Drinking beet juice increases blood flow to the brain in older people, a finding that suggests the dark red vegetable may fight the progression of dementia, a new study shows.
Beet roots contain high concentrations of nitrates, which are converted into nitrites by bacteria in the mouth. And nitrites help open blood vessels in the body, increasing blood flow and oxygen to places lacking in oxygen.
Previous studies have shown that nitrites -- also found in high concentrations in celery, cabbage, and other leafy, green vegetables like spinach -- widen blood vessels, but researchers say this was the first to find that nitrites also increase blood flow to the brain.
