Does an apple a day really keep the doctor away? I hope so, because my trees are groaning with hundreds of these beauties this year.

I decided to see if this saying was true. There was a study published in the Journal of the American Medical Association in 2015 entitled “Association between Apple Consumption and Physician visits.”

“The aphorism, ‘An apple a day keeps the doctor away,’ originated in Wales,” these researchers said. It first appeared in a publication in 1866: “Eat an apple on going to bed and you’ll keep the doctor from earning his bread.” These scientists decided to look at the self-reported diets of 8,728 adults to see if those who ate at least one small apple a day avoided extra trips to the doctor. They found that apple eaters really didn’t visit their doctors less often.

They did find, however, that daily apple eaters tended to use fewer prescription medications, which led one author to comment that “there may be merit to saying, ‘An apple a day keeps the pharmacist away.’ ”

According to a more recent review on this topic by registered dietitian Kristin Sementelli, an apple a day — along with other healthful habits — can go a long way to help keep the doctor away.

Apples are nutrient dense. That means we get a good payment of nutrients for the calories we invest in apples. For just 95 calories in one medium apple, we also get essential nutrients like vitamin C and potassium.

Apples are also known as a good source of soluble fiber — the type that helps lower blood cholesterol levels. Soluble fiber also helps fill a hungry tummy with no extra calories; so foods high in soluble fiber can be effective weight loss tools. Just make sure to eat your apples with the skin; that’s where much of the soluble fiber is.

Apples may guard against diabetes. Naturally-occurring phytochemicals in apples have been implicated as possible disease fighters, according to some research. And apples and other fruits and vegetables are good for our bones.
