seal 10 years ago. According to new research, they can also cut your risk of type 2 diabetes. When Finnish researchers tracked 4,316 men and women over the course of 10 years, they found that people who ate the highest percentage of cereal fiber were 61% less likely to develop type 2 diabetes.
To reap the benefits, eat 1/2 cup daily—preferably unsweetened. For a versatile breakfast, top with different combinations of fruit, yogurt, and nuts. You can also use oats to coat fish or chicken or add texture to meatballs.
10. Flaxseed
Flaxseed is the most potent plant source of omega-3 fats. Studies indicate that adding flaxseed to your diet can reduce the development of heart disease by 46%—it helps keep red blood cells from clumping together and forming clots that can block arteries. It may also reduce breast cancer odds. In one study, women who ate 10 g of flaxseed (about 1 rounded tablespoon) every day for 2 months had a 25% improvement in the ratio of breast cancer–protective to breast cancer–promoting chemicals in their blood.
Sprinkle 1 to 2 tablespoons of flaxseed a day on your cereal, salad, or yogurt. Buy it preground, and keep it refrigerated.
11. Olive Oil
Olive oil is full of heart-healthy monounsaturated fats (MUFAs), which lower “bad” LDL cholesterol and raise “good” HDL cholesterol. It’s rich in antioxidants, which may help reduce the risk of cancer and other chronic diseases, like Alzheimer’s.
Look for extra virgin oils for the most antioxidants and flavor. Drizzle small amounts on veggies before roasting; use it to sauté or stir-fry, in dressings and marinades, and to flavor bread at dinner in lieu of a layer of butter or margarine.
12. Avocado
These smooth, buttery fruits are a great source of not only MUFAs but other key nutrients as well. One Ohio State University study found that when avocado was added to salads and salsa, it helped increase the absorption of specific carotenoids, plant compounds linked to lower risk of heart disease and macular degeneration, a leading cause of blindness. “Avocados are packed with heart-protective compounds, such as soluble fiber, vitamin E, folate, and potassium,” says Elizabeth Somer, RD, author of 10 Habits That Mess Up a Woman's Diet.
But they are a bit high in calories. To avoid weight gain, use avocado in place of another high-fat food or condiment, such as cheese or mayo.
13. Broccoli
Pick any life-threatening disease—cancer, heart disease, you name it—and eating more broccoli and its cruciferous cousins may help you beat it, Johns Hopkins research suggests. Averaging just four weekly servings of veggies like broccoli, cabbage, and cauliflower slashed the risk of dying from any disease by 26% among 6,100 people studied for 28 years.
For maximum disease-fighting benefits, whip out your old veggie steamer. It turns out that steaming broccoli lightly releases the maximum amount of sulforaphane.
14. Spinach
We’ll spare you the Popeye jokes, but spinach has serious health muscles. For one thing, it contains lots of lutein, the sunshine-yellow pigment found in egg yolks. Aside from guarding against age-related macular degeneration, a leading cause of blindness, lutein may prevent heart attacks by keeping artery walls clear of cholesterol.
Spinach is also rich in iron, which helps deliver oxygen to your cells for energy, and folate, a B vitamin that prevents birth defects. Cook frozen spinach leaves (they provide more iron when cooked than raw) and serve as a side dish with dinner a few times a week.
15. Tomatoes
Tomatoes are our most common source of lycopene, an antioxidant that may protect against heart disease and breast cancer. The only problem with tomatoes is that we generally eat them in the form of sugar-loaded jarred spaghetti sauce or as a thin slice in a sandwich. For a healthier side dish idea, quarter plum tomatoes and coat with olive oil, garlic powder, salt, and pepper. Roast in a 400°F oven for 20 minutes, and serve with chicken.
16. Sweet Potatoes
One of the best ways to get vitamin A—an essential nutrient that protects and maintains eyes, skin, and the linings of our respiratory, urinary, and intestinal tracts—is from foods containing beta-carotene, which your body converts into the vitamin. Beta carotene–rich foods include carrots, squash, kale, and cantaloupe, but sweet potatoes have among the most. A half-cup serving of these sweet spuds delivers only 130 calories but 80% of the DV of vitamin A. Replace tonight’s fries with one medium baked sweet potato (1,096 mcg) and you’re good to go—and then some.
17. Garlic
Garlic is a flavor essential and a health superstar in its own right. The onion relative contains more than 70 active phytochemicals, including allicin, which studies show may decrease high blood pressure by as much as 30 points. High consumption of garlic lowered rates of ovarian, colorectal, and other cancers, according to a research review in the American Journal of Clinical Nutrition. Allicin also fights infection and bacteria. British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; garlic takers were two-thirds less likely to catch a cold.
The key to healthier garlic: Crush the cloves, and let them stand for up to 30 minutes before heating them, which activates and preserves the heart-protecting compounds, according to a 2007 study from Argentina.
18. Red Peppers
Citrus fruits get all the credit for vitamin C, but red peppers are actually the best source. Vitamin C may be best known for skin and immunity benefits. Researchers in the United Kingdom looked at vitamin C intake in 4,025 women and found that those who ate more had less wrinkling and dryness. And although getting enough vitamin C won’t prevent you from catching a cold or flu, studies show that it could help you recover faster.
Vitamin C has other important credentials too. Finnish researchers found that men with low levels were 2.4 times likelier to have a stroke, and Australian scientists recently discovered that the antioxidant reduces knee pain by protecting your knees against arthritis.
