Tomato, carrot, and orange peels are rich in antioxidants that protect cells from damage by free radicals, which lead to cancer and disease. The skins of fruits and vegetables contain many vitamins, fiber, and minerals such as potassium and magnesium, which have many health benefits, but are often peeled away due to concerns about chemicals. Utilizing clean fruit peels to prepare dishes helps increase flavor and gain more nutritional value, including cancer prevention.
Apple peels provide abundant vitamins and minerals, especially vitamin C and potassium, which are essential for overall health. This fruit peel has high fiber content, supporting digestion and weight control. They also contain antioxidants and plant compounds such as quercetin, catechins and chlorogenic acid that contribute to the prevention of chronic diseases such as cancer, diabetes, Alzheimer’s, and dementia.
Citrus peels (oranges, lemons, grapefruits) are fragrant and contain high amounts of fiber, vitamins and antioxidants. Compared to the flesh, the peel of citrus fruits contains more fiber, supporting digestion and enhancing intestinal health. The peels of these fruits are rich in vitamin C and many different bioflavonoids, which have anti-inflammatory and immune-boosting properties. Antioxidants in citrus peels have the ability to fight free radicals, reducing the risk of chronic disease.
Tomato peels are rich in the antioxidant lycopene, 2.5 times higher than the pulp, and are a good source of minerals including zinc, manganese, and copper. According to a 2018 meta-analysis by the University of Illinois, lycopene and other plant pigments in tomatoes fight the development of cancer due to their antioxidants. Men who eat more tomatoes, raw and in sauce, have a lower risk of developing prostate cancer.
Carrot peels are rich in fiber, antioxidants like beta carotene and polyacetylenes, and other beneficial phytonutrients. Beta-carotene converts to vitamin A in the body which is needed to maintain vision, skin, and immunity. Antioxidants in carrot peels can protect cells from damage by free radicals, potentially reducing the risk of cancer and other chronic diseases.
Potato peels contain higher levels of vitamin C, potassium, folate (vitamin B9), magnesium, and phosphorus than peeled tubers. They also provide fiber, which is good for intestinal health and creates a feeling of fullness, supporting weight loss. Potato peels have antibacterial and antioxidant activities that can fight cell-damaging free radicals. Phenolic compounds in potato peel extract have the ability to hinder fat oxidation and inhibit bacteria, enhancing immunity.
