Eating nutritious, well-balanced meals is an essential part of controlling - and preventing - diabetes. The American Diabetes Association recommends filling one half of your plate with non-starchy veggies such as spinach or broccoli, one quarter with beans or a whole grain like brown rice, and the last quarter with meat or other protein source such as eggs or tofu. Eating foods high in fiber also help regulate blood sugar and can help you shed extra pounds.
