Bean and other seed shoots are also known as sprouts (新芽). The dry bean seeds contain a store of nutrients just waiting to be released when they sprout. Under the right conditions they will germinate (发芽)。 As they grow, the food value of the seeds is multiplied into vitamins, minerals (矿物质) and other nutrients. This happens almost overnight!
It is easy to grow your own sprouts, but you need to buy your seeds from supermarkets or health food stores. Seeds for planting in the garden are often powdered with chemicals, so when becoming sprouts they are not safe to eat.
Try growing sprouts from a variety of beans and seeds. You will find different sprouts at different stages. Bean sprouts are best when they are about three centimeters long. Wheat and sunflower sprouts taste best when the sprouts and the seeds are of the same length. If the sunflower sprout is too long it leaves a funny stinging feeling in the throat after eating. Alfalfa sprouts are best when their small leaves are well developed. Pea and soybean sprouts are good long or short.
If you leave your sprouts in filtered sunlight for a few hours, the leaves will turn green as chlorophyll (叶绿素) is added. Eating sprouts with green leaves benefits your blood, cells, and the digestive system.
