06 Aug 2019 --- Both lactic acid bacteria and gut bacteria contribute to the health benefits of rye, according to a new study from the University of Eastern Finland. Gut microbes seem to play an important role in turning rye’s compounds into a format that can be easily absorbed by the body, making it possible for them to have a greater effect, the researchers note. Published in Microbiome, the study used a metabolomics approach to analyze metabolites found in food and the human body. The study findings could provide an explanation for some of the health benefits of rye, such as improved blood sugar levels and a lower risk of cardiovascular disease (CVD).
