6 Fruits And Vegetables You Should Never Peel

It's time to put down the peeler and stop removing the edible skins from your fruits and vegetables.

The colourful peels on the outsides of your produce are often the most concentrated source of vitamins, minerals, and antioxidants.

Here are six fruit and veges you should know about:

  1. Apples
    Peeling an apple won’t really rob you of a whole lot of vitamin C, but you will lose out on pectin—a soluble fiber that can help keep you regular and lower your “bad” LDL cholesterol and blood sugar.

  2. Carrots
    Carrots are rich in polyacetylenes—a chemical compound currently being researched for its potential to kill human cancer cells in test tubes. They may have antifungal, antibacterial, and anti-inflammatory effects, too. But these compounds are concentrated just below the skin—so either leave your carrot skins on or go easy with the peeler and remove only a thin strip.

  3. Potatoes
    Gram for gram, potato skins have more fiber, iron, and folate than potato flesh. When planting potatoes, choose deeply pigmented purple potatoes and the skin becomes even more important. Researchers at the University of Maine say the skins of these potatoes contain 5 to 10 times more antioxidants than the flesh.

  4. Cucumbers
    Peeled cucumbers have less calcium, magnesium, phosphorous, potassium, vitamin A, and vitamin K than their fully intact counterparts. Plus, nearly all of cucumber’s fiber comes from the peel—the inner flesh is mostly water.

  5. Eggplant
    Eggplant skin is packed with an antioxidant called nasunin. The compound hasn’t been extensively researched on its own, but one animal study found in the U.S. National Library of Medicine and National Institutes of Health suggests that it could be important in maintaining healthy brain tissue. Plus, nasunin is part of a larger family of antioxidants known as flavonoids. The more flavonoids you eat, the less likely you are to gain weight over time.

  6. Grapes
    The skins are where you’ll find all of red grapes’ resveratrol—the phytochemical that seems to benefit heart and brain health and that’s been shown to slow cancer growth in cell and animal studies.
