The researchers explain that not only is fiber benefits the heart, which helps prevent heart attacks, but fiber from whole grains also decreases the risk of respiratory illnesses, such as pneumonia and chronic bronchitis and other infectious diseases.
In addition to fiber, the American Heart Association includes whole grains as a good source of iron, which carries oxygen in blood and selenium, known to strengthen the immune system.
Write in the Archives of Internal Medicine, scientists found that fiber whole grains – not fruits and vegetables – had the greatest impact in reducing risk of death; even of cancer. The research included data on more than 500,000 members AARP; participants from survey of eating habits study over a period of nine years.
The results showed that people who ate more fiber (30 grams per day for men) and 25 grams per day for women were 22% less likely to die from any cause during the study, compared to individuals who eat less amount of fiber (13 grams per day for men) and 11 grams per day for women.
For specific diseases, men consume a diet high in fiber had a 24% lower risk of dying from heart disease, 31% lower risk of dying from respiratory diseases, 56% lower risk to die of an infectious disease and were 17% less likely to die of cancer. Reductions in risk were similar for women.
But scientists aren't sure why fiber intake associated with lower risk of death from respiratory diseases and infectious diseases. It could be anti-inflammatory properties of the fiber, but more research is needed.
The Centers for Disease Control and prevention include whole grains in their list of foods to maintain a healthy, weight together with fruits, vegetables, dairy products low in fat and fat, fish, and lean meat and poultry cuts.
