Eating fibre-rich foods also reduced incidence of coronary heart disease, stroke, type 2 diabetes and colorectal cancer by 16-24 per cent.

Per 1,000 participants, the impact translates into 13 fewer deaths and six fewer cases of coronary heart disease.

The only risk researchers uncovered from eating a large amount of whole grain, high-fibre foods was a chance of ill effects to consumers with low mineral or iron levels.

The study was commissioned by the World Health Organization to inform the development of new recommendations for optimal daily fibre intake and to determine which types of carbohydrate provide the best protection against non-communicable diseases (NCDs) and weight gain.

Most people globally consume about 20 grams (0.70 ounces) of dietary fiber per day, Mann said of the findings.

Dietary fiber includes plant-based carbohydrates such as whole-grain cereal, seeds and some legumes.

The WHO defines an unhealthy diet as one of the major risk factors for a range of chronic diseases, including cardiovascular diseases, cancer, diabetes and other conditions linked to obesity.

The team from the University of Otago in New Zealand looked at 185 clinical trials and 58 studies carried out during the last four decades involving more than a million people. These studies involved initially healthy participants, so the findings can not be applied to those with existing chronic diseases.

Consumption of 25 to 29 grams of fiber per day was sufficient, but the data suggests that an even higher intake could provide greater protection.

This is published unedited from the PTI feed. Foods that don't increase blood glucose may still be high in sugars, saturated fats and sodium. This cholesterol-lowering type of fibre is found in fruits, vegetables and grains such as oats and barley.

"The work that we have done particularly on fibre and the gut micro flora (microbiome), in Cambridge and in recent years in Dundee, means we have enough evidence from population studies, human experimental work and the biochemistry and physiological of fibre to be confident of the clear benefits to health". The latest research is the most definitive evidence of the health benefits of a high fiber intake.

Commenting on the implications Prof Gary Frost, of Imperial College London, said: "Improving the accuracy of dietary assessment is a priority area for nutrition research". There are some important considerations that arise from this Article.
