Gut: 12 fiber-rich foods to fight germs


The antibiotic resistance in humans is largely based on the gut microbiome (also called intestinal flora). The microbes that constitute it are known to survive contact with antibiotics.

Antibiotic resistance is today one of the most serious threat affecting global health and food security. The antibiotics are medicines used to treat and prevent infections bacterial. “A growing number of infections, such as pneumonia, tuberculosis or gonorrhea, salmonellosis, are becoming more difficult to treat, warns the World Health Organization (WHO). The antibiotics used to treat them lose their efficiency“.

According to one new study published by scientists from the Agricultural Research Service and their colleagues at mBio, people who adopt a diversified diet with at least 8 to 10 grams of soluble fiber per day would present less resistant microbes antibiotics in their intestines.

Diet can be a weapon against antibiotic resistance

“The results lead directly to the idea that dietary modification has the potential to be a new weapon in the fight against antimicrobial resistance. And we’re not talking about eating an exotic diet either, but a diverse, fiber-adequate diet that some people are already following,” explained molecular research biologist Danielle Lemay of the Center for Western Human Nutrition Research. ARS in Davis, California and lead on the study.

The study was conducted on 290 healthy adults.

The researchers found that those who regularly consumed higher levels of fiber had lower levels of antimicrobial resistance genes among their gut microbes.

Scientists have also linked it to proteins. From lower protein levelsespecially from beef and pork, are significantly correlated with lower levels of antibiotic-resistant microbes.

Antibiotic-resistant microbes: rely on soluble fiber

According to the researchers, the factor that would have the greatest impact on antibiotic-resistant microbes would be the level of fiber. And particularly the soluble fiber “for maximum benefit,” suggested Danielle Lemay.

The latter form a gel in the intestine by absorbing excess water, which thickens the contents of the stomach and delays its passage through the intestine. Soluble fibers are known to promote the balance of the intestinal flora.
