The enzymes in pineapples also fight free-radical damage and can reduce age spots and fine lines. Pineapple contains a powerful enzyme called bromelain. Bromelain has been shown to be anti-inflammatory as well as a powerful cleanser. It has been used to help relieve pain, swelling, and tenderness due to injuries.
