Sea cucumber can be eaten by children, but it is recommended that children under 3 years old should not eat it. Sea cucumber is rich in nutritional value and contains a large amount of DHA, which is beneficial to brain development and intelligence, and also contains a variety of essential amino acids, minerals and collagen, so it is beneficial for children to eat sea cucumber appropriately. However, it is not recommended for children under 3 years old because the gastrointestinal function of children at this stage is still immature and eating sea cucumber may cause indigestion. In addition, although children over 3 years old can eat sea cucumber, it is not recommended to eat too much at one time, so as to avoid the burden on the gastrointestinal tract and cause indigestion.
