Some scientific studies suggest that very low fat vegetarian diets may be advantageous in treating some patients with heart disease. They have not been accepted as standards for all heart disease patients because of the significant lifestyle change and the difficulty that most people find in following them. Hospital and clinic programs have been established to provide medically supervised treatment, education and support for those who wish to implement a very low fat vegetarian diet and accompanying lifestyle. (Nutritional risks and possible undesirable blood lipid effects can be of concern.) To learn more, refer to several books written about very low fat vegetarian diets listed in the References section.

A very low fat vegetarian diet emphasizes whole, unprocessed foods rich in complex carbohydrates such as whole grain breads, cereals, cooked grains, fruits and vegetables. The diet is high in heart healthy fiber, vitamins, minerals, antioxidants, and phytochmeicals. No added fats, oils or foods high in fat (avocado, olives, nuts or seeds) are allowed. All animal meat, fish, and poultry is eliminated. Protein in the diet comes from plant foods (beans, soy and tofu) as well as nonfat dairy items such as egg whites and fat free milk or yogurt.

When well planned, this diet can provide adequate calories, protein, vitamins and minerals for good nutrition. Poorly planned, there are risks for nutrient deficiencies. Specifically, low intakes of Vitamin B12, calcium, iron and protein are of concern. While there is no limit placed on the amount of food from any of the permitted food groups, calories will tend to be lower because of the very low fat and low animal food pattern. Weight should be monitored, and dietary corrections made to adjust calories if undesirable weight gain or weight loss occurs. Consultation with a registered dietitian is recommended.

It is important to consult with your physician or heathcare professional before adopting this diet. In some cases, undesirable changes in blood lipid levels can occur, specifically higher triglycerides and lower HDL cholesterol. And remember, the diet has only been shown effective when it used in combination with a total lifestyle approach.
Several different very low fat vegetarian diet programs exist, each with slightly different dietary recommendations. The dietary guidelines below are used by those who follow Dr. Dean Ornish's Heart Disease Reversal Program.
