AB High-fat diets have been associated with lower gut and fecal abundances of genusBifidobacterium. Here, we investigated whether commonly consumed dietary free fatty acids haveany detrimental effect on the growth of B. adolescentis, B. bifidum, and B. longum. We found that thepresence of free fatty acids in the medium inhibits the growth of Bifidobacterium species to a varyingdegree, with capric (C10:0), oleic (C18:1), and linoleic (C18:2) acids displaying the largest effect. Incomparison, free fatty acids did not affect the growth of Escherichia coli. When fats were added as amixture of mono- and diacylglycerols, the inhibitory effect on Bifidobacterium growth was abolished.
