Pineapple

Pineapples are another food, like papayas, that contains an enzyme that breaks down proteins. In the case of pineapples, the enzyme is bromelain. In addition to making pineapple a good meat tenderizer, bromelain helps block some metabolic products that contribute to inflammation, making it a good anti-inflammatory. Isolated bromelain has been used to treat sports injuries, digestive problems, swelling, and other problems involving inflammation. Its action on proteins has also been found to reduce blood clots, especially in arteries.
Pineapple is a good source of manganese, vitamin B1, and vitamin C.
