31 May 2018 --- Mothers who eat omega-rich fats from oily fish may help their children maintain a healthy weight for the entirety of their lives, a study has found. The research, published in Microbiome, found that the maternal fatty acid status persistently restructures the offspring’s microbiota and the associated metabolic homeostasis related to obesity. A diet that was higher in omega 6 fats than omega 3 contributed to a leaky gut in the kids, potentially contributing to weight gain. The findings further the call for omega 3 supplementation during pregnancy.
