Gut Microbiota and Dietary Strategies for Age‐Related Diseases

The gut microbiota influences metabolism, immune function, and gut health, which may be critical in the aging process.

• Dietary components like fiber, polyphenols, and fermented foods can enhance beneficial microbes and metabolites.
• Short-chain fatty acids (SCFAs) produced by these microbes may help reduce inflammation and protect against chronic diseases.
• Aging is associated with decreased microbial diversity and dysbiosis, leading to chronic low-grade inflammation, known as 'inflammaging.'
• Dietary strategies that include prebiotics, probiotics, and postbiotics could help restore microbial balance and address age-related decline.
• Challenges exist in applying microbiota research to clinical settings, including individual variability and limited human trials.