19. Figs
When you think of potassium-rich produce, figs probably don’t come to mind, but you may be surprised to learn that six fresh figs have 891 mg of the blood pressure-lowering mineral, nearly 20% of your daily need—and about double what you’d find in one large banana. In a recent 5-year study from the Netherlands, high-potassium diets were linked with lower rates of death from all causes in healthy adults age 55 and older. Figs are one of the best fruit sources of calcium, with nearly as much per serving (six figs) as 1/2 cup of fat-free milk.
Serve by chopping and adding to yogurt, cottage cheese, oatmeal, or green salads. Or enjoy them as a savory snack: Cut a slit in the side and stuff with 1/2 teaspoon of a low-fat version of a soft cheese such as chèvre or Brie.
20. Blueberries
Blueberries may very well be the most potent age-defying food—they’re jam-packed with antioxidants. When researchers at Cornell University tested 25 fruits for these potent compounds, they found that tangy-sweet wild blueberries (which are smaller than their cultivated cousins) packed the most absorbable antioxidants. Research shows a diet rich in blueberries can help with memory loss, prevent urinary tract infections, and relieve eyestrain.
Add up to 1/2 cup of blueberries to your diet a day for maximum health benefits, recommends Ronald Prior, PhD, adjunct professor of food science at the University of Arkansas in Fayetteville. This alone provides just about double the amount of antioxidants most Americans get in 1 day.
21. Asian Pears
One large Asian pear has a whopping 10 g of cholesterol-lowering fiber, about 40% of your daily need. People who ate the most fiber had the lowest total and LDL cholesterol levels, according to a recent study of Baltimore adults. The same researchers found that people who ate the most fiber also weighed the least and had the lowest body mass index and waist circumference.
Serve by dicing it into a salad of Boston lettuce, crumbled goat cheese, walnuts, and mandarin oranges. Or make it a dessert: Add peeled and cored pears to a saucepan with 1 cup white wine, 1 teaspoon honey, 1 teaspoon grated fresh ginger, and enough water to cover the pears. Cover and simmer 40 minutes or until pears are soft.
22. Lychee
A French study published in the Journal of Nutrition found that lychee has the second-highest level of heart-healthy polyphenols of all fruits tested—nearly 15% more than the amount found in grapes (cited by many as polyphenol powerhouses). The compounds may also play an important role in the prevention of degenerative diseases such as cancer.
Serve by peeling or breaking the outer covering just below the stem; use a knife to remove the black pit. Add to stir-fries or skewer onto chicken kebabs to add a sweet, grapelike flavor.
23. Apples
One of the healthiest fruits you should be eating is one you probably already are: the apple. The Iowa Women’s Health Study, which has been investigating the health habits of 34,000 women for nearly 20 years, named apples as one of only three foods (along with pears and red wine) that are most effective at reducing the risk of death from heart disease among postmenopausal women. Other massive studies have found the fruit to lower risk of lung cancer and type 2 diabetes—and even help women lose weight.
In fact, one of the only things that could make an apple unhealthy is mixing it with sugar, flour, and butter and stuffing it into a mile-high pie. Instead, have one as an afternoon snack with a tablespoon of peanut butter, or add slices to sandwiches or salads.
24. Guava
Native to South America, this tropical fruit is an excellent source of skin-healing vitamin C, with 250% of your RDA per serving. One cup of guava has nearly 5 times as much C as a medium orange (377 mg versus 83 mg)—that’s more than 5 times your daily need. It’s also loaded with lycopene (26% more than a tomato), which may help lower your risk of heart disease. And according to research by microbiologists in Bangladesh, guava can even protect against foodborne pathogens such as Listeria and staph.
You can buy guava juice, or simmer chunks in water as you would to make applesauce. Guava also makes a super smoothie: Blend 1/2 banana, 1/2 ripe guava, a handful of strawberries, 1/2 cup soy milk, and a few ice cubes.
25. Dark Chocolate
Thank you, dark chocolate, for making us feel good—not guilty—about dessert. Dark chocolate is filled with flavonoid antioxidants (more than 3 times the amount in milk chocolate) that keep blood platelets from sticking together and may even unclog your arteries.It may also help with weight loss by keeping you feeling full, according to a study from Denmark. Researchers gave 16 participants 100 g of either dark or milk chocolate and 2 hours later offered them pizza. Those who consumed the dark chocolate ate 15% fewer calories than those who had milk chocolate, and they were less interested in fatty, salty, and sugary foods.
Try a chocolate with 70% or more cocoa. Two tablespoons of dark chocolate chips with fresh berries as a mid-afternoon snack or after-dinner dessert should give you some of the heart-healthy benefits without busting your calorie budget.
The following power foods can claim big bragging rights: They can fend off serious diseases like diabetes and cancer and heart problems; fortify your immune system; protect and smooth your skin; and help you lose weight or stay slim.
If you're eating most of them already, good for you! If not, now's the time to load up your shopping cart and supercharge your health!

To reap the benefits, eat 1/2 cup daily—preferably unsweetened. For a versatile breakfast, top with different combinations of fruit, yogurt, and nuts. You can also use oats to coat fish or chicken or add texture to meatballs.
10. Flaxseed
Flaxseed is the most potent plant source of omega-3 fats. Studies indicate that adding flaxseed to your diet can reduce the development of heart disease by 46%—it helps keep red blood cells from clumping together and forming clots that can block arteries. It may also reduce breast cancer odds. In one study, women who ate 10 g of flaxseed (about 1 rounded tablespoon) every day for 2 months had a 25% improvement in the ratio of breast cancer–protective to breast cancer–promoting chemicals in their blood.
