Children can eat loach, as long as it is cooked, without worrying about long parasites. It is especially suitable for people with weak body, spleen and stomach deficiency and cold, malnutrition and night sweats in children, which is helpful for the growth and development of the baby. Misgurnus anguillicaudatus should not be eaten with dog meat. Dog blood is very similar to loach: people with yin deficiency and fire are forbidden to eat. Crabs and loaches are very similar: they have just the opposite functions and should not be eaten together. Hairy crabs and loaches are very similar: they will be poisoned when eaten together.
