Why One Diet May Not Fit All


Did you ever wonder why certain diets work for some people, but not for others? Science may have just found the answer.

A new study from Israel found that the glycemic index (GI) of a given food may not be a set value — but may rather depend on the person consuming it. In other words, even if we all ate the same meal, how that meal metabolizes may differ from person to person.

GI is a tool used to measure the effects of food on blood sugar levels. Doctors and nutritionists often use GI to develop healthy diets for patients. However, this finding suggests that personalized nutrition may be more beneficial for lowering blood sugar levels than the traditional GI-based method.
