(6 mins) Transcript. Dr Greger's summary: "Even if we could accurately diagnose SIBO, if there is no difference in symptoms between those testing positive and those testing negative, then what's the point?"

(5 mins) Transcript. Dr Greger's summary: "It may not be the number of bacteria growing in your small intestine, but the type of bacteria, which can be corrected with diet."

Excerpts from the video:

"So, while we don’t have sound data that something like a low-FODMAP diet has any benefit for SIBO-symptom patients, there have been more than a dozen randomized controlled trials putting fiber to the test and, overall, there was a significant improvement in symptoms among those randomized to increase their fiber intake."

"“All the evidence points to a physiological need for about 50 g [of] fiber per day, which is the amount contained in the traditional African diet and associated with the prevention of westernized diseases.” That’s approximately twice what’s typically recommended, and three times more than what most people are getting day to day."
