Extracts from pineapple guava exhibit antioxidant activity, may prevent digestive problems caused by disaccharidase deficiency

A study published in the journal Phytotherapy Research has found that extracts from pineapple guava (Feijoa sellowiana) may prevent digestive problems caused by a deficiency in disaccharidases and oxidative stress-related diseases. The study has also found that pineapple guava possesses antioxidant properties.

• Previous studies have shown that pineapple guava contains various biological activities, including antibacterial and anti-cancer properties in various cellular models. However, its activity on human intestinal epithelial cells has not yet been studied.
• Researchers at Federico II University of Naples and La Sapienza University of Rome in Italy examined the effects of pineapple guava extract on the viability, membrane peroxidation, disaccharidase activities and proliferation of in vitro models of human intestinal epithelial cells.
• For the study, they exposed intestinal epithelial cells Caco-2 and HT-29 to pineapple guava extract for 24 hours.
• Results showed that pineapple guava extract only increased lactase and sucrase?isomaltase activity in Caco?2 cells.
• In both cell models, pineapple guava extract reduced cell proliferation and prevented lipid peroxidation compared to control conditions.
• The researchers suggest that pineapple guava is particularly beneficial to disaccharidases deficit and as an adjuvant treatment to oxidative stress-related diseases.

In conclusion, these findings suggest that the consumption of pineapple guava extracts is a safe and effective measure to prevent digestive problems and to treat diseases related to oxidative stress.
