The following foods or medications for children can have a good effect on strengthening resistance: First, children can be given more fish, shrimp, eggs and milk. Because fish, shrimp, eggs and milk are high-quality proteins, they help children’s immunity and do not cause significant hyperlipidemia in children. Second, children can eat more yams. Yam has a good nourishing effect on the spleen and stomach. When children’s spleen and stomach functions improve, their ability to transport qi and blood will be enhanced and their resistance will be improved.
