Does eating bananas prevent certain cancers?

This is information that seems unlikely. However, researchers have shown that resistant starches, contained among others in bananas, prevent certain cancers.

[EN VIDÉO] Interview: Cannabis, an anti-carcinogenic substance?
In France, the question of cannabis remains sensitive since, according to estimates, more than 4 million people aged 12 to 75 have already used it. This narcotic is the subject of numerous studies with contradictory conclusions. Futura went to meet Paul Hofman, director of the Nice pathology laboratory and pioneer researcher in the detection of lung cancer, to find out more about this substance.

The bananas have the power to prevent cancer? The results of a recent clinical trial, published in Cancer Research Prevention, might suggest. In fact, scientists have studied whether a daily intake of 30 grams of resistant starch — a type of starch that is not digested by the function of the small intestine

Bananas, the anti-cancer gesture for people with Lynch syndrome

The results of this clinical trial are only of interest in a very limited context. By no means do these results suggest that resistant starches prevent all cancers in the general population. On the other hand, they provide interesting data on a possible means of preventing non-colorectal cancers in people with Lynch syndrome.

The 918 participants in this trial were separated into two groups: a group that consumed 30 g per day of resistant starch in powder form and a group that consumed a placebo.
The medicine…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/4/2/b/42bf5c01f8_50038191_placebo-quatre-medicaments-nih-wiki-dp.jpg” data -url=”https://news.google.com/health/definitions/medicine-placebo-11701/” data-more=”Read more”>placebo. The follow-up was done over the long term. If the patients in the “resistant starch” group took this supplement for four years, their state of health and the appearance of cancers were examined for almost ten years for the majority and up to twenty years for some of them. .

The results show that resistant starches have no effect on In epidemiology, incidence refers to the number of new cases of a disease that have appeared during a given period of time.

The effect is particularly noticeable on cancers of the upper gastrointestinal tract. In the “resistant starch” group, 27 people developed non-colorectal cancer compared to 48 in the placebo group; more than two years after the start of the clinical trial.

The scientists conclude that resistant starches have a protective effect against non-colorectal cancers in people with Lynch syndrome, although they still note certain limits to their result. Indeed, their first hypothesis was that resistant starches actually have an effect on the prevention of colorectal cancers, which they could not show here.
