LIMIT OF FIBER CONSUMPTION FOR GOOD HEALTH

Researchers and public health organizations have been talking about the benefits of  consuming  fiber, but the question is how much fiber should we consume, exactly?

This question has prompted the World Health Organization (WHO) to commission a new study. The results appear in the journal of a famous news journal.  

The new research aimed to help develop new guidelines for dietary fiber consumption, as well as reveal which carbs protect the most against noncommunicable diseases and can stave off weight gain.

Noncommunicable diseases are also called chronic diseases. They typically last for a long time and progress slowly. According to WHO, there are "four main types of noncommunicable diseases:" cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes.

Professor Jim Mann, of the University of Otago, in New Zealand, is the corresponding author of the study, and Andrew Reynolds, a postdoctoral research fellow at Otago's Dunedin School of Medicine, is the first author of the paper.

Prof. Mann explains the motivation for the study, saying, "Previous reviews and meta-analyses have usually examined a single indicator of carbohydrate quality and a limited number of diseases, so it has not been possible to establish which foods to recommend for protecting against a range of conditions."

To find out, the researchers performed a meta-analysis of observational studies and clinical trials.

Dailt intake of 225-29 grams of fiber is ideal.

Doctors  examined the data included in 185 observational studies — amounting to 135 million person-years — and 58 clinical trials which recruited over 4,600 people in total. The studies analyzed took place over almost 40 years.

The scientists investigated the incidence of certain chronic diseases, as well as the rate of premature deaths resulting from them.

These conditions were: coronary heart disease, cardiovascular disease, stroketype 2 diabetescolon cancer, and a range of obesity-related cancers, such as breast cancerendometrial canceresophageal cancer, and prostate cancer.
