1. Bamboo shoots are cold and astringent, contain more crude fiber, and are easy to accelerate gastrointestinal peristalsis, so they are extremely unfavorable to patients with gastric ulcer, duodenal ulcer and gastrorrhagia, and are not suitable for chronic gastroenteritis patients to eat bamboo shoots.

2. Bamboo shoots contain nutrients needed by human body, but at the same time they also contain oxalate which is not used by human body. Patients with urinary system diseases and stones are not suitable for eating. Because oxalate contained in bamboo shoots combines with calcium in other foods to form insoluble calcium oxalate, which aggravates the disease.

Children should not eat bamboo shoots. Children are minors in the growth and development period, and the growth of bones requires a lot of calcium. Oxalic acid will affect the body's absorption of calcium.

4. In order to reduce the influence of oxalate on human body, bamboo shoots should be boiled in boiling water for 5 ~ 10 minutes, and most of oxalate and astringency will be removed after pyrolysis, and then cooked with other foods after taking out. In addition, when cooking, cut off the tips and lower parts of bamboo shoots, which is easy to ripen and taste.
