    This is not a scientific lesson. First of all, starch (included in their list of “sugars”) is not sugar. Second, humans are hard-wired (i.e., we evolved) to seek/consume sweet foods, such as fruits/berries, because they provide nutrients and an energy source that we need. We have known this for a long time. What is the news here? Third, dopamine also is released when we exercise. Does that make exercise bad? Saying, “too much sugar is bad” is obvious… same as with anything in excess, but it is more than a factual leap to say sugar is bad per se. As is becoming more common, this is just another guilt-by-association of a food component that does not kill anyone who knows how to eat sensibly. Plenty of people eat lots of sweet foods (along with fiber, protein and fats to balance it out) but don’t gain weight or become sugar-addicted zombies. Maybe there should be more focus on making healthier sweet foods — by using more whole grains, fruits, nuts, etc. in the recipe. In fact, these foods already exist.