Sprinkle 1 to 2 tablespoons of flaxseed a day on your cereal, salad, or yogurt. Buy it preground, and keep it refrigerated.
11. Olive Oil
Olive oil is full of heart-healthy monounsaturated fats (MUFAs), which lower “bad” LDL cholesterol and raise “good” HDL cholesterol. It’s rich in antioxidants, which may help reduce the risk of cancer and other chronic diseases, like Alzheimer’s.
Look for extra virgin oils for the most antioxidants and flavor. Drizzle small amounts on veggies before roasting; use it to sauté or stir-fry, in dressings and marinades, and to flavor bread at dinner in lieu of a layer of butter or margarine.
12. Avocado
These smooth, buttery fruits are a great source of not only MUFAs but other key nutrients as well. One Ohio State University study found that when avocado was added to salads and salsa, it helped increase the absorption of specific carotenoids, plant compounds linked to lower risk of heart disease and macular degeneration, a leading cause of blindness. “Avocados are packed with heart-protective compounds, such as soluble fiber, vitamin E, folate, and potassium,” says Elizabeth Somer, RD, author of 10 Habits That Mess Up a Woman's Diet.
But they are a bit high in calories. To avoid weight gain, use avocado in place of another high-fat food or condiment, such as cheese or mayo.
13. Broccoli
Pick any life-threatening disease—cancer, heart disease, you name it—and eating more broccoli and its cruciferous cousins may help you beat it, Johns Hopkins research suggests. Averaging just four weekly servings of veggies like broccoli, cabbage, and cauliflower slashed the risk of dying from any disease by 26% among 6,100 people studied for 28 years.
For maximum disease-fighting benefits, whip out your old veggie steamer. It turns out that steaming broccoli lightly releases the maximum amount of sulforaphane.
14. Spinach
We’ll spare you the Popeye jokes, but spinach has serious health muscles. For one thing, it contains lots of lutein, the sunshine-yellow pigment found in egg yolks. Aside from guarding against age-related macular degeneration, a leading cause of blindness, lutein may prevent heart attacks by keeping artery walls clear of cholesterol.
Spinach is also rich in iron, which helps deliver oxygen to your cells for energy, and folate, a B vitamin that prevents birth defects. Cook frozen spinach leaves (they provide more iron when cooked than raw) and serve as a side dish with dinner a few times a week.
15. Tomatoes
Tomatoes are our most common source of lycopene, an antioxidant that may protect against heart disease and breast cancer. The only problem with tomatoes is that we generally eat them in the form of sugar-loaded jarred spaghetti sauce or as a thin slice in a sandwich. For a healthier side dish idea, quarter plum tomatoes and coat with olive oil, garlic powder, salt, and pepper. Roast in a 400°F oven for 20 minutes, and serve with chicken.
16. Sweet Potatoes
One of the best ways to get vitamin A—an essential nutrient that protects and maintains eyes, skin, and the linings of our respiratory, urinary, and intestinal tracts—is from foods containing beta-carotene, which your body converts into the vitamin. Beta carotene–rich foods include carrots, squash, kale, and cantaloupe, but sweet potatoes have among the most. A half-cup serving of these sweet spuds delivers only 130 calories but 80% of the DV of vitamin A. Replace tonight’s fries with one medium baked sweet potato (1,096 mcg) and you’re good to go—and then some.
17. Garlic
Garlic is a flavor essential and a health superstar in its own right. The onion relative contains more than 70 active phytochemicals, including allicin, which studies show may decrease high blood pressure by as much as 30 points. High consumption of garlic lowered rates of ovarian, colorectal, and other cancers, according to a research review in the American Journal of Clinical Nutrition. Allicin also fights infection and bacteria. British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; garlic takers were two-thirds less likely to catch a cold.
The key to healthier garlic: Crush the cloves, and let them stand for up to 30 minutes before heating them, which activates and preserves the heart-protecting compounds, according to a 2007 study from Argentina.
18. Red Peppers
Citrus fruits get all the credit for vitamin C, but red peppers are actually the best source. Vitamin C may be best known for skin and immunity benefits. Researchers in the United Kingdom looked at vitamin C intake in 4,025 women and found that those who ate more had less wrinkling and dryness. And although getting enough vitamin C won’t prevent you from catching a cold or flu, studies show that it could help you recover faster.
Vitamin C has other important credentials too. Finnish researchers found that men with low levels were 2.4 times likelier to have a stroke, and Australian scientists recently discovered that the antioxidant reduces knee pain by protecting your knees against arthritis.
19. Figs
When you think of potassium-rich produce, figs probably don’t come to mind, but you may be surprised to learn that six fresh figs have 891 mg of the blood pressure-lowering mineral, nearly 20% of your daily need—and about double what you’d find in one large banana. In a recent 5-year study from the Netherlands, high-potassium diets were linked with lower rates of death from all causes in healthy adults age 55 and older. Figs are one of the best fruit sources of calcium, with nearly as much per serving (six figs) as 1/2 cup of fat-free milk.
Serve by chopping and adding to yogurt, cottage cheese, oatmeal, or green salads. Or enjoy them as a savory snack: Cut a slit in the side and stuff with 1/2 teaspoon of a low-fat version of a soft cheese such as chèvre or Brie.
20. Blueberries
Blueberries may very well be the most potent age-defying food—they’re jam-packed with antioxidants. When researchers at Cornell University tested 25 fruits for these potent compounds, they found that tangy-sweet wild blueberries (which are smaller than their cultivated cousins) packed the most absorbable antioxidants. Research shows a diet rich in blueberries can help with memory loss, prevent urinary tract infections, and relieve eyestrain.
