As revealed by a new study from McMaster University, microbes in the small intestine interacting with gluten in a person diagnosed with celiac disease can trigger an immune reaction.

Individuals may experience recurrent weight gain and re-emergence of metabolic complications, a phenomenon sometimes called the "yo-yo effect". But growing evidence of the role of gut microbiota in obesity and metabolic health may bring the potential to address this problem in new ways.

A recent study, led by Dr. Mahmoud Salami from the Physiology Research Centre at Kashan University of Medical Sciences in Kashan (Iran), has found that a daily dose of probiotic Lactobacillus and Bifidobacterium bacteria taken over 12 weeks may improve cognitive function in elderly Alzheimer’s patients.

Previous studies have identified Akkermansia muciniphila as an important bacterium in metabolic health—able to prevent the development of obesity in animal models. Until now, however, its mechanisms were unclear and its effects had never been tested in humans.

Now a recent study, led by Dr. Nicola Santoro from the Department of Paediatrics at Yale University in New Haven, Connecticut (USA), has found that the gut microbiota of obese youth may drive a higher accumulation of energy than that of lean adolescents through an elevated production of short-chain fatty acids (SCFAs) and a higher capability to oxidize carbohydrates.

In a recent paper by Perry et al., researchers describe an investigation into the putative mechanisms by which gut microbiota alterations may lead to obesity, insulin resistance, and metabolic syndrome. Authors describe increased production of acetate by altered gut microbiota in rats. They link this to activation of the parasympathetic nervous system, increased glucose-stimulated insulin secretion, higher ghrelin secretion, hyperphagia, and obesity. Thus, they point to increased acetate production as a driver of metabolic syndrome.
