Glycemic index for 60+ foods

November 16, 2021

Reviewed by Howard E. LeWine, MD

Measuring carbohydrate effects can help glucose management.

The glycemic index is a value assigned to foods based on how quickly and how high those foods cause increases in blood glucose levels. Foods low on the glycemic index (GI) scale tend to release glucose slowly and steadily. Foods high on the glycemic index release glucose rapidly. Low GI foods tend to foster weight loss, while foods high on the GI scale help with energy recovery after exercise, or to offset hypo- (or insufficient) glycemia. Long-distance runners would tend to favor foods high on the glycemic index, while people with pre- or full-blown diabetes would need to concentrate on low GI foods. Why? People with type 1 diabetes can't produce sufficient quantities of insulin and those with type 2 diabetes are resistant to insulin. With both types of diabetes, faster glucose release from high GI foods leads to spikes in blood sugar levels. The slow and steady release of glucose in low-glycemic foods helps maintain good glucose control.

To help you understand how the foods you are eating might impact your blood glucose level, here is an abbreviated chart of the glycemic index for more than 60 common foods. A more complete glycemic index chart can be found in the link below.