Add up to 1/2 cup of blueberries to your diet a day for maximum health benefits, recommends Ronald Prior, PhD, adjunct professor of food science at the University of Arkansas in Fayetteville. This alone provides just about double the amount of antioxidants most Americans get in 1 day.
21. Asian Pears
One large Asian pear has a whopping 10 g of cholesterol-lowering fiber, about 40% of your daily need. People who ate the most fiber had the lowest total and LDL cholesterol levels, according to a recent study of Baltimore adults. The same researchers found that people who ate the most fiber also weighed the least and had the lowest body mass index and waist circumference.
Serve by dicing it into a salad of Boston lettuce, crumbled goat cheese, walnuts, and mandarin oranges. Or make it a dessert: Add peeled and cored pears to a saucepan with 1 cup white wine, 1 teaspoon honey, 1 teaspoon grated fresh ginger, and enough water to cover the pears. Cover and simmer 40 minutes or until pears are soft.
22. Lychee
A French study published in the Journal of Nutrition found that lychee has the second-highest level of heart-healthy polyphenols of all fruits tested—nearly 15% more than the amount found in grapes (cited by many as polyphenol powerhouses). The compounds may also play an important role in the prevention of degenerative diseases such as cancer.
Serve by peeling or breaking the outer covering just below the stem; use a knife to remove the black pit. Add to stir-fries or skewer onto chicken kebabs to add a sweet, grapelike flavor.
23. Apples
One of the healthiest fruits you should be eating is one you probably already are: the apple. The Iowa Women’s Health Study, which has been investigating the health habits of 34,000 women for nearly 20 years, named apples as one of only three foods (along with pears and red wine) that are most effective at reducing the risk of death from heart disease among postmenopausal women. Other massive studies have found the fruit to lower risk of lung cancer and type 2 diabetes—and even help women lose weight.
In fact, one of the only things that could make an apple unhealthy is mixing it with sugar, flour, and butter and stuffing it into a mile-high pie. Instead, have one as an afternoon snack with a tablespoon of peanut butter, or add slices to sandwiches or salads.
24. Guava
Native to South America, this tropical fruit is an excellent source of skin-healing vitamin C, with 250% of your RDA per serving. One cup of guava has nearly 5 times as much C as a medium orange (377 mg versus 83 mg)—that’s more than 5 times your daily need. It’s also loaded with lycopene (26% more than a tomato), which may help lower your risk of heart disease. And according to research by microbiologists in Bangladesh, guava can even protect against foodborne pathogens such as Listeria and staph.
You can buy guava juice, or simmer chunks in water as you would to make applesauce. Guava also makes a super smoothie: Blend 1/2 banana, 1/2 ripe guava, a handful of strawberries, 1/2 cup soy milk, and a few ice cubes.
25. Dark Chocolate
Thank you, dark chocolate, for making us feel good—not guilty—about dessert. Dark chocolate is filled with flavonoid antioxidants (more than 3 times the amount in milk chocolate) that keep blood platelets from sticking together and may even unclog your arteries.It may also help with weight loss by keeping you feeling full, according to a study from Denmark. Researchers gave 16 participants 100 g of either dark or milk chocolate and 2 hours later offered them pizza. Those who consumed the dark chocolate ate 15% fewer calories than those who had milk chocolate, and they were less interested in fatty, salty, and sugary foods.
Try a chocolate with 70% or more cocoa. Two tablespoons of dark chocolate chips with fresh berries as a mid-afternoon snack or after-dinner dessert should give you some of the heart-healthy benefits without busting your calorie budget.

What Your Nails Say About Your Health
WedMD
Nails and Health: Read the Signs
Did you know your nails can reveal clues to your overall health? A touch of white here, a rosy tinge there, or some rippling or bumps may be a sign of disease in the body. Problems in the liver, lungs, and heart can show up in your nails. Keep reading to learn what secrets your nails might reveal.
Pale Nails
Very pale or white nails are sometimes linked to aging. But they can also be a sign of serious illness, such as:
- Anemia
- Congestive heart failure
- Liver disease
- Malnutrition
White Nails
If the nails are mostly white with darker rims, this can indicate liver problems, such as hepatitis. In this image, you can see the fingers are also jaundiced, another sign of liver trouble.
Yellow Nails
One of the most common causes of yellow nails is a fungal infection. As the infection worsens, the nail bed may retract, and nails may thicken and crumble. In rare cases, yellow nails can indicate a more serious condition such as severe thyroid disease, lung disease, diabetes or psoriasis.
Bluish Nails
Nails with a bluish tint can mean the body isn’t getting enough oxygen. This could indicate an infection in the lungs, such as pneumonia. A slight bluish base may reveal diabetes.
Rippled Nails
If the nail surface is rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis. Discoloration of the nail is common; the skin under the nail can seem reddish-brown. Psoriasis is a skin condition that starts in the nails 10% of the time.
Cracked or Split Nails
Dry, brittle nails that frequently crack or split have been linked to thyroid disease. Cracking or splitting combined with a yellowish hue is more likely due to a fungal infection.
Puffy Nail Fold
If the skin around the nail appears red and puffy, this is known as inflammation of the nail fold. It may be the result of lupus or another connective tissue disorder.
Dark Lines Beneath the Nail
Dark lines beneath the nail should be investigated as soon as possible. They are sometimes caused by melanoma, the most dangerous type of skin cancer.
