I have heard about something called glycemic index. Can I tell what the glycemic index is by reading a food label?
You will not be able to gather the glycemic index value from reading the nutrition information label on a food package because it is not listed. The reason being that the glycemic index can vary based on how much processing has occurred to the carbohydrate in the food product. Cooking methods can influence the number as well. For instance, overcooked pasta has a higher glycemic index than firm or al dente. Fruits too can fluctuate based on how under ripe or over ripe they are. If you replace processed and refined carbohydrates, like sweets, fruit juices, white bread and white rice with whole grains, whole produce, nonstarchy vegetables and dried beans, then you are eating more in line with lower glycemic index, which is healthier.
