Intestinal Flora in Aging: a Scientific Perspective on Food Intervention

The intestinal flora serves as a crucial regulator of healthy aging. With aging, the composition and function of the intestinal flora undergoes significant changes that are closely associated with various aging-related diseases. This article reviews the changes in intestinal flora associated with aging and explores the potential of natural foods to improve aging-related diseases through gut microbiota intervention. Specifically, interventions from natural food sources such as probiotics, prebiotics, appropriate dietary supplements, and nutritional intake have shown positive effects on improving gut health and delaying aging. Additionally, the article discusses the effects of different dietary patterns and nutritional restrictions on the intestinal flora and lifespan. Finally, the article summarizes the key findings of gut microbiota in nutritional intervention research on aging, providing evidence and guidance for further exploring the potential of intestinal flora intervention in anti-aging.
