Top 10 nutrition myths

We all have ideas about what's good for us and what isn't -- based on everything from scientist research, to old wives' tales to urban legend. Subsequently, two nutrition experts decided to take on what they saw as the "Top 10 Nutrition Myths" and set the record straight.

Among the commonly held beliefs that get debunked are "eating carbohydrates makes you fat," and, the one I learned in school as if it were a commandment, "drink eight, 8-oz glasses of water per day." The former is only true if you're eating carbs to excess (your body uses them for energy in moderation), and the latter seems to be based on an arbitrary number, as, in fact, you only need to replace the water you're losing through breathing, sweating and excrement, which may or may not total 64-oz per day.

You also might be interested to know that not all alcohol isn't bad for you, vitamin supplements aren't necessary for everyone, and consuming extra protein does nothing to bulk up muscles.
