Fruit peel, or fruit skin is the outer, protective covering in fruits. In general, the skin in some tough-layered fruits such as pomegranate, passion fruit, mangosteen…etc., is known as the rind, while in citrus fruits such as in oranges, it is better termed as peel (zest). Besides its outer cover protect underlying edible portion of fruit from harsh environmental factors as well as micro, and macro organisms, it, indeed, holds some of vital health benefiting constituents such as dietary fiber, and phyto-nutrients that help accomplish overall wellness.
Health benefits of oranges
Most citrus fruits have a good deal of vitamin C, and oranges have high levels even compared to their tangy brethren. Vitamin C, a potent antioxidant, protects cells by scavenging and neutralizing harmful free radicals, according to a 2018 review published in the journal Advances in Analytical and Pharmaceutical Chemistry.
Free radicals are reactive atoms that can form from things such as environmental pollution, cigarette smoke and stress, and exposure to a high level of free radicals may lead to chronic conditions such as cancer and heart disease.
The vitamin C in oranges may also boost a person's immunity to everyday viruses and infections such as the common cold, according to the same review.
Some research suggests that the vitamin C in oranges may be linked with a lower risk of certain cancers.
"The vitamin C in oranges is associated with a reduced risk of colon cancer due to preventing DNA mutations from taking place," Flores said. Studies have shown that about 10 to 15 percent of colon cancers have a mutation in a gene called BRAF.
