Numerous studies suggest that people with diabetes who consume a diet high in monounsaturated fat have the same level of control over blood sugar levels as those who eat a low-fat diabetic diet. Monounsaturated fat also help keep triglyceride levels in check, reduces LDL cholesterol levels, and increases HDL cholesterol levels.People living with diabetes are also at a high risk of developing heart disease, so the intake of the right kind of fats is imperative.
