Consumption of polyphenol-rich foods (e.g., fruits, vegetables, tea, cocoa) alters gut microbiota composition by promoting beneficial bacteria (Lactobacillus, Bifidobacterium) and inhibiting harmful pathogens, thereby reducing inflammation and improving metabolic health.
Increase your intake of polyphenol-rich foods such as berries, dark chocolate, green tea, and olive oil. These compounds feed beneficial gut bacteria like Lactobacillus and Bifidobacterium while inhibiting harmful ones. This process reduces inflammation and supports metabolic health, even if the polyphenols themselves are processed by gut bacteria rather than directly absorbed.
Dietary polyphenols may alter the gut microbiota of the host... These polyphenols encourage the growth of healthy microorganisms that are favorable for human health, the well-known probiotics Lactobacillus and Bifidobacterium.
