Do you know that when you remove the skin of an orange you are also removing nutrients that could lower bad cholesterol? On the other hand, the juicy sweet pulp is renowned for its healthy dose of vitamin C that helps to increase the body’s immunity.
One fresh orange supplies about 90 per cent of our daily vitamin C requirement. In our body, vitamin C is the main water-soluble antioxidant responsible for prevention of free radicals that damage cellular structures, especially in areas where cellular turnover is very fast such as in the digestive system. The high dose of vitamin C in orange juice may give us protection from oesophageal, mouth, stomach and colon cancers.
Men who are overweight and have high blood pressure need to eat more food with vitamin C. A Finnish study reports that getting enough vitamin C in the diet may decrease the risk of getting a stroke. Vitamin C works more effectively with folate, potassium, carotenoids and flavonoids to support a healthy heart. All these are nutrients in oranges that are important in regulating the good HDL and bad LDL cholesterols and blood pressure levels.
Similar to apple juice, drinking half to a litre of orange juice daily may lessen the risk of calcium oxalate kidney stones. Vitamin C is not only good for protecting against colds and ear infections, it is also associated with decreased severity of inflammatory circumstances related to asthma, rheumatoid arthritis and osteoarthritis. Vitamin C in orange also prevents bruising, aids in wound healing and increases iron absorption.
Oranges are citrus fruits with finely textured skins. For years, the Chinese have been using orange peel, its seeds and the leaves to treat various aliments, especially in illnesses relating to cough and phlegm.
Scientists have identified the active nutrients as flavonoids and polyphenols. They are concentrated mainly in the outer and inner white pulp of the peel.
The phytochemicals are anthocyanins, hydroxycinnamic acids, hesperetin, naringenin, and a mixture of polyphenols. Flavanone herperidin has especially been the well-studied component. Herperidin is capable of lowering blood pressure and cholesterol levels. It also has strong anti-inflammatory properties that benefit the asthmatic. If you are looking for food that helps to alleviate these problems, you must eat oranges together with the inner white pulp and not just the juice.
Orange peels and Chinese mandarin oranges (tangerines) are rich in another phytonutrient known as polymethoxylated flavones (PMF). PMF may lower LDL (bad cholesterol) more effectively than some prescription drugs. It also has no side effects.
