Why should I monitor my blood sugar levels after eating?

Dr. Jack Merendino, MD
Endocrinology Diabetes & Metabolism
By logging your meals, you’ll soon discover which are kindest to your blood sugar. You have quite a choice of breakfasts: eggs, cereal, peanut butter and toast, and much more. What they all have in common: the same amount of carbohydrates. Say you pick an oatmeal-based breakfast, and  two hours after eating, your blood sugar is near normal, but a waffle-based breakfast leaves your blood sugar too high. A number of factors influence blood sugar levels, so you can try those breakfasts again. If you get a similar result each time, it means the oatmeal breakfast is a keeper, and from now on you’ll skip the waffles. Pretty soon, you’ll have a great collection of blood-sugar-friendly meals that work for you.
