Gut microbiome-targeted interventions are being explored as means of improving cognitive performance. A new meta-analysis of 22 randomized controlled studies has found no significant effect on improving cognition for probiotics, prebiotics and fermented foods, whether alone or used in combination.
Meal ingestion usually induces a wealth of sensations before, during and afterwards. A new brain imaging study reveals sex-specific differences in subjective responses to a palatable meal at thalamic and insular connectivity level in healthy individuals.

Foods are processed in the upper digestive tract and pass into the colon when entering the digestive system. A new paper outlines the impact of food consumption in shaping bidirectional communication between digestive responses and the digestive sensations occurring before, during and after a meal.
The last 9th Gut Microbiota for Health World Summit hold in Madrid on March updated the science behind diet, the balance between gut microbiota and the immune system, mental health, food intolerances and functional gut disorders, among others. Check out here the Summit’s official report.

A new publication from Alan T. Tang of the University of Pennsylvania focuses on explaining the relationship between gut microbiota and cerebral cavernous malformation (CCM), which is a neurological disease that leads to hemorrhagic stroke and seizure.
While initial studies focused on characterizing the gut microbiome, there has been a shift in the field towards mechanistic research focusing on microbiome influence on host phenotype. Here, science and medical writer Andreu Prados updates major breakthroughs in the field in 2019.

Alterations of the gut microbiota have previously been observed due to sleep deprivation. A novel study shows the close crosstalk between sleep quality and gut microbiome diversity, which is mediated by the pro-inflammatory cytokine IL-6.

Recent studies have widened the immune system and the gut microbiota’s role to the pathophysiology of Parkinson’s disease. Scientists suggest that intestinal infections could act as a trigger in Parkinson’s disease, through affecting mitochondrial antigen presentation and cytotoxic T cells establishment in mice.

In 1971 scientists showed for the first time the contribution of human gut microbiota in metabolizing levodopa. New findings have disentangled a gut microbial enzymatic pathway involved in metabolizing this drug, with Enteroccocus faecalis being the most efficient strain.
