fiber is the only carbohydrate that our bodies don’t break down—the more fiber in the food, the flatter the glucose curve after eating it.

Here’s how to do it: find the number next to Total Carbohydrate and divide it by five. Try to find a food that has that amount of Dietary Fiber (or as close to it as possible).
