Pollen is a fine to coarse powder consisting of microgametophytes (pollen grains), which produce the male gametes (sperm cells) of seed plants. The pollen grain with its hard coat protects the sperm cells during the process of their movement between the stamens of the flower to the pistil of the next flower. A variety of producers have started selling pollen for human consumption, often marketed as a healthy food. Like many other foods, pollen contains water, amino acids, proteins, lipids, carbohydrates, minerals, vitamins, enzymes and other micronutrients.
