A fiber-rich diet could reduce the risk of dying from heart disease, respiratory disease and other causes by 22 percent, according to researchers at the National Cancer Institute of USA. UU. Fiber has also been linked to a lower risk of developing heart disease, some cancers, diabetes and obesity, the researchers added. In addition, fiber helps the intestinal evacuation and reduces the levels of cholesterol, blood sugar and blood pressure. It also promotes weight loss and reduces inflammation, they scored. The dietary guidelines for Americans 2010 of the USDA recommended consuming fruits, vegetables and fiber-rich whole grains, said leading researcher Yikyung Park, scientific plant of the Institute. Guidelines recommend fourteen grams per thousand calories of dietary fiber per day, or 25 grams of fiber a day. Our study agrees with these recommendations, and suggests that dietary fiber intake is associated with lower mortality, pointed out.
The report appears in the online edition of February 14 in the journal Archives of Internal Medicine. For the study, the Park team collected data on 388,122 men and women who participated in the study of diet and health at the national institutes of health and AARP. As part of the study, participants completed a questionnaire about diet. The amount of fiber that people in the study ate varied from 13 to 29 grams per day in men and eleven to 26 grams per day for women. During nine years of follow-up, 11,330 and 20,126 men died. The researchers found that men and women who consumed more fiber were 22 percent less likely to die during the nine years than those who ate less.
In addition, the risk of cardiovascular and respiratory disease was reduced from 24 to 56 percent among men who consumed the highest amount of fiber, and between 34 and 59 percent among women, found the Group of Park. Fiber from grains, but not of the fruit, is related to lower risk of death, researchers scored. Previous studies have focused on the relationship between fiber intake and cardiovascular disease, but few have examined the relationship between dietary fiber and the risk of death from any cause, said Park. Our analysis complements the existing literature and suggests that dietary fiber intake is associated with a lower probability of death. Dr. Frank B. Hu, Professor of nutrition and epidemiology in the Faculty of health at Harvard, and co-author of a companion editorial in the journal, said that this study provides further evidence to support the current dietary guidelines recommending a higher intake of fiber. Commenting on the study, Samantha Heller, dietician, nutritionist, fisiologa report and coordinator of clinical nutrition of the Centre for the care of the Cancer of the Hospital Griffin in Derby, Connecticut, said that whole grains are the better.
