Could an Apple a Day Help Keep the Pharmacist Away?
Study finds no effect on doctor visits, but a slight decrease in need for prescription meds
-- Robert Preidt
MONDAY, March 30, 2015 (HealthDay News) -- Munching each day on a McIntosh, Granny Smith or other apple might not keep the doctor at bay, but a new study finds apple eaters are less likely to need a prescription medicine.
The study, funded by the U.S. National Institutes of Health, looked at data from nearly 8,400 people who took part in federal health surveys between 2007 and 2010.
Of those participants, 753 (9 percent) were apple eaters -- at least one small apple per day -- and the rest were non-apple eaters.
Apple eaters were slightly less likely to use prescription medications, reported a team led by Matthew Davis, of the University of Michigan School of Nursing in Ann Arbor.
But apple consumption was not linked to other health markers -- things such as the number of annual doctor visits a person made, frequency of overnight hospital stays, or visits to a mental health professional.
And the study wasn't designed to find that apple consumption caused any uptick in health. Davis and colleagues found that people who ate at least one apple each day also tended to have higher levels of education and were less likely to smoke.
Overall, the findings "suggest that the promotion of apple consumption may have limited benefit in reducing national health care spending," the study authors concluded.
One expert agreed that eating apples might be at least a signal of a healthier lifestyle, however.
"This study does leave open the possibility that apple lovers do have healthier lifestyles in general, which could explain the association between apple-eaters and fewer prescription medications," said Erin Keane, an outpatient dietitian at Lenox Hill Hospital in New York City.
She also pointed to the apple's nutritional goodness.
"Apples are a good source of soluble fiber, vitamin C and certain flavonoids, as are many fruits and vegetables," Keane said. "For these reasons, apples help decrease our [bad] LDL cholesterol, boost our immune system, and provide us with anti-cancer compounds," she added.
"We should take advantage of this sweet treat and use it in place of dessert or as part of a snack with some nuts or low-fat cheese to get us on the right path towards health," she believes.
The study was published online March 30 in the journal JAMA Internal Medicine.
