Food insecurity linked to gut microbiome changes in children

Article excerpt

Children experiencing food insecurity show distinct changes in their gut microbiome, researchers reported at ASM Microbe 2026. The finding adds biological evidence to what public health officials have long suspected: poverty's impact on nutrition leaves a molecular mark on developing immune and digestive systems. Scientists identified specific microbial shifts in food-insecure kids that differ from well-nourished peers. The discovery could help explain why food insecurity correlates with higher rates of infection and chronic illness in childhood. Researchers say the work underscores nutrition as a public health priority, not merely a poverty metric.