Gnawed Nails
Biting your nails may be nothing more than an old habit, but in some cases it’s a sign of persistent anxiety that could benefit from treatment. Nail biting or picking has also been linked to obsessive-compulsive disorder. If you can’t stop, it’s worth discussing with your doctor.
Nails Are Only Part of the Puzzle
Though nail changes accompany many conditions, these changes are rarely the first sign. And many nail abnormalities are harmless -- not everyone with white nails has hepatitis. If you’re concerned about the appearance of your nails, see a dermatologist.

The 5 Steps to becoming a successful trader
Read this from some forex forums. Good stuff but author unknown.
Step 1 - Unconscious Incompetence.
This is the first step you take when starting to look into trading. You know that its a good way of making money because you've heard so many things about it and heard of so many millionaires. Unfortunately, just like when you first desire to drive a car you think it will be easy - after all, how hard can it be? Price either moves up or down - what's the big secret to that then – let’s get cracking!
Unfortunately, just as when you first take your place in front of a steering wheel you find very quickly that you haven't got the first clue about what you're trying to do. You take lots of trades and lots of risks. When you enter a trade it turns against you so you reverse and it turns again .. and again, and again.
You may have initial success, and that’s even worse - because it tells your brain that this really is simple and you start to risk more money.
You try to turn around your losses by doubling up every time you trade. Sometimes you'll get away with it but more often than not you will come away scathed and bruised You are totally oblivious to your incompetence at trading.
This step can last for a week or two of trading but the market is usually swift and you move on to the next stage.
Step 2 - Conscious Incompetence
Step two is where you realize that there is more work involved in trading and that you might actually have to work a few things out. You consciously realize that you are an incompetent trader - you don't have the skills or the insight to turn a regular profit.
You now set about buying systems and e-books galore, read websites based everywhere from
You will test out automated systems on Metatrader, you'll play with moving averages, Fibonacci lines, support & resistance, Pivots, Fractals, Divergence, DMI, ADX, and a hundred other things all in the vein hope that your 'magic system' starts today. You'll be a top and bottom picker, trying to find the exact point of reversal with your indicators and you'll find yourself chasing losing trades and even adding to them because you are so sure you are right.
You'll go into the live chat room and see other traders making pips and you want to know why it's not you - you'll ask a million questions, some of which are so dumb that looking back you feel a bit silly. You'll then reach the point where you think all the ones who are calling pips after pips are liars - they can’t be making that amount because you've studied and you don't make that, you know as much as they do and they must be lying. But they're in there day after day and their account just grows whilst yours falls.
You will be like a teenager - the traders that make money will freely give you advice but you're stubborn and think that you know best - you take no notice and overtrade your account even though everyone says you are mad to - but you know better. You'll consider following the calls that others make but even then it won’t work so you try paying for signals from someone else - they don't work for you either.
You might even approach a 'guru' like Rob Booker or someone on a chat board who promises to make you into a trader (usually for a fee of course). Whether the guru is good or not you won’t win because there is no replacement for screen time and you still think you know best.
This step can last ages and ages - in fact in reality talking with other traders as well as personal experience confirms that it can easily last well over a year and more nearer 3 years. This is also the step when you are most likely to give up through sheer frustration.
Around 60% of new traders die out in the first 3 months - they give up and this is good - think about it - if trading was easy we would all be millionaires. Another 20% keep going for a year and then in desperation take risks guaranteed to blow their account which of course it does.
What may surprise you is that of the remaining 20% all of them will last around 3 years - and they will think they are safe in the water - but even at 3 years only a further 5-10% will continue and go on to actually make money consistently.
By the way - they are real figures, not just some I’ve picked out of my head - so when you get to 3 years in the game don’t think its plain sailing from there.
I’ve had many people argue with me about these timescales - funny enough none of them have been trading for more that 3 years - if you think you know better then ask on a board for someone who's been trading 5 years and ask them how long it takes to become fully 100% proficient. Sure I guess there will be exceptions to the rule - but I haven’t met any yet.
Eventually you do begin to come out of this phase. You've probably committed more time and money than you ever thought you would, lost 2 or 3 loaded accounts and all but given up maybe 3 or 4 times but now its in your blood
One day - in a split second moment you will enter stage 3.
Step 3 - The
Towards the end of stage two you begin to realize that it's not the system that is making the difference. You realize that its actually possible to make money with a simple moving average and nothing else IF you can get your head and money management right You start to read books on the psychology of trading and identify with the characters portrayed in those books and finally comes the eureka moment.
The eureka moment causes a new connection to be made in your brain. You suddenly realize that neither you, nor anyone else can accurately predict what the market will do in the next ten seconds, never mind the next 20 minutes.
Because of this revelation you stop taking any notice of what anyone thinks - what this news item will do, and what that event will do to the markets. You become an individual with your own method of trading
You start to work just one system that you mould to your own way of trading, you're starting to get happy and you define your risk threshold.
You start to take every trade that your 'edge' shows has a good probability of winning with. When the trade turns bad you don't get angry or even because you know in your head that as you couldn't possibly predict it, it isn't your fault - as soon as you realize that the trade is bad you close it. The next trade or the one after it or the one after that will have higher odds of success because you know your system works.
You stop looking at trading results from a trade-to-trade perspective and start to look at weekly figures knowing that one bad trade does not make a poor system.
You have realized in an instant that the trading game is about one thing - consistency of your 'edge' and your discipline to take all the trades no matter what as you know the probabilities stack in your favour.
