The pineapple (Ananas comosus) is a tropical plant and an example of a multiple fruit: multiple, spirally-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit.

Pineapple contains a proteolytic enzyme bromelain, which digests food by breaking down protein. Pineapple juice can thus be used as a marinade and tenderizer for meat.

Pineapple is a good source of manganese as well as contains significant amounts of Vitamin C and Vitamin B1.
