Interventions

Tryptophan restriction

downin rats1

1 study

Tryptophan restriction decreases Enterobacteriaceae in rats (severe restriction, 40% and 10% tryptophan; fecal concentrations).
“Severe tryptophan restriction decreased fecal concentrations of Enterobacteriaceae, Lactobacillus, Bacteroides, and Clostridium coccoides while increasing Roseburia groups.”

Lifestyle program linked to gut microbe shifts in older adults

A 24-week trial sub-study followed 130 adults aged 60–79 at risk of dementia and found shifts towards a healthy reference microbial pattern within the intervention group.A 24-week trial sub-study followed 130 adults aged 60–79 at risk of dementia and found shifts towards a healthy reference microbial pattern within the intervention group.
