Docosahexaenoic acid (DHA), one of the major omega-3 polyunsaturated fatty acids, has been shown to yield positive effects in promoting retinal, neuronal, and cognitive health. DHAc an only be obtained through diet, namely from foods rich in omega-3 fatty acids. Unfortunately, there appears to be a downward trend in omega-3 fatty acid intake, such that humans generally receive less of these nutrients than is recommended. This paper first provides a literature review in order to establish the role of DHA in enhancing cognitive function and neuronal health. From here, it critically examines recent nutritional analyses of cafeteria food in U.S.A. schools, and concludes a problematic lack of omega-3 fatty acid containing foods. This paper provides a translation approach to laboratory studies of DHA, looking to bridge the gap between scientific research and the application of nutrition-promoting strategies in school cafeterias.
