Pineapple is high in manganese, a mineral that is critical to development of strong bones and connective tissue. A cup of fresh pineapple will give you nearly 75% of the recommended daily amount. It is particularly helpful to older adults, whose bones tend to become brittle with age.
Bromelain, a proteolytic enzyme, is the key to pineapple's value. Proteolytic means "breaks down protein", which is why pineapple is known to be a digestive aid. It helps the body digest proteins more efficiently.
Bromelain is also considered an effective anti-inflammatory. Regular ingestion of at least one half cup of fresh pineapple daily is purported to relieve painful joints common to osteoarthritis. It produces mild pain relief. In Germany , bromelain is approved as a post-injury medication because it is thought to reduce inflammation and swelling.
Orange juice is a popular liquid for those suffering from a cold because it is high in Vitamin C. Fresh pineapple is not only high in this vitamin, but because of the bromelain, it has the ability to reduce mucus in the throat. If you have a cold with a productive cough, add pineapple to your diet. It is commonly used in Europe as a post-operative measure to cut mucus after certain sinus and throat operations. Those individuals who eat fresh pineapple daily report fewer sinus problems related to allergies. In and of itself, pineapple has a very low risk for allergies.
Pineapple is also known to discourage blood clot development. This makes it a valuable dietary addition for frequent fliers and others who may be at risk for blood clots.
An old folk remedy for morning sickness is fresh pineapple juice. It really works! Fresh juice and some nuts first thing in the morning often makes a difference. It's also good for a healthier mouth. The fresh juice discourages plaque growth.
