A mother's nutritional intake during pregnancy is believed to influence and possibly offer protective effects against the development of allergenic diseases and asthma in children. Maternal intake of vitamin D, vitamin E, and zinc have all been associated with a lower likelihood of wheezing in childhood, suggesting a protective effect. Additionally, maternal intake of omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFAs) has been associated with a reduced risk of development of eczema in childhood and reduced likelihood to for infants exhibit sensitivity to foods in the first year of life.
