Hypothesis
The molecular adaptations of a low-protein diet on gut health and their systemic effects on protecting against age-related diseases remain unclear.
Conclusion
Low protein diets improve metabolic and immune health in aging female mice by altering gut microbiota.
Supporting Evidence
- Low protein diets reduce the abundance of Bacteroides and increase Verrucomicrobiota.
- Mice on low protein diets show improved glucose clearance.
- Gene set enrichment analyses indicate regulation of immune and inflammatory pathways.
Takeaway
Feeding mice a low protein diet helps them stay healthier as they get older by changing the bacteria in their gut.
Methodology
Female mice were fed either a normal protein or low protein diet for 20 weeks, and their feces were analyzed for microbiota composition and metabolic health.
Participant Demographics
Female mice, 15 months of age.
