8 Nutrition Myths You Think Are Fact

You make decisions about what to put into your body all the time. Whether it’s what to have for lunch or which drink is going to best quench your thirst, you probably weigh several different factors before coming to a decision.

It also appears that the quality of calories consumed (low versus high glycemic index) is as important a consideration as the total quantity. And genetics only explains about 2.7% variation in people's weight, according to a study in Nature.
