Dietary Fibers Promote Healthy Gut Bacteria Activity: Study
Advertisement
Consuming fruits, vegetables, and whole grains provides us with healthy dietary fibres.
Researchers from the University of Copenhagen have now found that these fibres are essential in maintaining a balance between the production of beneficial and harmful substances in the colon by influencing bacterial behavior.
The research, published in the scientific journal Nature Microbiology, revealed that different types of bacteria in our colon compete to utilize the essential amino acid tryptophan, leading to either beneficial or harmful outcomes for our health. The study found that consuming a high amount of dietary fiber helps gut bacteria convert tryptophan into beneficial substances.
Researchers have discovered that dietary fibres, found in fruits, vegetables, and whole grains, not only convert into healthy short-chain fatty acids but also prevent tryptophan from becoming harmful substances, instead promoting its conversion into beneficial compounds. This highlights how dietary fibres influence gut bacteria composition and behavior, contributing to overall health. Protein-rich foods like chicken, turkey, salmon, eggs, and legumes are key sources of tryptophan, which must be obtained through diet.
