By Shereen Jegtvig NEW YORK (Reuters Health) – People who eat a vegetarian diet tend to have lower blood pressure than non-vegetarians, according to a new review of past studies. Researchers said for some people, eating a vegetarian diet could be a good way to treat high blood pressure without medication. Vegetarian diets exclude meat, but may include dairy products, eggs and fish in some cases. High blood pressure contributes to a person’s risk of heart disease, stroke, kidney disorders and other health problems.
