Do You Need 8 Glasses of Water a Day?

You need to drink at least 8 glasses of water a day-RIGHT? This has been the prevailing wisdom for years, but does it still hold today?

You need to drink at least 8 glasses of water a day-wait a minute, REALLY? What's come to be accepted wisdom isn't necessarily so. The seemingly universal advice, that drinking 8 glasses of water a day is crucial for optimal bodily function, is more myth than fact. A recent study, conducted at Dartmouth Medical School, found no evidence to support this popular exhortation-extolled by the media, health writers, nutritionists and many doctors. So what's the genesis of this myth? This idea may have gotten its start when the Food and Nutrition Board of the National Research Council, recommended approximately "1 milliliter of water for each calorie of food." This amounts to roughly 2 to 2 quarts per day, or 64 to 80 ounces. But in the next sentence, the Board stated that: "most of this quantity is contained in prepared foods." Apparently, this last sentence seems to have been missed, and that recommendation was erroneously interpreted as how much water one should drink daily.More »

Chewing gum stays in your stomach for 7 years, myth or fact? If you don’t know the answer, watch this to find out.

Your mom told you a million times not to do it. You did it anyway. Did it really sit in your stomach for seven years? Could it have wrapped around your intestines and strangled them? What really happens if you swallow your gum? We've all heard the old wives' tale warning of such disaster, but to our knowledge there's been no serious health issues related to swallowing gum. Although choking on gum is another matter entirely. Though your stomach can't break down a piece of gum the same way it breaks down food, your digestive system can move it along through normal intestinal activity; in other words, it comes out the "other" end. Although chewing gum is designed to be chewed, and not swallowed, it isn't harmful if ingested. And it's OK to swallow the occasional watermelon seed, too, since doctors are pretty sure watermelon seeds do not grow into full-fledged watermelons in our bellies.More »

Mass media, like CNN and Fox, like to hype up tryptophan-rich turkey as the culprit for post-holiday meal sleepiness... but that's just a catchy sound-bite.. NOT reality. The tryptophan is NOT to blame for the sudden drowsiness that hits right after the meal. Turkey DOES contain tryptophan, and scientific evidence supports a connection between this amino acid and sleep. BUT, chicken and ground beef contain almost the same amount of tryptophan as turkey! And L-tryptophan doesn't act on the brain unless you take it on an empty stomach, with no protein present. Tryptophan levels found in a turkey dinner are far too low to have a sleepy effect. It's more likely due to the combination of drinking alcohol AND overeating-not just turkey, but also mashed potatoes, cranberries, yams, stuffing, and pie - all of which pull blood away from your brain to help your digestive system do it's work. It's not the turkey's fault, unless you ate the whole bird by yourself!More »

Does grapefruit burn calories? There are quite a few rumors about this. Watch our featured video and find out if grapefruits can really help with weight loss.

Grapefruit may be a good weight loss food, but it doesn't magically burn calories! The American Dietetic Association states that "...digestion of any food uses a small amount of energy. But no food-or food component-can 'burn up' the calories in food or 'melt away' body fat.'" Low in calories and sodium, grapefruit is high in potassium and water content; all of which can benefit weight loss. The low calorie count in grapefruit means we can eat grapefruit freely without guilt. Eating any fruit with high water content and potassium boosts water ingestion and helps make one feel full. Research has shown that increasing water consumption can increase energy and speed metabolism. But don't take that to mean that eating grapefruit is in ANY way a stand in for a balanced diet and exercise regimen, because it's NOT.More »

Good news for all you choc-aholics: Eating chocolate doesn't cause pimples. Dermatologists agree that acne is NOT caused by any specific food, and YES, this includes French fries, potato chips, candy, and soda! Acne is caused by a buildup of dead skin cells within the pore, an excess of skin oil, and a proliferation of acne-causing bacteria. And NONE of these factors are triggered by the foods we eat. Greasy foods, while not great for your health, won't cause oily skin or produce pimples. Hormonal changes within the body have the GREATEST impact on oil production. Oily skin can be hereditary-if your parents have oily skin, you'll probably have it too. So go ahead, and enjoy that piece of chocolate or order of fries-in moderation, of course. Your SKIN will be no worse for it the next day, but your WAISTLINE is another story!More »

Midnight snacks are fun, but do they make you gain weight? Watch this video to learn if eating at night makes you fat.

