A plant-based diet can dramatically improve the health of people with diabetes. Diabetes diets typically call for portion control, carbohydrate limits and - for those who are overweight - calorie restrictions. Fortunately, there is another way. Low-fat, plant-based diets are ideal for diabetes and the conditions associated with it, such as heart disease, weight gain, high cholesterol, and high blood pressure. And, they offer the advantage of not requiring any weighing or measuring of portions.
