Contrary to popular belief, the pineapple did not originate in Hawaii but in South America! The fruit was taken to Europe where it was named by explorers who thought it resembled a pinecone. One serving (2 slices, 112g) of pineapple has only 60 calories and provides an excellent source of vitamin C and manganese. Fresh pineapples are the only known source of bromelain, an enzyme whose anti-inflammatory properties, shown in some studies, may alleviate symptoms of osteoarthritis, making pineapple a healthy food for your joints. Preliminary research shows bromelain may also help heal injuries, reduce inflammation associated with asthma and inhibit the growth of malignant cells in both lung and breast cancer. A nutrient combo including bromelain cut down plastic surgery recovery time by 17% according to the American Society of Plastic Surgeons.
