Dietary Fat's Impact on Gut Flora

"An oleic acid (olive oil) supplement prevented the increases in E. coli and the declines in Bifidobacteria caused by the high fat diet. An omega-3 polyunsaturated fat supplement also increased the number of beneficial Lactobacillus species and prevented the increase in Enterobacteriales induced by high fat diet. This study suggests that fatty acids generally thought to be healthful – oleic acid found in olive oil, and omega-3 fatty acids found in fish, generally reduce the number of potential pathogens (the E. coli containing group Enterobacteriales) and increase the number of protective species (Lactobacillus and Bifodobacteria) in line with the expectations of the Nutrient Signaling model."