While eating late at night has been associated with obesity, midnight munching does not CAUSE obesity. A potbelly is the result of too many calories OVERALL, not just the results of late-night snacks. "The time of day a person eats is not as important for overall weight gain as the amount of calories eaten during the day," says a spokesperson for the American Dietetic Association. Late-night eating CAN lead to extra poundage. But it's NOT because of the time of day, it's because eating late at night is likely to involve ALCOHOL and SOCIALIZING...two factors that often lead us to over-eat. And eating in this state tends to be MINDLESS munching, of calorie-rich foods. Whether or not you gain weight is simple: if you take more calories in than you expend, then weight you will gain. It's about how MUCH you eat, not so much about WHEN you eat. Weight gain and eating late...busted!More »

This may have been a rumor started by the tea industry, and one that is eminently de-bunkable: drinking coffee will NOT give you an ulcer. The thinking, until recently, was that excess stomach acid caused ulcers and that coffee contributed to excess stomach acid. While some people may experience heartburn after drinking coffee, there's NO conclusive evidence that coffee makes the stomach produce excess acid. An ulcer is an open sore in the digestive tract. Most ulcers are found in the stomach and top of the small intestine. When stomach acid comes in contact with an ulcer, it can become quite painful. Recent studies have shown that ulcers are actually caused by a certain bacteria, Heliobacter pylori, and that these ulcers can actually be easily cured with antibiotics. An important distinction to make, however, is that while coffee or spicy foods don't CAUSE ulcers, they may serve to aggravate existing ones.More »

Coffee Stunts Children's Growth: Myth or Fact? Get the truth about how coffee does and doesn't effect children in this health video.

Besides the jitteriness and the insomnia, children have another reason not to drink coffee: it stunts their growth. Or so was once thought, according to an old wives' tale. But after decades of research on the physiological results of coffee consumption, there's no evidence that it has ANY effect on height. The genesis of this myth is unclear. Caffeine consumption was thought to be a factor in osteoporosis, which stemmed from early studies associating high intake of caffeinated beverages with reduced bone mass. Much of the research, however, that linked caffeine and osteoporosis, was conducted in populations that ALSO had low calcium intakes, a DEFINITE culprit of reduced bone health. The minor effect that caffeine MAY have on calcium absorption is easily mitigated by adding a few tablespoons of milk into your coffee. If coffee doesn't stunt children's growth, should you still limit their consumption? Perhaps, if you don't want caffeine-induced mania driving you mildly insane!More »

Colds aren't fun. Neither are sinus infections. So, does this mean that a grilled cheese sandwich will make your stuffed nose even more clogged? Not exactly. It was once thought that milk and other dairy products CAUSED phlegm. But, we know better now! Milk does NOT CAUSE phlegm. But It DOES thicken mucus that's already present. The fat content in dairy products can make mucus feel more "sticky," which has the effect of making a person feel even more congested. For most people with respiratory issues, doctors will advise refraining from dairy if there's an active infection in the lungs or airways, since thicker mucus makes breathing more difficult and can aggravate a cough. You've herd it before, and yes, it's true: drinking plenty of water is your BEST bet thinning the mucus so that it can move more easily out of your system.More »

They're sweet, they're delicious, so they HAVE to be bad for us, right? Wrong. Bananas are ACTUALLY low in fat, in fact: the average banana has just a gram of fat and only 95 calories! And not just that, bananas are ALSO incredibly nutritious. You probably already know that they're high in potassium-which regulates blood pressure and can help ease PMS symptoms. But bananas are ALSO high in vitamin B6-essential for building nerves and immune cells, Vitamin C-which helps build immunity, and fiber-which helps control cholesterol and aids digestive health. The high fiber in a banana ALSO makes you feel full, making it an ideal diet-friendly snack. Another banana benefit? They come in their own convenient packaging, which makes them a handy snack! So great news for banana lovers all over the world-go ahead and enjoy this healthy low-fat fruit 'guilt free' as part of a well balanced diet!More »

More than ten years ago, the Harvard University Nurses' Health Study, which had more than 120,000 subjects, found that consumption of milk and other dairy products DOESN'T actually protect against the bone fractures of osteoporosis. In fact, those in the Harvard study who drank 3 or more servings of milk a day ACTUALLY had a slightly HIGHER rate of fractures than women who drank little or no milk. And it's interesting to note that societies with the highest intakes of dairy-the USA, England, Israel, Finland, and Sweden-ALSO show the HIGHEST rates of osteoporosis. While milk is a good source of calcium, green leafy vegetables, like spinach and collard greens are MORE POTENT sources. And beans, nuts, grains, and cruciferous veggies like brocolli and brussel sprouts, have plenty of calcium too! So don't get get sucked into the milk myth, get your calcium in the vegetable section of your market!More »

Plenty of people wonder, do vegetarians get enough protein? Yes, in fact vegetarians get more protein than the recommended dosage. Learn more about this in the video.

This is simply NOT true. In fact, not only do most Americans consume up to TWICE their daily protein needs, the average vegetarian typically consumes about 1 times MORE than is recommended. Also, the complex combining of foods vegetarians used to do, like rice and beans, for example, to create a "complete" protein, is now considered UNNECESSARY. Just eat a variety of foods and you should be fine. Plant foods offer ABUNDANT protein. Vegetables are around 23% protein on average; beans and other legumes 28%; grains 13%; and even fruit has 5.5%. For comparison, human breast milk is ONLY 5% protein, and is designed for the time in our lives when our protein needs are as HIGH as they'll ever be. Diseases caused by EXCESS protein consumption, like cancer of the breast, colon, prostate, pancreas; osteoporosis and kidney stones are widespread in the USA. Since meat is excessively high in protein, it might be smart to reduce intake from animal sources for protein-rich plant foods.More »
