Effect of dietary turmeric on breath hydrogen. Turmeric is widely used in Indian cuisine. The main constituents of turmeric are curcumin and its analogues, which are well-known antioxidant compounds. In the present study, we hypothesized that turmeric in curry might increase bowel motility and activate hydrogen-producing bacterial flora in the colon, thereby increasing the concentration of breath hydrogen. Eight healthy subjects fasted for 12 h and ingested curry and rice with or without turmeric (turmeric knockout curry). Breath-hydrogen concentrations were analyzed every 15 min for 6 h by gas chromatography with a semiconductor detector. Curry with turmeric significantly increased the area under the curve of breath hydrogen and shortened small-bowel transit time, compared with curry not containing turmeric. These results suggested that dietary turmeric activated bowel motility and carbohydrate colonic fermentation. ncbi.nlm.nih.gov/pubmed/19034660 ncbi.nlm.nih.gov/pmc/articles/PMC2871121/table/t2-ijms-11-01365/ ncbi.nlm.nih.gov/pmc/articles/PMC2871121/table/t1-ijms-11-01365/ https://jstage.jst.go.jp/article/jnsv/52/2/52_2_149/_pdf Impact of Dietary Polyphenols on Carbohydrate Metabolism. ncbi.nlm.nih.gov/pmc/articles/PMC2871121/ Inhibition of alpha-glucosidase and amylase by luteolin, a flavonoid. https://jstage.jst.go.jp/article/bbb/64/11/64_11_2458/_pdf Isolation and characterization of alpha-glucosidase inhibitor from the fungus Ganoderma lucidum. ncbi.nlm.nih.gov/pubmed/15459652
