Apple peel could combat obesity26 June 2012
Consuming apple peel could increase muscle mass and protect against obesity, according to researchers at the University of Iowa in the United States.
The research, which was published in the journal PLoS ONE, studied the effects of ursolic acid – a waxy substance found in apple peel – on mice fed a high-fat diet. Consumption of ursolic acid was found to increase muscle and brown fat mass in the mice studied.
The scientists discovered the mice consuming apple peel to have lower rates of obesity, pre-diabetes and fatty liver disease than those that had not been exposed to ursolic acid.
"From previous work, we knew that ursolic acid increases muscle mass and strength in healthy mice, which is important because it might suggest a potential therapy for muscle wasting," Dr Christopher Adams, the research project’s leader.
"In this study, we tested ursolic acid in mice on a high-fat diet -- a mouse model of obesity and metabolic syndrome. Once again, ursolic acid increased skeletal muscle. Interestingly, it also reduced obesity, pre-diabetes and fatty liver disease.”
