A Better Approach to Diet for Type 2 Diabetes

Diet For Diabetes by Taylor BensonFor years I’ve sent my newly diagnosed and poorly controlled patients with type 2 diabetes to diabetes education classes.  There they are taught many helpful skills, including how to test their blood sugars at home, how to watch for complications of diabetes like foot ulcers and infections, and a big focus is on how to eat to control their blood sugars.  I’m coming to believe that mainstream medicine, and the American Diabetes Association are not taking the best approach to diet to control type 2 diabetes.  The traditional approach is based on limiting simple carbohydrates, spreading out feedings, and essentially trying not to overload the ability of a patient’s pancreas and metabolic system with excess glucose.  This is sometimes helpful, and i certainly have had patients who embrace this approach and do pretty well.  Still, for most of my patients, counting carbohydrates, limiting calories, and using a low simple carbohydrate diet has not led to excellent control of their blood sugars.

Recently, as a part of my own self-education and motivation to maintain my low-fat vegan diet, I listened to a Rich Roll podcast of an interview with Dr. Neal Barnard about managing diabetes with a low fat, vegan, low-glycemic index approach to eating. This approach resonates with me, and appears to lead to vastly improve glycemic control for diabetic patients who embrace the approach.  I believe this is a valid and improved approach over the standard ADA diet approach.  

Here are the basic tenants of how and why this works:T

  • Type 2 Diabetes is a disease caused by insulin resistance.  Cells are unable to accept insulin as a facilitating molecule to allow glucose to enter cells and keep the level of blood sugar in the bloodstream in a normal range.
  • The underlying cellular mechanism of this insulin resistance is that lipids, essentially dietary fat in the bloodstream, clog the insulin receptor site in cell walls, keeping insulin from being able to attach to the cell walls and open the cell membrane to allow glucose to enter cells.
  • By eating a very low fat diet and completely avoiding animal fat and cholesterol cell membranes very quickly regain their ability to allow insulin to work properly and enable glucose to properly enter cells.  Electron microscopy has demonstrated this change in a little as a week.
  • With improved insulin sensitivity the need for strict avoidance of dietary carbohydrates is reduced, blood sugar control improves, and measures like Hemoglobin A1C, the standard measure of a diabetic’s blood sugar control trend significantly downward.

Here are the highlights of what the eating approach involves:

  • First eat no animal products.  This is a black-and-white thing.  All animal products contain saturated fat and cholesterol, and undermine the success of this approach. So no meat, fish, poultry, eggs or dairy products.  This sounds extreme, but it’s far less extreme than coronary bypass surgery, amputation of the infected legs of advanced diabetic patients, or other medical procedures we use to treat complications of uncontrolled diabetes.
  • Focus on non-animal foods you enjoy. Eat all you want of fruits, vegetables, beans, and whole grains.  Try to avoid high fat vegan products like large amounts of nuts and avocado
  • Avoid adding processed vegetable oil to foods when possible.

One problem is the difficulty in finding dietitians and health care workers to guide you through this approach. Here are resources to much more informed and expert authorities on this topic:
