"The peach and plum in the city are sad about the wind and rain, and the spring is in the creek and the cauliflower." Shepherd's cabbage is one of the most representative plants in spring.

Spring bamboo shoots
"If you don't eat spring bamboo shoots, you must know the meaning of spring"?
Spring bamboo shoots are grasses and herbaceous plants, and their edible parts are primary, fat, short and strong buds or whips.
Fertile, loose, well-drained soil, plenty of sunlight, and proper humidity are all conducive to the smooth growth of shoots.

Spring bamboo shoots are rich in dietary fiber, of which the content of insoluble dietary fiber is as high as 2.8g/100g, which can promote gastrointestinal motility, promote bowel movements, prevent constipation, and be beneficial to intestinal health. However, because it has a large amount of dietary fiber, it is not very friendly to people with stomach problems or poor digestion, so remember to eat less.
Spring shoots are also high in potassium. Adequate potassium intake not only helps regulate blood pressure, but also helps reduce neuromuscular tension and relieve fatigue.
Spring bamboo shoots are rich in antioxidants, which can remove excess free radicals from the body and prevent cancer and blood vessel damage.
Fresh spring bamboo shoots are very crisp and tender, but do not eat them raw! Fresh spring bamboo shoots contain cyanide, cyanogenic glycosides, tannins, oxalic acid, ephedrine and other substances, which not only taste bad when eaten raw, but also affect the absorption of minerals, and also increase the risk of kidney stones. However, these ingredients are soluble in water and are not heat-resistant, so be sure to blanch them before eating!
