Numerous research studies support the saying “An apple a day keeps the doctor away.” Apples (Malus sp., Rosaceae) contain a wide variety of vitamins and minerals vital for good health. It’s not just the flesh of an apple that provides nutrients, but the polyphenols in apple skins have powerful documented health benefits.
According to one study in Finland, people who ate five apples a week had the world’s lowest rate of diabetes, heart disease, and cancer.
An apple with skin ON contains 50% MORE phytonutrients than a peeled one!
Apple skins have exceptionally high concentrations of antioxidants. They also contain compounds (triterpenoids) with significant anti-cancer capabilities. Particularly so, when it comes to preventing liver, colon and breast cancer. Research shows apple peels and extracts may also help lower cancer risk for several types of cancer.
With so many health benefits, it’s worth exploring the pros and cons of eating apple skin.
Is Apple Skin Safe to Eat?
It depends on how the apples are grown and how well they are washed. If you grow your own without chemicals, there’s no issue of course. Unfortunately, chemically grown apples absorb the sprays into the flesh, not just on the skin surface.
In the 2019 EWG Shopper’s Guide to Pesticides in Produce, conventionally grown apples again made it into the top 5 most contaminated fruit and vegetables in their ‘Dirty Dozen’ list. Over 90% of apple samples tested positive for two or more pesticide residues. Apple skins contain higher nutrient value than flesh. However, they have also tested for a greater concentration of toxic chemicals.
