During fetal development and childhood, the brain requires a range of nutrients to build the nervous system and support cognitive development. According to a new review article published in Nutrients, widespread deficiencies in vitamins C, D, and A, as well as iron, iodine, selenium, zinc, and other nutrients, may contribute to the development of autism.

It is an established fact that pregnant women should supplement with folic acid, as it reduces the risk of the baby developing neural tube defects in the brain and spinal cord. According to a new Canadian study, folic acid supplementation may also reduce the risk of the child developing neurological damage and autistic behavior caused by lead exposure. It is crucial for pregnant women to get enough nutrients to support fetal development. Also, they should try to avoid environmental toxins as much as possible.

Pregnant and breastfeeding women have an increased requirement for vitamin C, which is important both for the development of the fetus and as an antioxidant that protects cells and tissues against damage caused by oxidative stress. There are strong indications that the recommended intake for vitamin C is too low. In addition, pregnant and breastfeeding women who smoke may have an even greater need, according to a population study published in Nutrition Research.
