Nutrition Evidence Alert – February 2022 – Research Summary

Welcome to the February edition of the Nutrition Evidence Alert.

We’ve put together a shortlist for you of the latest scientific nutrition evidence available, enhanced by the BANT indexing team. Topics covered in the science this month include the role of probiotics in relation to both acute Covid-19 infection as well as long-Covid, a look at the relationships between oral health and Covid-19 and, continuing this theme, a focus on the impact of malnutrition and Covid-19 outcomes. Also in the line up is a systematic review on acceptance and commitment therapy for anxiety and an examination of the effects of a gluten-free diet on gut microbiota. All these, and others, are listed below.

We are hiring!

We are looking to expand our Expert Reviewer Panel. If you have a PhD or masters level qualification in nutrition or related health field, are experienced in critical appraisal of medical science and would like to know more about what is involved as a Nutrition Evidence Expert Reviewer, please send a message to database manager, Clare Grundel on [email protected].
