Is a raw vegan diet healthy for diabetes and high blood pressure?

Yes: Vegetables are low in sugar, and fill you up because of fiber. If you follow that diet, you should be able to reduce your blood sugar and get better control of diabetes. Foods high in potassium and low in sodium such as bananas will help to lower your blood pressure.

Limited: You will probably eat less because the food doesn't taste as good, and being less salty will help your hypertension. Vegans have the high moral ground but the claims of major health benefits are refuted by the recent big studies -- control for their other habits and they don't live longer or have any less of any major category of illness.

Yes but: With any vegetarian diet, it is hard to get all the nutrients your body needs. A raw diet will make it harder, still. However, switching to a healthier vegetarian diet should help control diabetes and high blood pressure if it is associated with exercise and weight loss. If you are serious, make an appointment with a registered dietitian to make sure you get all the nutrients you need.
