Bromelain is a protein-digesting enzyme present in the pineapple fruit's stem and core. This digestive enzyme can be found in a variety of supplements, health treatments, and skin care items. Bromelain exfoliates and rejuvenates the skin. Bromelain must first be isolated from pineapple before it can be used. There are several methods for doing this; all involve using enzymes to break down parts of the pineapple until only the bromelain remains. Pineapple has many health benefits. It helps fight inflammation and bacteria that cause infection. Eating pineapple can help reduce pain from arthritis, gout, and other conditions caused by inflammation. Pineapple is also good for your teeth. The enzyme bromelain removes stains from your tooth enamel. This makes pineapples a good food source if you're trying to get whiter teeth! Pineapple has been used for medicine for hundreds of years. The Hawaiians made pineapple juice into an infusion they called "ilima", which means "beneath the surface" or "under the skin" in Hawaiian. They used it to treat wounds and abrasions, diarrhea, and dysentery. Modern scientists have confirmed what the Hawaiians knew all along: Pineapple is good for you!
