Microbiome: Effects of Ageing and Diet

Area of Science:

• Microbiology
• Gastroenterology
• Nutritional Science

Background:

• The intestinal microbiota and its collective genomes (microbiome) are crucial for host health.
• Next-generation sequencing (NGS) reveals significant age and diet influences on the microbiota.
• The exact mechanisms by which diet alters intestinal microbiome function remain unclear.

Purpose of the Study:

• To review age-related changes in the intestinal microbiota from adulthood to old age.
• To analyze the association between these microbial shifts, dietary patterns, and lifestyle factors.
• To explore potential nutritional strategies for improving health in the elderly by targeting the aging microbiota.

Main Methods:

• Literature review of studies on intestinal microbiota composition and function.
• Analysis of the impact of aging on the gut microbiome.
• Examination of the relationship between diet, lifestyle, and the intestinal microbiome in different age groups.

Main Results:

• Intestinal microbiota composition and function undergo significant alterations during aging.
• Dietary patterns and lifestyle factors are strongly associated with these age-related microbial changes.
• Physiological changes in the digestive tract and immune system accompany microbiota modifications in the elderly.

Conclusions:

• Age-related changes in the gut microbiome are linked to diet and lifestyle.
• Targeted nutritional interventions may help mitigate negative microbiota shifts in aging individuals.
• Further research is needed to establish precise dietary strategies for optimizing the health of the elderly through microbiome modulation.
