What are the symptoms of zinc deficiency in infants?

Zinc deficiency is a common nutritional issue in infants and young children, which may lead to a variety of symptoms. 1. **Growth retardation**: Zinc deficiency in infants can reduce protein synthesis in the body, resulting in delayed development and significantly shorter height compared to peers. 2. **Loss of appetite**: Zinc deficiency can slow down the renewal of taste bud cells and reduce taste sensitivity, leading to symptoms of anorexia in infants. This typically manifests as decreased appetite, reduced food intake, and indigestion. 3. **Weakened immune system**: Zinc is an essential trace element for the human body. If infants lack zinc, it can lead to weakened immunity,表现为 frequent colds, fever, and recurrent respiratory tract infections.
