Total dietary intake of polyphenols is much higher than that of all other classes of phytochemicals and known dietary antioxidants. However, despite their wide distribution in plants, the health effects of dietary polyphenols have come to the attention of nutritionists only rather recently. We tested the potential of dietary polyphenols in our gut health and integrity models.
We have shown that consumption of dietary polyphenols prevented Salmonella-infection related symptoms. They decreased infection-induced intestinal permeability, diarrhoea and inflammation of the gut. “These results indicate that polyphenols could be of benefit in increasing resistance to intestinal pathogens,” says project manager Dr. Ingeborg Bovee.
