Over the past four decades, the prevalence of asthma has markedly increased among the developed countries and specially for those countries transitioning to their lifestyle. It has been assumed that these increases are a consequence of changing due to environmental and/or behavioral factors. The modification of dietary habits (ie, decreased intake of fruits/vegetables and increased intake of “Westernized” processed foods) and decreased intake of antioxidant vitamins due to a decrease in sun exposure and fatty acids and as well as decreased circulating levels of vitamin D, and might have been anticipated to explicate the rise in asthma prevalence. The aim of this article was to explore whether there is an association between maternal diet during pregnancy and development of atopic disorders like asthma in childhood or not.
