THURSDAY, March 28 (HealthDay News) -- Eating more fiber-rich foods appears to lower stroke risk, according to a new British study.
For every 7-gram bump in daily fiber consumption, an individual's risk for experiencing an initial stroke appears to plummet 7 percent, the investigators concluded after analyzing 20-plus years of research.
"This is important because most people in the U.S. do not eat enough fiber-rich foods," said study co-author Victoria Burley, from the Center for Epidemiology & Biostatistics at the University of Leeds in England.
"Total dietary fiber intake should be 25 to 30 grams a day from food, but on average people in the U.S. are getting only half this amount," Burley said.
Most people would have little trouble increasing overall fiber intake by 7 grams a day, the team concluded. A wide range of everyday foods -- for example, a serving of whole-wheat pasta plus a piece of fruit and a standard serving of tomatoes -- would enable people to reach this goal, the authors said.
The finding builds on prior evidence that has indicated consumption of plant-based dietary fiber -- including fruits, nuts, vegetables and whole grains -- may curb key factors that raise stroke risk, such as high blood pressure and elevated levels of so-called "bad" (LDL) cholesterol.
Strokes occur when a clot blocks a blood vessel to the brain or when a blood vessel bleeds into the brain. Stroke and other brain-based blood vessel diseases are collectively the world's second-leading killer, causing more than 6 million deaths annually and leaving large numbers of people with lasting disability.
"Everything that may be done, however small, to improve prevention is important and could have an impact on many thousands of lives," Burley said. This is particularly true for people already at risk of stroke, such as smokers, obese individuals and those with high bl
