Vegetarian diets in cardiovascular prevention.
There is growing evidence that consumption of a vegetarian diet as well as specific components of a vegetarian diet lower the incidence of cardiovascular disease (CVD) and death. Vegetarian diets lower the probability of developing CVD, are effective in altering serum lipids, are beneficial in reducing blood pressure, improve glycemic control and insulin sensitivity, reduce weight, and lower mortality. Vascular effects of a vegetarian diet include a thinner carotid IMT and lower brachial artery resistance. Health care providers should be aware of the types of vegetarian diets and their risks and benefits in order to guide patients' dietary habits with the ultimate goal of reducing their CVD risk. While a patient does not have to become a complete vegetarian to reduce their CVD risk, they can make simple changes in their diet that are effective in risk reduction.
