While it’s true that there are nutrients in the skin of an apple, there is also the same level of nutrients found in the meat as well. Removing the skin only reduces the nutrient count by a few grams of fiber and a few milligrams of calcium and potassium, which really doesn’t make that much of an impact. If you are faced with a fussy eater that just refuses to eat anything with the skin, these devices are a great tool to have on hand. Plus, when preparing the fruit to make sauce, pies, or cobblers, it is important that you are able to remove the skin before cooking. Besides, no one ever eats pie for positive health benefits, so removing the nutrients from the skin shouldn’t be a big issue in the case of baking!