You learn about proper money management and leverage - risk of account etc etc - and this time it actually soaks in and you think back to those who advised the same thing a year ago with a smile. You weren't ready then, but you are now. The eureka moment came the moment that you truly accepted that you cannot predict the market.
Step 4 - Conscious Competence
You are making trades whenever your system tells you to. You take losses just as easily as you take wins. You now let your winners run to their conclusion fully accepting the risk and knowing that your system makes more money than it looses and when you're on a loser you close it swiftly with little pain to your account.
You are now at a point where you break even most of the time - day in day out, you will have weeks where you make 100 pips and weeks where you lose 100 pips - generally you are breaking even and not losing money. You are now conscious of the fact that you are making calls that are generally good and you are getting respect from other traders as you chat the day away. You still have to work at it and think about your trades but as this continues you begin to make more money than you lose consistently.
You'll start the day on a 20 pip win, take a 35 pip loss and have no feelings that you've given those pips back because you know that it will come back again. You will now begin to make consistent pips week in and week out 25 pips one week, 50 the next and so on.
This lasts about 6 months.
Step 5 - Unconscious Competence
Now we’re cooking - just like driving a car, every day you get in your seat and trade - you do everything now on an unconscious level. You are running on autopilot. You start to pick the really big trades and getting 200 pips in a day doesn’t make you any more excited that getting 1 pips.
You see the newbies in the forum shouting 'go dollar go' as if they are urging on a horse to win in the grand national and you see yourself - but many years ago now.
This is trading utopia - you have mastered your emotions and you are now a trader with a rapidly growing account.
You're a star in the trading chat room and people listen to what you say. You recognize yourself in their questions from about two years ago. You pass on your advice but you know most of it is futile because they're teenagers - some of them will get to where you are - some will do it fast and others will be slower - literally dozens and dozens will never get past stage two, but a few will.
Trading is no longer exciting - in fact it's probably boring you to bits - like everything in life when you get good at it or do it for your job - it gets boring - you're doing your job and that's that.
Finally you grow out of the chat rooms and find a few choice people who you converse with about the markets without being influenced at all.
All the time you are honing your methods to extract the maximum profit from the market without increasing risk. Your method of trading doesn’t change - it just gets better - you now have what women call 'intuition'.
You can now say with your head held high "I'm a currency trader" but to be honest you don’t even bother telling anyone - it's a job like any other.
I hope you’ve enjoyed reading this journey into a trader’s mind and that hopefully you’ve identified with some points in here.
Remember that only 5% will actually make it - but the reason for that isn’t ability, its staying power and the ability to change your perceptions and paradigms as new information comes available.
The losers are those who wanted to 'get rich quick' but approached the market and within 6 months put on a pair of blinkers so they couldn’t see the obvious - a kind of "this is the way I see it and that’s that" scenario - refusing to assimilate new information that changes that perception.
I’m happy to tell you that the reason I started trading was because of the 'get rich quick' mindset. Just that now I see it as 'get rich slow'.
If you’re thinking about giving up I have one piece of advice for you ....
Ask yourself the question "how many years would you go to college if you knew for a fact that there was a million dollars a year job at the end of it?
Take care and good trading to you all.

The Truth About Vitamin D
WebMD
The hottest topic in medicine isn't the newest drug or the latest surgical device: It's vitamin D.
What brought the simmering debate to a boil was a 2007 study showing that people taking normal vitamin D supplements were 7% less likely to die than those who didn't take the daily supplements.
A year later, a major study found that when women with low vitamin D levels get breast cancer, they have a much higher chance of dying from their cancer than women with normal vitamin D levels.
That was surprising news. But just as surprising is the fact that many men, women, and children have insufficient blood levels of this important vitamin.
How many? Data suggest many of us don't get the vitamin D we need. For example, a 2007 study of childbearing women in the Northern U.S. found insufficient vitamin D levels in 54% of black women and in 42% of white women.
These findings led the American Academy of Pediatrics to double the recommended amount of vitamin D a child should take -- and have led many doctors to advise their adult patients to up their vitamin D intake.
Vitamin D deficiency has now been linked to breast cancer, colon cancer, prostate cancer, heart disease, depression, weight gain, and other maladies. These studies show that people with higher levels of vitamin D have a lower risk of disease, although they do not definitively prove that lack of vitamin D causes disease -- or that vitamin D supplements would lower risk.
The Vitamin D Council -- a scientist-led group promoting vitamin D deficiency awareness -- suggests vitamin D treatment might be found helpful in treating or preventing autism, autoimmune disease, cancer, chronic pain, depression, diabetes, heart disease, high bloodpressure, flu, neuromuscular diseases, and osteoporosis. However, there have been no definitive clinical trials.
The best known benefit of vitamin D is its role in helping calcium build strong bones. But that's far from the whole story. Vitamin D helps regulate the immune system and the neuromuscular system. Vitamin D also plays major roles in the life cycle of human cells.
Vitamin D is so important that your body makes it by itself -- but only after skin exposure to sufficient sunlight. Dark skin absorbs less sunlight, so people with dark skin do not get as much vitamin D from sun exposure as do light-skinned people.
But this much direct sun exposure might also expose you to potentially dangerous levels of cancer-causing UV radiation. The American Academy of Dermatology recommends against getting vitamin D from unprotected exposure to sunlight. It's probably a better idea to get vitamin D from foods or from supplements.
Everyone agrees that anyone with a 25-OHD level of less than 15 ng/mL or 37.5 nmol/L (depending on the units reported by a lab) needs more vitamin D. The U.S. National Institutes of health notes that 25-OHD levels over 30 ng/mL are optimal, and that there is "insufficient data" to support recommendations for higher levels. The Vitamin D Council considers the ideal 25-OHD level to be between 40 ng/mL and 70 ng/mL.
