02 Aug 2017 --- A component in green tea could have beneficial effects on memory, brain insulin resistance and tackling obesity, according to a study published online in The Federation of American Societies for Experimental Biology (FASEB) Journal. The study, which involved mice, suggests that epigallocatechin-3-gallate (EGCG), the most abundant catechin and biologically active component in green tea, could alleviate high fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment.
