Pea albumin extracted from pea (Pisum sativum L.) seed protects mice from high fat diet-induced obesity by modulating lipid metabolism and gut microbiota

•Pea albumin potentially reduced high fat diet-induced body weight gain and fat mass.•Pea albumin improved high fat diet-induced insulin resistance and hepatic steatosis.•Pea albumin regulated lipid metabolism in white adipose tissue and reduced adipocyte size.•Pea albumin selectively promoted the growth of beneficial gut bacteria (Akkermansia, Parabacteroides etc.).
