1. Sugary Foods
No surprise here. Diabetes is a condition in which your body’s insulin becomes overwhelmed by the sugar in your bloodstream and can no longer process it into energy. Diabetics and prediabetics alike must be careful about eating sugar to avoid dangerous spikes in blood glucose levels. That means eschewing things that have a ton of sugar but no redeeming nutritional value, like candy, soda, and baked desserts.
However, our bodies truly need sugar to fuel all life processes, so you don’t need to avoid it all together. The important thing is to enjoy your sweet treats mostly in the form of fruit. Fruit contains fiber along with sugar, which can moderate the rate at which the sugar hits your blood stream. If you have a high-protein snack along with your fruit, you will make even better use of that sugar.
