Diabetes outcome is closely tied to the management strategies and resources available in the various regions of the world.  International Diabetes Federation

“A well-balanced, healthy eating plan is the cornerstone of good blood sugar control for all people with diabetes. Whether you are being treated with insulin or tablets, you still need to follow a sensible eating plan.  The so-called "diabetic diet" is not in fact a diet, but rather a healthy eating plan ideal for the whole family. Eating healthily not only helps to control blood sugar levels (thus also delaying the onset of diabetes-related complications), but also helps to maintain body weight and prevent heart disease.  The old saying ‘you are what you eat’ is exactly right. Your blood sugar levels are affected by everything you eat. Wise food choices are the key to a healthy life and prevention of illness.”
