NEW YORK, 12 Jan. – New research commissioned by the World Health Organization has found that the inclusion of many fiber and whole grains in the diet can help reduce the risk of chronic diseases such as coronary heart disease, stroke, type 2 diabetes and colorectal cancer.

Executed by researchers from the University of Otago, New Zealand and the University of Dundee, Scotland, the new meta-analysis examined 1

85 observational studies containing data for 135 million person-years – takes into account the number of people in the study and the amount of time each person spends in the study – and 58 clinical trials involving 4,635 healthy adult participants.

Researchers focused on the effects of dietary fiber and whole grains on the risk of premature deaths and rates of coronary heart disease, cardiovascular disease and stroke, as well as rates of type 2 diabetes, colorectal cancer and tumors associated with Obesity: astb, endometrial, esophageal and prostate cancer.

The results, published in The Lancet suggested that those who ate the highest amount of fiber, with a daily intake of between 25g and 29g, benefited from a 15-30% reduction in mortality related to all causes and cardiovascular compared to people who ate the least amount of fiber.

In addition, eating high-fiber foods has also reduced rates of coronary heart disease, stroke, type 2 diabetes and colorectal cancer from 16 to 24 percent.

In addition, there seemed to be a dose-response relationship, suggesting that a higher intake of dietary fiber from 25 to 29 g per day could bring even greater benefits for cardiovascular disease protection, type 2 diabetes and colorectal cancer and of the breast.

The increase in fiber ingestion was also associated with lower body weight and cholesterol, compared to lower assumptions.

High levels of whole grain intake were also associated with a 13 to 33 percent reduction in the risk of developing chronic diseases and for every 15g increase in whole grains consumed per day, total deaths and coronary heart disease rates, Type 2 diabetes and colorectal cancer decreased from 2 to 19 percent.

Whole grains were also associated with a reduction in body weight, with researchers explaining that whole grains are rich in dietary fiber, which could explain their beneficial effects.

However, the study found only limited support for a low glycemic index and a low glycemic load offering protection against type 2 diabetes and stroke. They explained that foods with a low glycemic index or a low glycemic load may also contain added sugars, saturated fats and sodium that could explain the health benefits of this type of diet being less clear.

Most people consume less than 20g of dietary fiber a day. Rich sources of dietary fiber include whole grains, legumes, vegetables and fruit. – AFP-Relaxnews
