Following a diet that's low on the glycemic index may help lower your risk for chronic diseases, including diabetes and heart disease, according to a study published in "The American Journal of Clinical Nutrition" in March 2008. This type of diet can also help diabetics control their blood sugar levels, especially if they use it in conjunction with counting carbohydrates.
The glycemic index estimates the effect a particular food will have on your blood sugar level. Nonstarchy vegetables, such as artichokes, tend to be very low in carbohydrates and have minimal effects on blood sugar, making them low-glycemic-index foods. This is due to their high fiber and water content. Most nonstarchy vegetables have a GI of 0, with the exception of a few vegetables, such as carrots, that have a higher carbohydrate count.
