HEALTH BENEFITS OF PINEAPPLES
Pineapples are know to be a Digestive Aid and are Naturally Anti-Inflammatory
Fresh pineapple is rich in bromelain, a group of sulfur-containing proteolytic (protein-digesting) enzymes that not only aid digestion, but can effectively reduce inflammation and swelling, and has even been used experimentally as an anti-cancer agent. A variety of inflammatory agents are inhibited by the action of bromelain. In clinical human trials, bromelain has demonstrated signifcant anti-inflammatory effects, reducing swelling in inflammatory conditions such as acute sinusitis, sore throat, arthritis and gout, and speeding recovery from injuries and surgery. To maximize bromelain's anti-inflammatory effects, pineapple should be eaten alone between meals or its enzymes will be used up digesting food. Bromelain is found in both the flesh and stem of pineapple.
Antioxidant Protection and Immune Support
Vitamin C is the body's primary water-soluble antioxidant, defending all aqueous areas of the body against free radicals that attack and damage normal cells. Free radicals have been shown to promote the artery plaque build-up of atherosclerosis and diabetic heart disease, cause the airway spasm that leads to asthma attacks, damage the cells of the colon so they become colon cancer cells, and contribute to the joint pain and disability seen in osteoarthritis and rheumatoid arthritis. This would explain why diets rich in vitamin C have been shown to be useful for preventing or reducing the severity of all of these conditions. In addition, vitamin C is vital for the proper function of the immune system, making it a nutrient to turn to for the prevention of recurrent ear infections, colds, and flu.
Manganese and Thiamin (Vitamin B1) for Energy Production and Antioxidant Defenses
Pineapple is an excellent source the trace mineral manganese, which is an essential cofactor in a number of enzymes important in energy production and antioxidant defenses. For example, the key oxidative enzyme superoxide dismutase, which disarms free radicals produced within the mitochondria (the energy production factories within our cells), requires manganese. Just one cup of fresh pineapple supplies 128.0% of the DV for this very important trace mineral. In addition to manganese, pineapple is a good source of thiamin, a B vitamin that acts as a cofactor in enzymatic reactions central to energy production.
Anti-Tumor Compounds Found in Pineapple Stems
Two molecules found in pineapple stems have shown anti-tumor activity in research done at Australia's Queensland Institute of Medical Research (QIMR). One of the molecules, called CCS, blocks the Ras protein, which is defective in approximately 30% of all cancers, while the other molecule, CCZ, stimulates the immune system to target and eliminate cancer cells.
