I love pineapple ! After reading about the health benefits of a fresh, raw pineapple, I started using it for easing the pain when I have the arthritis/joint pain . It is anti-inflammatory, and also is a natural pain reducer, and will help reduce bloating if you have issues with that as well.
Once very important thing is to be sure to get a fully ripe pineapple. If it is even a little green, then it does indeed do the "Drano thing" with your mouth, but when it is totally ripe, this does not occur.
Pineapple is also one of the well-known anti-cancer foods, and is an important part of any anti-cancer diet.
