We are most concerned about the "ADDED" sugars in our foods. We are not talking about our nutrient packed natural carbohydrates like fruits and vegetables!
Added sugars have additional names like:
High fructose corn syrup
Fruit juice concentrates
1 gram of sugar = 4 calories
If a label says 15 grams of sugar; that equals 60 calories of sugar.
According to the American Heart Association:
Women should have no more than 100 calories of added sugar (6tsp) of sugar per day.
Men should have no more than 150 calories of added sugar (9tsp) per day.
