Pineapple juice is a cold and refreshing drink made from fresh or canned pineapple pulp. It is rich in vitamins and minerals, in particular vitamin C, manganese and bromine. Pineapple juice is known for its anti-inflammatory properties and is often consumed to relieve headaches, colds and coughs. It is also considered to be a digestive food, because it contains a natural enzyme called bromelain which helps to decompose proteins and facilitate digestion.
