Many mothers have the concern that their babies are vitamin deficient during their growth and development. How can you tell if your baby is vitamin deficient? Here we will give you some symptoms of vitamin deficiency in babies so that mothers can take better care of their babies. If the skin is dry, the respiratory tract is easy to be infected, the eyes are dry, photophobic, tearful, and find that the vision is gradually blurred, there is a lack of vitamin A.

How to regulate vitamin D deficiency? Vitamin D can regulate the body’s calcium and phosphorus metabolism and promote the normal growth of teeth and bones. Vitamin D deficiency can manifest as active rickets, unclosed fontanelle, softened skull, chicken chest, sweating and sour smell. In addition, the child cries, has no appetite, and has “X” or “O” shaped legs. It is reasonable to say that this condition is generally related to calcium deficiency, but how can a child with an adequate supply of calcium also suffer from rickets? It turns out that after the body ingests calcium, it is absorbed from the intestines into the blood, and then transported by the blood to the bone end, thus supplying the raw material for bone calcification. This series of processes must have the synergistic effect of vitamin D to complete successfully. Without vitamin D, calcium cannot be absorbed by the body even if it is eaten in large quantities. For children with vitamin D deficiency, they can take cod liver oil, which contains a large amount of vitamin D. In addition, ultraviolet light is the most abundant source of vitamin D. Children with vitamin D deficiency can often get sunlight, which allows the skin to synthesize its own vitamin D. Eat more calcium and vitamin D containing foods, such as fish, meat, eggs, milk and beans. What is the relationship between vitamin B6 deficiency and diet? Why do some infants have vitamin B6 deficiency? 1. Vitamin B6 is found in human milk or cow’s milk and cereals. If the heating time is too long, vitamin B6 is destroyed; 2. Diseases of intestinal malabsorption can cause vitamin B6 deficiency; 3. Application of antagonists of vitamin B6 such as isoniazid, penicillamine, cycloserine and other drugs.
