Diabetic Diet

Diabetic Diet

  • Diabetes is a strong independent risk factor for cardiovascular disease (CVD), and these two conditions often coexist, sharing common modifiable risk factors.1
  • Although carbohydrate restriction for reducing the glycemic load is of paramount importance in the prevention and management of diabetes, a high fiber diet has an equally important role.
  • Recent research indicates that a high dietary fiber consumption can increase insulin sensitivity and thus decreasing the blood sugar.2 High-fiber diets may protect against obesity and CVD by lowering insulin levels.3
  • Increased intake of bran and whole-grains that are high in fiber has been shown to reduce deaths from heart disease in people with diabetes and is highly recommended.4 The benefit is particularly high for viscous soluble fiber. 5
  • Increased consumption of vegetables, whole grains, and soluble and insoluble fiber is associated with improved glucose metabolism in both diabetic and nondiabetic individuals.6 Such a diet is associated with a reduced risk of diabetes.7-9
  • Increased consumption of fruits and vegetables are recommended for people with diabetes and the proscription of fruits (as practiced in many parts of India) for these people cannot be justified.
  • Psyllium (Metamucil) supplementation has been shown to lower A1C concentration and might be beneficial in people with diabetes with or without medications.10
  • Increasing cereal fiber in the diet may be an effective means of reducing the risk of diabetes, a disease that has reached epidemic proportions in Asian Indians.11
