Rapeseed and Soy Lecithin As Food Additives Vectors of α-Linolenic Acid: Impacts on High-Fat Induced Adiposity Inflammation and Gut Microbiota in Mice

摘要

Dietary synthetic emulsifiers have recently been shown to promote metabolic syndrome and alter gut microbiota. The effects of natural emulsifiers, such as vegetable lecithin, remain, however, poorly described. Our objective was to evaluate, in mice, the impact of soy and rapeseed lecithin, both rich in essential α-linolenic acid (ALA), when incorporated in high-fat (HF) Western diets on the bioavailability of ALA, as well as on HF-induced adiposity, inflammation and gut microbiota.
