what it claims

Do not reject fiber if you experience bloating; instead, adjust your diet gradually to adapt your gut microbiota, as fiber fermentation is a normal process and not a sign of inflammation.

Dr. Bulsiewicz highlights a key distinction between fermentation and inflammation, a point supported by gastroenterology research: gas production is a natural byproduct of bacterial fiber metabolism (meta-analysis, Nature Reviews Gastroenterology & Hepatology). It is scientifically established that the microbiota can adapt to an increased fiber intake through the modulation of bacterial diversity, often referred to as 'gut training' (RCT, Cell Host & Microbe). The claim that bloating is not inherently pathological is robust, although individual experience can vary greatly in cases of functional disorders such as irritable bowel syndrome (IBS). The advice to adjust gradually is a cautious and recommended approach to avoid digestive discomfort while maintaining the metabolic benefits of fiber. There is no exaggeration here, as the creator does not offer a universal solution, but rather a strategy for personalized tolerance.
