When eating fruit, people are accustomed to peeling them. A long-standing habit has led us to believe that peels should be discarded. In fact, numerous studies have confirmed that the peels of fruits and vegetables are more nutritious than the flesh. Not only are the nutritional components in these discarded peels abundant, but they are also more beneficial to the body. Let's take a look at which fruit peels are high in nutritional value.
Fruit peels are a great remedy for diet therapy and health preservation.
Apple peels are antioxidants.
Apple peels are rich in dietary fiber, which aids digestion. Nearly half of the vitamin C in an apple is found in the part just beneath the peel. Research indicates that apple peels have stronger antioxidant properties than the flesh, even more so than many other fruits and vegetables. Many manufacturers have already started extracting active substances from apple peels to develop functional foods.
Grape peels lower blood lipids.
Grape peels contain more resveratrol than the flesh and seeds of grapes. They help lower blood lipids, prevent thrombosis, atherosclerosis, and boost immunity. The flavonoids in purple grape peels, in particular, can also lower blood pressure. Grape peels are also rich in fiber, pectin, and iron. Some have begun to research the use of grape peels in processed foods to treat high cholesterol and diabetes.
Orange peels whet the appetite and resolve phlegm.
Orange peels are rich in various nutrients, such as vitamin C, carotene, and protein, and can be used to make many delicious dishes. Orange peel porridge is fragrant and tasty, and can also treat chest and abdominal bloating or a cough with excessive phlegm. Adding a few pieces of orange peel to meat soup makes the broth fresher and less greasy. Soaking orange peel in water or tea makes for a light, refreshing drink that can also stimulate the appetite, relieve flatulence, and refresh the mind. Orange peel steeped in wine has the effect of clearing the lungs and resolving phlegm. Lemon peels are similar.
Winter melon peels promote urination and reduce swelling.
Winter melon peels not only contain a variety of vitamins and minerals but also multiple volatile components. They can promote urination and reduce swelling and are especially beneficial for diabetics. Therefore, it is best to cook winter melon soup with the peel on.
Cucumber peels help with detoxification.
Cucumber peels contain more cucurbitacins, which are the essence of the cucumber's nutritional value. Eating cucumbers with the peel allows for the full absorption of vitamin C and helps the body detoxify effectively. Additionally, cucumber peels have antibacterial and anti-inflammatory properties. "Fresh Mixed Three Peels," a salad made by blanching watermelon, cucumber, and winter melon peels, is ideal for people trying to lose weight.
Tomato peels prevent cancer.
Lycopene is the most powerful natural antioxidant discovered to date. It can prevent and treat cardiovascular diseases, boost the body's immunity, and prevent cancer. It is most abundant in tomato peels. Furthermore, tomato peels also help maintain intestinal health. Therefore, eating tomatoes with the peel on is the most nutritious way to consume them.
Eggplant peels protect the cardiovascular system.
Eggplant is an excellent food remedy for people with cardiovascular issues, yet most of its nutrients are found in the peel. Peeling the eggplant not only reduces its health value but also causes the iron in it to oxidize upon exposure to air, turning it black and affecting the body's absorption of iron.
After reading the above introduction, don't you think it's a shame to discard these peels? Yes, from now on, we just need to remember to wash them thoroughly when eating fruit. Even if you can't eat them right away, you can still absorb their nutrients through other methods.
