A waxy substance found in apple peels may promote muscle growth and the prevent muscle wasting that is a hallmark of aging, fasting or illness, a new study in mice suggests.
Mice given the compound, called ursolic acid, became leaner and had lower blood levels of glucose, cholesterol and triglycerides. The findings therefore suggest that ursolic acid may be responsible for some of the overall benefits of healthy eating, the study said.
Further, the results suggest the compound is a promising drug candidate to treat muscle wasting, the researchers said. Currently, there are no drugs for the condition.
