The ‘Myrciaria dubia’, an exotic fruit from the Amazon commonly known as camu-camu, has been shown to be effective in preventing obesity in mice and could play a key role in the fight against this disease and other metabolic diseases, says a study published in the medical journal GUT.
At the end of the experiment, the specimens that had been fed with the fruit had gained 50% less weight than the mice that had not ingested the extract, and their weight gain profile was similar to that of the control group.
Camu-camu exceptional composition
Apparently these effects may be related to the exceptional chemical composition of this food, it contains 20 to 30 times more vitamin C than kiwi and five times more polyphenols than blackberries.
“In previous work, we have shown the beneficial effects for health of certain small fruits rich in polyphenols,” says André Marett, co-author of the study.
According to the authors, the camu-camu extract could have caused an increase in resting metabolism of animals, which in turn led to a lower weight gain. This improved glucose tolerance and insulin sensitivity, and also reduced the concentration of endotoxins in the blood and the inflammatory response.
Intestinal microbiome reconfiguration
Marret emphasizes that all the changes were accompanied by a “reconfiguration of the intestinal microbiota”: a proliferation of ‘A. muciniphila ‘and a strong reduction of the bacteria of the genus’ Lactobacillus’. In his opinion, this consequence is responsible for the “positive effects on the metabolism”.
Now the goal is to see if camu- camu produces the same metabolic effects in humans. The toxicity of this fruit should not be a problem, because its extract is already marketed to combat fatigue, stress and to stimulate the immune system.
