A recent study shows that millions of people are at risk of premature death because they do not eat enough fiber. According to the British Daily Mail, a study by the World Health Organization found that people who get too much fiber in their diet have a lower risk of premature death by It also reduces the risk of a heart attack, stroke, or type 2 diabetes or bowel cancer by up to a quarter. However, the vast majority of adults in Britain, about 91 per cent, eat less than the recommended daily intake, There are similar statistics United States.
These results are in contrast to low-carbohydrate diets that have been popular in recent years, leading to lower fiber consumption. Fiber, sometimes referred to as roughage, is vital for digestion and helps to feel fuller for longer periods. Vegetables and grains, as well as bread and pasta made from whole grain and whole grains, but the high popularity of diets, which often rely on little fiber intake, means that many people get very little of these ingredients Of.
Professor John Cummings, a researcher at the University of Dundee, Scotland, said the new research published in the Lancet medical journal would have a significant impact, noting that it was a crucial moment in fiber intake. "The work we have done means we have enough Evidence from studies, human experimental work, biochemistry and physiology of the importance represented by fiber to be confident of the obvious benefits it has for our health. "
His team collected results from more than 230 previous studies, involving 215,000 people.

The researchers found that people who ate more than 30 grams a day of fiber, the amount recommended by the Public Health Authority of England, were less likely to die early, 24 percent compared to people who ate 8 grams a day, and those who ate For more than 35 grams, the risk has fallen by more than a third. To make sure people have enough fiber, potatoes, pasta, bread and other starchy carbohydrates, known traditional foods, should be the staple ingredients of a healthy diet, health officials say.
To eat 30 grams of fiber, people should eat five servings of fruits and vegetables per day, plus 2 full grains biscuits of breakfast cereals, and two thick slices of whole bread and potatoes without peeling. But decisively, people should choose options Whole grain foods in order to get the nutrition from the carbohydrates they eat.
"Our results provide compelling evidence to focus on increasing dietary fiber and replacing whole grains with whole grain," said Professor Jim Mann of the University of Otago, New Zealand, who also worked on the new research. "Whole foods rich in fiber require a lot of flavor and retain much of their composition. The intestines increase satiety and help control weight, and can positively affect the levels of fat and cholesterol.
His team found that each increase of 8 grams of dietary fiber eaten daily reduces early death by 5 to 27 percent, and said consuming 25 grams to 29 grams every day was enough but more than 30 grams gave greater protection against stroke, cancer Breast also.
"The challenge we face is that many people in the UK do not eat that fiber," said Professor Kevin Whelan of Kings College London. "The main sources of fiber in the UK diet are cereals, bread Pasta, rice, breakfast cereals, vegetables and fruit. "
"People should think of ways to increase fiber intake by changing food preparation methods, for example, not to peel potatoes, to go to whole grains to replace sugary snacks, as well as fruits, vegetables, nuts and seeds," he said.
"The sheer volume of evidence, coupled with the consistency of the results of observational studies and experiments, shows that we can now be quite confident of the consumption of fiber from all sources, especially whole grains," said Dr. Ian Johnson of the Institute of Biological Sciences at Quadram, Norwich. Provide great protection against common diseases later in life that now puts great pressure on national health institutions. "
"However, as with most studies, most of the evidence comes from observation, "One has to be cautious about the conclusions, but I tend to believe that the overall results are directly and consistently consistent with other research findings, and recommendations to increase the amount of dietary fiber and replace whole grains with whole grains are expected to benefit human health."
