It is well established that proper nutrition is critical to the development of an effective immune system and to enhance the natural immunosurveillance and its effector mechanisms. This enhancement could be mediated either by increasing the frequency and absolute numbers of effector cells or by up-regulation of the cellular mechanisms by which these effector cells carry out their functions. Even in the Western world, large sectors of society often remain undernourished and show suboptimal immune responses, but the relationship between nutrition and immunity is best seen in developing and underdeveloped countries. Although there are many large-scale field studies that investigate the issue of nutrition and immunity, there are relatively few data that go beyond descriptive measurements and directly address how well the immune system functions. This review summarizes interactions between nutrition and immunity and focuses on practical aspects for evaluation of the immune function in the field.
