People who get dietary fibre from many sources benefit more than those who limit their intake to a single food or low-fibre diets, new research shows.
The recommended amount of dietary fibre per day is 38 grams for men and 25 grams for woman.
“Men typically get around 18 grams and women get around 15 grams,” said Julie Miller Jones, professor emeritus at Minnesota-based St Catherine University.
Daily fibre intake helps control cholesterol, blood pressure, glucose, insulin and excess weight.
It also regulates multiple facets of the digestive system. Two fruits and three vegetables servings a day can help adults get the recommended amount of fibre.
“The problem is that when consumers choose fruits or vegetables, it is often low-fibre options such as one piece of lettuce and a thin slice of tomato on a sandwich”.
Instead of looking at only plant-based sources, people should strive for a mix of fibre sources, including fibre that has been added to food in the manufacturing process.
Such foods are fibre-fortified bread, cereals, yogurt and pasta.
“A combination of naturally occurring and added fibre can increase the chances of achieving the health benefits of a high-fibre diet,” the authors noted.
The study was presented at “IFT15: Where Science Feeds Innovation” event in Chicago recently.
