Why measure glycemic responses on food?Updated 3 years ago

Today many of us evaluate the packaged food’s healthiness based on the nutrition facts and the ingredient list. Although they give us an approximation of what might be better, it does not give us evidence of which product is better for each of us. If our goal is to control our body weight, we could limit the daily calories and net carbs (carb less fiber) but we won’t be able to assess the quality of the food's macronutrients. Glycemic responses on food really tell us how the food impacts our bodies and serves as a proxy to evaluate the quality of macronutrients in foods.
