This study, conducted by American and Ecuadorian researchers, investigated the effects of micronutrient deficiencies on the immune response and respiratory infections in elderly Ecuadorians. 352 elderly were involved in this study. Several important micronutrients for immune function were measured in the participants’ blood. The results showed that micronutrient deficiencies were associated with a high risk of infections due to an impaired immune function. More details can be found in the study.
