Broccoli is an edible green plant in the cabbage family (family Brassicaceae, genus Brassica) whose large flowering head and stalk is eaten as a vegetable. The word broccoli comes from the Italian plural of broccolo, which means “the flowering crest of a cabbage”, and is the diminutive form of brocco, meaning “sprout”.
A 100 gram reference serving of raw broccoli provides 34 calories and is a rich source (20% or higher of the Daily Value, DV) of vitamin C (107% DV) and vitamin K (97% DV) (table). Raw broccoli also contains moderate amounts (10–19% DV) of several B vitamins and the dietary mineral manganese, whereas other micronutrients are low in content (less than 10% DV). Raw broccoli is 89% water, 7% carbohydrates, 3% protein, and contains negligible fat (table).
