Pineapple in many different research studies showed it is a great anti inflammatory agent. It is loaded with bromelian which is an enzyme that has been used to treat problems such as arthiritis, heart disease, cancer, injuries. The Planta Medical research journal published a study that discovered that bromelain worked better than drug 5- fluoracil in treating cancer in an animal study. Note that bromelain is more in the stem of the pineapple so make sure to always eat the stem. Check out master Rorion gracie making his pineapple juice.
