The role of gut microbiota in shaping immune responses has led scientists to explore the modulation of the immune system as a mechanism underlying the health benefits of probiotics. A new systematic review and meta-analysis of 9 randomized clinical trials suggest probiotics may reduce the incidence of respiratory and gastrointestinal tract infections in generally healthy children and adults.

Although the COVID-19 pandemic has shifted the focus of research for scientists worldwide, major breakthroughs in gut microbiome science have been made in 2020. In this last post of the year, we bring you articles from our blog that cover the major advances in the gut microbiome in 2020, from bench to bedside.

Fermented foods are a known source of lactic acid bacteria. A high-throughput sequencing analysis of food and human metagenomes proves that fermented foods are a source of lactic acid bacteria for the gut microbiome, and that abundance is shaped by both age and lifestyle.
