Macro partitioning
Plant-based, high-fiber diets promote the growth of beneficial bacteria (e.g., Prevotella, Faecalibacterium prausnitzii) that produce short-chain fatty acids (SCFAs) like butyrate, which reduces inflammation and protects against age-related diseases.
Eat more plants, especially high-fiber ones like vegetables, fruits, legumes, and whole grains. This feeds good gut bacteria that produce anti-inflammatory compounds (SCFAs) to protect your gut and overall health as you age.
ModerateSupportsMEDIUM confidence
plant-based diets have a higher fiber content than animal-based diets and microbial fermentation of dietary polysaccharides can provide up to 10% of the energy intake by human... high-fiber content diet stimulates variations in the gut microbiota towards performing several beneficial functions such as protection from inflammation, obesity, diabetes, heart disease, and high blood pressure

More from this paper
- Aging is associated with a significant decrease in the abundance of beneficial gut bacteria, particularly Bifidobacteria, and a reduction in the production of short-chain fatty acids (SCFAs) like butyrate, which contributes to gut inflammation and immune system decline.Moderate
- Supplementation with prebiotics (e.g., inulin, FOS) and probiotics (e.g., Bifidobacteria) can increase the abundance of beneficial bacteria, reduce inflammation markers, and improve stool frequency in the elderly.Moderate