There are three vitamin D super foods:
Other food sources of vitamin D include:
That's not enough, Boston University vitamin D expert , MD, PhD, tells WebMD. Holick recommends a dose of 1,000 IU a day of vitamin D for both infants and adults -- unless they're getting plenty of safe sun exposure.
In 2008, the American Academy of Pediatrics recommended that breastfed infants receive 400 IU of vitamin D every day until they are weaned. This doubled the AAP's previous recommendation.
The AAP also recommends 400 IU/day of vitamin D for children and teens who drink less than a quart of vitamin D-fortified milk per day.
The Vitamin D Council recommends that healthy adults take 2,000 IU of vitamin D daily -- more if they get little or no sun exposure.
There's evidence that people with a lot of body fat need more vitamin D than lean people.
It's nearly impossible to get too much vitamin D from sunlight or from foods (unless you take way too much cod liver oil). Nearly all vitamin D overdoses come from supplements.
The Institute of Medicine's Food and Nutrition Board's 1997 recommendations -- scheduled for a May 2010 update -- suggest that 2,000 IU per day of vitamin D is safe for adults and that 1,000 IU per day is safe for infants up to 12 months of age.
However, the relatively small doses of vitamin D in daily vitamin pills are not enough to correct serious vitamin D deficiency. A 2009 study suggested that the best regimen for treating vitamin D insufficiency is 50,000 IU of vitamin D3 taken three times a week for six weeks. This time-limited regimen did not result in vitamin D toxicity.
How much vitamin D is too much? That's controversial. According to the National Institutes of Health, the maximum upper limit for vitamin D is 25 micrograms (1,000 IU) for children up to age 12 months and 50 micrograms (2,000 IU) for everyone else.
But some recent studies suggest that healthy adults can tolerate more than 10,000 IU of vitamin D per day. John Jacob Cannell, MD, executive director of The Vitamin D Council, notes that the skin makes 10,000 IU of vitamin D after 30 minutes of full-body sun exposure. He suggests that 10,000 IU of vitamin D is not toxic.
According to the National Institutes of Health, 25-OHD levels that are consistently over 200 ng/mL are "potentially toxic."
However, a clinical study reported in 2008 suggested that vitamin D2 works as well as vitamin D3.
Many supplements contain vitamin D as vitamin D2 or calciferol. It's derived from irradiated fungus. Because this is not the form of vitamin D naturally made by your body, WebMD nutritionist Kathleen M. Zelman, MPH, RD, recommends using the D3 form for those taking vitamin D supplements.
Because of its potency, different forms of vitamin D are used in prescription medications. If you have a prescription for one of these medications, do not switch to another form of vitamin D without checking with your doctor.
The weight loss drug orlistat -- brand names include Xenical and Alli -- may cut absorption of vitamin D. So does the cholesterol-lowering drug cholestyramine (sold as Questran, LoCholest, and Prevalite). People taking these drugs should discuss vitamin intake with their doctors.
The seizure drugs Phenobarbital and Dilantin (phenytoin), affect vitamin D metabolism and affect calcium absorption. So do anti-tuberculosis drugs.
On the other hand, cholesterol-lowering statin drugs and thiazide diuretics increase vitamin D levels.
The hottest topic in medicine isn't the newest drug or the latest surgical device: It's vitamin D.
What brought the simmering debate to a boil was a 2007 study showing that people taking normal vitamin D supplements were 7% less likely to die than those who didn't take the daily supplements.
A year later, a major study found that when women with low vitamin D levels get breast cancer, they have a much higher chance of dying from their cancer than women with normal vitamin D levels.
That was surprising news. But just as surprising is the fact that many men, women, and children have insufficient blood levels of this important vitamin.
How many? Data suggest many of us don't get the vitamin D we need. For example, a 2007 study of childbearing women in the Northern U.S. found insufficient vitamin D levels in 54% of black women and in 42% of white women.
These findings led the American Academy of Pediatrics to double the recommended amount of vitamin D a child should take -- and have led many doctors to advise their adult patients to up their vitamin D intake.
Why do I need vitamin D?
Your body must have vitamin D to absorb calcium and promote bone growth. Too little vitamin D results in soft bones in children (rickets) and fragile, misshapen bones in adults (osteomalacia). You also need vitamin D for other important body functions.Vitamin D deficiency has now been linked to breast cancer, colon cancer, prostate cancer, heart disease, depression, weight gain, and other maladies. These studies show that people with higher levels of vitamin D have a lower risk of disease, although they do not definitively prove that lack of vitamin D causes disease -- or that vitamin D supplements would lower risk.
The Vitamin D Council -- a scientist-led group promoting vitamin D deficiency awareness -- suggests vitamin D treatment might be found helpful in treating or preventing autism, autoimmune disease, cancer, chronic pain, depression, diabetes, heart disease, high bloodpressure, flu, neuromuscular diseases, and osteoporosis.

Vitamin D is so important that your body makes it by itself -- but only after skin exposure to sufficient sunlight. Dark skin absorbs less sunlight, so people with dark skin do not get as much vitamin D from sun exposure as do light-skinned people.
How can I get enough vitamin D?
Thirty minutes of sun exposure to the face, legs, or back -- without sunscreen -- at least twice a week should give you plenty of vitamin D.But this much direct sun exposure might also expose you to potentially dangerous levels of cancer-causing UV radiation. The American Academy of Dermatology recommends against getting vitamin D from unprotected exposure to sunlight. It's probably a better idea to get vitamin D from foods or from supplements.
