Consume more whole grains decreases risk of premature death, says a new study. And it's fiber that makes the difference.
Researchers explain that not only benefits the fiber, to help prevent heart attacks, but fiber from whole grains also lowers the risk of respiratory diseases such as pneumonia, and chronic bronchitis, and other infectious diseases.
In addition to the American Heart Association shows fiber whole grains as a good source of iron, which transports oxygen in the blood and selenium, known in order to strengthen the immune system.
Write in the archives of internal medicine, scientists found that fiber from whole grains-not fruits and vegetables-had the largest impact on reducing the risk of death. also from cancer. Research includes data on more than 500 000 AARP members. surveying study participants about their eating habits during nine years.
The results showed that people who ate the most fibre (30 grams per day for men and 25 grams per day for women) was 22 percent less likely to die from any cause during the study, compared to individuals who ate the least amount of fiber (13 grams per day for men and 11 grams per day for women).
For specific diseases, men are consuming a high-fiber diet had 24 percent lower risk of dying from heart disease, 31% reduced risk of dying from respiratory diseases, 56 percent lower risk of dying of a communicable disease, and was 17 percent lower risk of dying from cancer. Reductions in risk was similar for women.
But scientists are unsure why high-fiber intake was associated with lower death risk from respiratory and infectious diseases. It may be fiber's anti-inflammatory properties, but more research is needed.
U.S. Centers for Disease Control and Prevention include whole grains added to the list of products in order to maintain a healthy weight. together with fruits, vegetables, low-fat and fat-free milk, fish, and lean cuts of poultry and meat.
