A study from Brazil shows that jaboticaba peel, rich in phenolic compounds, can help manage blood sugar and inflammation in people with obesity and metabolic syndrome, offering significant health benefits when consumed as a powder supplement. Researchers at the State University of Campinas conducted a study involving 49 participants and found that consuming a dietary supplement with 15 g of the substance daily for five weeks enhanced glucose metabolism post-meal. The peel of the Jaboticaba berry (Plinia jaboticaba), native to Brazil’s Atlantic Rainforest, is often discarded due to its high tannin content, which gives it a puckering taste.
However, a study published in the journal Nutrition Research suggests that this skin could be highly beneficial in combating obesity and metabolic syndrome. Conducted by researchers at the State University of Campinas (UNICAMP) in São Paulo state (Brazil), the study showed that inflammation and blood sugar levels improved in volunteers with obesity and metabolic syndrome who took 15 g per day of powdered jaboticaba peel as a dietary supplement for five weeks. Jaboticaba peel contains beneficial phenolic compounds such as anthocyanins, which give the berry its dark purple color and enhance glucose metabolism.
“The phenolic compounds and dietary fiber present in jaboticaba peel have the power to modulate glucose metabolism. We observed this effect in previous studies. This study focused on the benefits of prolonged consumption and found .