Will a vitamin D test tell me if I need more vitamin D?
Yes. As part of your regular blood test, your doctor should order a test for 25-hydroxyvitamin D (25-OHD).Everyone agrees that anyone with a 25-OHD level of less than 15 ng/mL or 37.5 nmol/L (depending on the units reported by a lab) needs more vitamin D. The U.S. National Institutes of health notes that 25-OHD levels over 30 ng/mL are optimal, and that there is "insufficient data" to support recommendations for higher levels. The Vitamin D Council considers the ideal 25-OHD level to be between 40 ng/mL and 70 ng/mL.
Which foods contain vitamin D?
Surprisingly few foods contain vitamin D -- unless it's added to the food. That's because your body is built to get vitamin D through your skin (from sunlight) rather than through your mouth (by food). But once your body has enough, it doesn't matter whether you got it through your skin or through your stomach.There are three vitamin D super foods:
- Salmon (especially wild-caught)
- Mackerel (especially wild-caught; eat up to 12 ounces a week of a variety of fish and shellfish that are low in mercury)
- Mushrooms exposed to ultraviolet light to increase vitamin D
Other food sources of vitamin D include:
- Cod liver oil (warning: cod liver oil is rich in vitamin A; too much may be bad for you)
- Tuna canned in water
- Sardines canned in oil
- Milk or yogurt -- regardless of whether it's whole, nonfat, or reduced fat -- fortified with vitamin D
- Beef or calf liver
- Egg yolks
- Cheese
How much vitamin D do I need?
The current recommended daily dose of vitamin D is 200 IU for people up to age 50, 400 IU for people aged 51 to 70, and 600 IU for people over age 70.That's not enough, Boston University vitamin D expert , MD, PhD, tells WebMD. Holick recommends a dose of 1,000 IU a day of vitamin D for both infants and adults -- unless they're getting plenty of safe sun exposure.
In 2008, the American Academy of Pediatrics recommended that breastfed infants receive 400 IU of vitamin D every day until they are weaned. This doubled the AAP's previous recommendation.
The AAP also recommends 400 IU/day of vitamin D for children and teens who drink less than a quart of vitamin D-fortified milk per day.
The Vitamin D Council recommends that healthy adults take 2,000 IU of vitamin D daily -- more if they get little or no sun exposure.
There's evidence that people with a lot of body fat need more vitamin D than lean people.
Can I get too much vitamin D?
Too much of any good thing is a bad thing. Too much vitamin D can cause an abnormally high blood calcium level, which could result in nausea, constipation, confusion, abnormal heart rhythm, and even kidney stones.It's nearly impossible to get too much vitamin D from sunlight or from foods (unless you take way too much cod liver oil). Nearly all vitamin D overdoses come from supplements.
The Institute of Medicine's Food and Nutrition Board's 1997 recommendations -- scheduled for a May 2010 update -- suggest that 2,000 IU per day of vitamin D is safe for adults and that 1,000 IU per day is safe for infants up to 12 months of age.
However, the relatively small doses of vitamin D in daily vitamin pills are not enough to correct serious vitamin D deficiency. A 2009 study suggested that the best regimen for treating vitamin D insufficiency is 50,000 IU of vitamin D3 taken three times a week for six weeks. This time-limited regimen did not result in vitamin D toxicity.
How much vitamin D is too much? That's controversial. According to the National Institutes of Health, the maximum upper limit for vitamin D is 25 micrograms (1,000 IU) for children up to age 12 months and 50 micrograms (2,000 IU) for everyone else.
But some recent studies suggest that healthy adults can tolerate more than 10,000 IU of vitamin D per day. John Jacob Cannell, MD, executive director of The Vitamin D Council, notes that the skin makes 10,000 IU of vitamin D after 30 minutes of full-body sun exposure. He suggests that 10,000 IU of vitamin D is not toxic.
According to the National Institutes of Health, 25-OHD levels that are consistently over 200 ng/mL are "potentially toxic."
What kind of vitamin D is best?
The recommended form of vitamin D is vitamin D3 or cholecalciferol. This is the natural form of vitamin D that your body makes from sunlight. Supplements are made from the fat of lambs' wool.However, a clinical study reported in 2008 suggested that vitamin D2 works as well as vitamin D3.
Many supplements contain vitamin D as vitamin D2 or calciferol. It's derived from irradiated fungus. Because this is not the form of vitamin D naturally made by your body, WebMD nutritionist Kathleen M. Zelman, MPH, RD, recommends using the D3 form for those taking vitamin D supplements.
Because of its potency, different forms of vitamin D are used in prescription medications. If you have a prescription for one of these medications, do not switch to another form of vitamin D without checking with your doctor.
Does vitamin D interact with other medications?
Yes. Steroid medications such as prednisone can interfere with vitamin D metabolism. If you take steroid drugs regularly, discuss vitamin D with your doctor.The weight loss drug orlistat -- brand names include Xenical and Alli -- may cut absorption of vitamin D. So does the cholesterol-lowering drug cholestyramine (sold as Questran, LoCholest, and Prevalite). People taking these drugs should discuss vitamin intake with their doctors.
The seizure drugs Phenobarbital and Dilantin (phenytoin), affect vitamin D metabolism and affect calcium absorption. So do anti-tuberculosis drugs.
On the other hand, cholesterol-lowering statin drugs and thiazide diuretics increase vitamin D levels.
