Don't Have a Stroke: Eat Your Veggies

WebMD Health News

Oct. 5, 2000 -- They can help you control your weight; are full of vitamins, minerals, and fiber; may help protect against cancer; and besides, Mom told you to eat them.

But if you're still not in the habit of eating your vegetables, here's one more thing that may convince you: They can also lower your risk of stroke, according to a new study from researchers in Japan. It found that people who ate vegetables six or seven days per week had a 58% lower chance of stroke than those who ate vegetables only two days a week.

"These reductions in stroke risk are comparable to the benefits we see when someone gets their blood pressure under control," says Ralph Sacco, MD, associate chairman of neurology at Columbia University College of Physicians and Surgeons in New York. He was not involved in the Japanese study.

Back in 1977, researchers did a number of studies -- which including measuring vitamin C levels in the blood -- on more than 2,000 men and women in a rural Japanese community. Then they kept track of the study participants for the next 20 years with annual health exams. During that period, people in the study had almost 200 strokes.

Tokyo researchers have now looked at this data to see which factors increased the risk of stroke, and their results have been published in Stroke: Journal of the American Heart Association. They found that people with the lowest levels of vitamin C in their blood were 70% more likely to have a stroke, compared to those with the highest levels.

In addition to the finding about vegetables, "we found that people with a low concentration of vitamin C [in their blood] had a high risk of stroke," study author Tetsuji Yokoyama, MD, tells WebMD. "This low concentration may be due to lower intake of fruits and vegetables, smoking, drinking too much alcohol, and sedentary lifestyles. Thus, we advise people to engage in healthy behaviors such as eating fruit and vegetables frequently, not smoking, avoiding excess drinking, and being moderately physically active." Yokoyama is a research associate in epidemiology at the Medical Research Institute of Tokyo Medical and Dental University.
