APPLE PEELS KEEP MUSCLES STRONG
Apple peels contain a substance that may ward off muscle atrophy and promote muscle growth, according to a University of Iowa study.
“Muscle atrophy causes big problems. It’s also very common — it affects most people at some point in their lives, during illness or aging. But, there's no medicine for it,” notes Dr. Christopher Adams, senior author of the study. “We studied muscle gene activity in people with atrophy and used that information to find chemicals that might block atrophy. One of those chemicals was especially interesting. It’s called ursolic acid and it’s particularly concentrated in apple peels.
“The old saying goes that ‘an apple a day keeps the doctor away.’ So, we tested ursolic acid in mice, and found that it increased the size and strength of their muscles,” Adams adds. “It did this by helping two hormones that build muscle: insulin-like growth factor-1 (IGF1) and insulin. Because ursolic acid increased muscle, it reduced muscle atrophy. Surprisingly, it had some other beneficial effects in mice: for example, it reduced body fat, and lowered blood glucose and cholesterol.”
