Lots of people think of pineapple as a summertime treat, however, fresh, sweet pineapple is available all year round with lots of healthy benefits. Pineapples are good sources of vitamin C, B6, thiamine, manganese and fiber. They have zero fat and cholesterol as well.
I love using pineapples in meat marinades, they are an excellent tenderizer as they contain the enzyme bromelain that digests protein. This same enzyme is also found in kiwi and papaya and causes gelatin to break down. The canning process destroys this enzyme, which is why only canned pineapple is used in congealed desserts.
When bromelain is used as a natural supplement it is said to aid with digestion and ease inflammation. With all the tenderizing effects of pineapple, don't soak seafood in it very long, the texture will turn mushy.
