The Importance of Assessing the Gut Microbiota in the Small Intestine

New research shows that a long-term low FODMAP diet can be used effectively for IBS. This is huge as there have been many theoretical concerns about using a low FODMAP diet long-term, such as negative impacts to the gut microbiota, nutrition levels, and quality of life. 

However, we’ll cover each common criticism and answer them with science. 

And if you have any additional questions about low FODMAP that you would like answered in the future, let me know in the comments!
