Best Foods to Improve Gut Health: A Comprehensive Review
Introduction and Overview
The gut microbiome plays a crucial role in maintaining overall health and well-being. An imbalance of the gut microbiota, also known as dysbiosis, has been linked to various diseases, including inflammatory bowel disease, obesity, and mental health disorders. Dietary interventions have been shown to be effective in modulating the gut microbiome and improving gut health. This review aims to summarize the current evidence on the best foods to improve gut health.
Methodology and Testing Process
A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science databases. Studies published between 2010 and 2023 were included, with a focus on human clinical trials and observational studies. The search terms used were "gut health," "gut microbiome," "dietary interventions," and "food components." A total of 150 studies were identified, and 50 studies met the inclusion criteria.
