Abstract/OtherAbstract:
PURPOSE OF REVIEW: To summarize the relevant publications during the last 12 months supporting that diet can influence gas-related symptoms in the absence of a malabsorption state. RECENT FINDINGS: Gas symptoms during carbohydrate fermentation: a diet incorporating beans is well tolerated by a majority of individuals involved in a program of heart disease biomarkers. By contrast, in patients with irritable bowel syndrome, a diet avoiding fermentable carbohydrates improved gas-related abdominal symptoms. The rate of fermentation determines the production of abdominal symptoms, and many slowly fermentable fibers have a rapid fermentation profile that can generate abdominal symptoms.Modulation of visceral sensitivity: diet can influence gas symptoms by increasing the tolerability of the intestine to gas. Capsaicin decreases visceral hyperalgesia and improved bloating in patients with irritable bowel syndrome.Changes in gas-producing bacteria: different strains of Lactobacillus have antimicrobial properties against gas-forming coliforms. New clinical studies show beneficial effects of prebiotics and probiotics on abdominal bloating. SUMMARY: Actual data suggest that diet could improve gas-related abdominal symptoms acting on several mechanisms: gas production, visceral hypersensitivity and modulation of gas-producing enteric bacteria.
