Infections: Does eating cranberries increases the effectiveness of antibiotics?

Rich in vitamins, fiber, water and antioxidants, cranberries are considered a superfood.

Small red berries may even help antibiotics act, according to a recent study.

Preventing colds, relieving urinary tract infections, protecting the stomach, protecting the heart… The therapeutic effects of cranberries have not finished surprising us.

In fact, the blueberry’s cousin is the subject of much scientific research on its properties. According to the latest study, it could improve the effectiveness of antibiotics. According to mouse research published in the journal Advanced Science by Canadian researchers, bacteria in infections (urinary, pulmonary and gastrointestinal infections) are more susceptible to treatment antibiotics through the presence of cranberry extracts.

In other words, consuming cranberries during antibiotic treatment increases its effectiveness. An effective way to combat antibiotic resistance, which the World Health Organization (WHO says) is “a global public health problem.” The action of cranberries on antibiotics will first have to be checked on humans.

Cranberries as antibiotics?

If cranberries act on infectious bacteria, it is thanks to the presence of molecules called proanthocyanidins. “There are several types of proanthocyanidins and they can work together to achieve this result. We will need to do more research to determine which ones are most active in synergy with the antibiotic,” says Éric Déziel, professor of microbiology at INRS and co-author of the study.
