A study published in the Journal Environ. Sci. Pollut. Res. Int. addresses the interaction between heavy metals and depression. This study also supports the role of dietary vitamin intake in protecting the public against depression. Further studies are needed to reduce the risk of depression by heavy metals and to determine more comprehensively the effects of daily dietary vitamin intake on depression. In this study it was determined that a doubling of serum cadmium was associated with a 21% increase in depression whereas twofold increases in daily vitamin B1, B3 and vitamin A intakes reduced the risk of depression by 17%.
