Does the old advice “An apple a day keeps the doctor away” hold true? It depends upon how you look at the data. A 2011 study found that consumption of apples and pears might prevent strokes and one in 2012 found that apple consumption significantly lowered bad cholesterol levels in middle-aged adults.In 2013, the BMJ published a study as part of its humorous Christmas issue comparing the effects of prescribing everyone in the UK over age 50 either an apple or a statin a day. The study concluded that both interventions would be similarly effective.
Now as far as office visits were concerned, there are no reported statistically meaningful difference in visits to the doctor for daily apple eaters in the analysis. But some studies have found that an apple a day kept the pharmacist away, meaning those that ate an apple a day reported taking fewer to no medication.
