Pre-Diabetes and Prevention

Prevention: Nutrition

Back to Main Page

A well-balanced diet is essential in reducing one’s risk of developing type II diabetes. It is important to eat foods that will help keep one’s weight in check and maintain relatively consistent levels of sugar in the bloodstream.

Glycemic Index (GI)

A glycemic index or GI, measures how a carbohydrate-containing food raises blood glucose (American Diabetes Association). Eating foods with low glycemic indexes prevents large spikes and drops in one’s blood sugar level and also helps curbs appetite which can contribute to weight loss.

Below is a list of 100 foods and their GI obtained from health.harvard.edu

Carbohydrates

The amount of carbohydrate in a food should also be carefully considered as carbohydrates are essentially converted to sugar in the body. One would should limit the amount of carbohydrates eaten daily to a minimum if they are prediabetic. Generally, one should eat foods that are high in fiber, low in fat, unprocessed, and unrefined.

Here is a chart describing foods to avoid and a couple of smarter alternatives to eat instead that can still help get the nutrients the body needs (according to myfoodplate.gov and American Diabetes Association). The important thing to remember is that one doesn’t have to avoid the foods listed entirely, but to eat them less frequently and in smaller portions:
