The China-Finland study reveals the health benefits of oats and rye bran

, July 4 (Xinhua) -- A research project between China and Finland has revealed the mechanism by which oats and rye bran fiber promote beneficial microbial growth in the gut.
Finnish researchers said Wednesday that in a joint project by the University of Eastern Finland, the Finnish National Technical Research Center and the School of Biological Sciences of the University of
, mice were fed a high-fat diet rich in oats or rye bran, and the results showed that oats strengthened the lactobacillus lactobacillus genus in the intestines of mice, while rye bran increased levels of Bifidobacteria in the intestines.
large number of microorganisms in the intestines of animals are called gut microbiomes. Dietary fiber has previously been known to cause changes in the function of the intestinal bacteria, thus regulating the intestinal environment, but the specific regulation and metabolic pathways and mechanisms are largely not clear. According to the study, the study identified differences in metabolites produced by the gut microbiota after supplementing oats and rye bran fiber, and how they interact differently with hosts in metabolism.
study found that oats affect the function of bile acid receptors, and rye bran alters the production of bile acid to improve the metabolism of cholesterol in different ways. Both reduce liver inflammation associated with diseases such as fatty liver disease and inhibit weight gain.
study may promote the development of products that provide separate oat or rye bran fiber components, and the benefits of ingesting both fibers include increased intake of other beneficial substances in the body, Marjuka Kolemenen, a professor at the University of Eastern Finland, told Xinhua in an interview.
in Finland, oats and rye are popular foods. Rye bread is a traditional Finnish specialty.
