Food as Medicine: Pineapple (Ananas comosus, Bromeliaceae) 

By Jenny Perez
The pineapple fruit became a luxurious status symbol outside of its native South America and a prized commercial commodity throughout the Pacific Islands. It also has a long history of use in traditional medicine systems throughout South America. All parts of the pineapple plant, including the fruit, have been used to regulate blood sugar, as a diuretic, and more. In modern times, the uses of pineapple have expanded as clinical research investigates bromelain, an enzyme present in many parts of the plant with possible benefits for osteoarthritis, periodontitis, and cardiovascular disease.
