Your snacks are made from white flour
“Although the glycemic index of foods is a bit controversial, the quality of carbohydrates in the diet matters,” says Massey. Refined carbohydrates (like white bread, pretzels, chips) have been linked in some studies to higher rates of insulin resistance.
Limit processed products made with white flours and added sugars. Instead, focus on healthy snacks that are high in fiber and made with whole grains, like a string cheese stick and a few whole grain crackers, air-popped popcorn, or rice crackers and peanut butter.
