We are accustomed to hearing, “Eat this, don’t eat that.” Nearly everyone who makes such a pronouncement is convinced that he or she has discovered the one and only diet that will solve the problem of obesity in America and help all of us avoid weight gain.

If only it were that simple! The US still has a high rate of obesity and a growing rate of type 2 diabetes. Is it only because people are undisciplined about their diets, or might there be other explanations?

Watching Out for Blood Sugar Spikes:

We have all been told to avoid sweets and highly processed carbs such as bagels, pizza or bread. That’s because these foods often cause post-meal spikes in blood sugar first, and then insulin.

How Do You React to Specific Foods?

Now, however, Israeli researchers have found that each of us reacts in a unique way to foods. For some, ice cream will cause the sharpest blood sugar spike; for others, the trigger might be mashed potatoes or bananas. The scientists measured blood sugar responses, bacterial flora and other characteristics of 800 people and developed a computer algorithm that predicts blood sugar response more accurately than that prescribed by an experienced dietitian. What are the implications?

    After My husband & I went on a gF diet, I found that I did not want to overeat as much as I did when eating gluten. It was as if bread & bread products were addictive. I still eat sweets & snacks like tortilla & potato chips but in moderation. Most of our food is cooked from scratch so we avoid additives & preservatives. I am not at my target weight but more in control than before.
