Pineapples are useful in preventing and treating disorders of the Immune System, the Heart and Circulatory System and the Digestive System.
They are useful in treating conditions like sore throats and fevers, and have specific properties which promote healing of soft tissue injuries, breaking down of blood clots and also helping digestive problems
Although they contain some Vitamin C, pineapple is better known for its other qualities. In Hawaii, they eat chunks of juicy pineapple as a delicious cure for digestive problems; we now know that the fresh fruit contains an enzyme, bromelain, which can digest many times its own weight of protein in a few minutes. This is found only in Pineapple. Pineapple juice is also great for sore throats as it contains antibiotic and anti-inflammatory compounds.
Nutrients
Pineapples don’t continue ripening after harvest. When choosing your pineapple look for one that feels heavy for its size, as this is a good guide to quality. The old wives tale of whether you can tug a leaf easily out of the crown, is meaningless and has no bearing on potential flavour.
