Oranges are one of the most widely consumed fruits worldwide, known for their juicy pulp and vibrant flavor. However, despite their popularity, a significant part of the orange, its peel, is often discarded. Have you ever wondered why we are discouraged from eating the peel of an orange, unlike some other fruits where the skin is not only edible but also nutritious? The answer lies in the composition and properties of the orange peel, which, although not toxic, is not particularly beneficial or safe for human consumption in large quantities.
