The almond, which we think of as a nut, is actually the seed of the fruit from the almond tree. The almond is related to the peach, but the fruit toughens into a leathery coat, called the hull, which contains the shell and the edible kernel. Unlike the peach pit, the almond kernel is not only edible, but also quite nutritious. The flavonoids found in almond skins team up with the vitamin E found in their meat to more than double the antioxidant punch either delivers when administered separately, shows a study published in the Journal of Nutrition.
