How about apples? There’s a saying “an apple a day keeps the doctor away” so they must be really healthy, right?

Unfortunately, a clinical study that compared people that typically ate at least 1 small apple a day vs. those who didn’t concluded that there was no evidence that “an apple a day keeps the doctor away.”

However, many studies show an association between eating apples and a decreased risk of chronic diseases like cardiovascular disease, cancer, and asthma. Apples contain various phytochemicals, many of which have antioxidant and/or anticancer functions.
