How Lifestyle And Preventive Medicine Shapes Dietary Advice
Plant based nutrition and lifestyle medicine use diet, activity, sleep and stress management as a primary tool for preventing and in some cases reversing chronic disease. Trials in this area have tested whole food plant predominant diets in type 2 diabetes, raised cholesterol and cardiovascular disease. The approach does not require everyone to become vegan, and it works best when supervised, particularly for anyone on medication for blood sugar or blood pressure, because doses often need adjusting as the diet changes.
