Eating a diet rich in heavy-fiber reduced the risk of death in people with heart disease, infectious or respiratory disease, or any cause by 22%, according to a new study.
In addition, people who were in the highest group of fiber intake (29.4 g per day for men and 25.8 grams for women) were also less likely to develop these diseases than people with the lowest fiber consumption levels (12.6 g per day for men and 10.8 grams for women).
This is a good motivation for joining the US Department of Dietary Guidelines updates of Agriculture for Americans (DGA), who called on January 31 for increased fiber intake through grains whole, fortified foods, and fruits and vegetables. DGA recommends 14 grams of fiber per 1,000 calories a day -. Totaling about 25 grams of fiber per day
Dietary fiber is the edible part of a plant that is difficult to digest - found in wheat bran and green leafy vegetables - and is known to improve health in a number of ways. It is thought to reduce the risk of heart disease, some cancers, diabetes and obesity, and is known to reduce cholesterol, blood sugar and blood pressure. According to background information in the study, published in Archives of Internal Medicine, it also binds to potential carcinogens so that the body can not flush out.
For the study, researchers examined mortality data for 219.123 168.999 men and women who completed questionnaires on their eating habits between 1995 and 1996 as part of the National Institutes of Health-AARP longitudinal Diet and health study.
During nine years of follow-20.126 men and 11,330 women died. People who ate the highest amounts of fiber were 22% less likely to die of a cause that people who ate the least fiber. In addition, men in the highest quintile were 24% less likely to suffer from cardiovascular disease, infectious or respiratory than men in the lowest quintile, and for women the risk reduction was 34%.
The researchers noted that fiber from grains, such as whole grain bread or brown rice, but no fiber from fruits, was associated with death risk reduction in men and women.
