The pineapple (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae. Raw pineapple pulp is 86% water, 13% carbohydrates, 0.5% protein, and contains negligible fat. In a 100-gram reference amount, raw pineapple supplies 209 kilojoules (50 kilocalories) of food energy, and is a rich source of manganese (44%) and vitamin C (58%), but otherwise contains no micronutrients in significant amounts.
