Scientists have found that even moderate deficiency of the vitamins and minerals required for life may lead to age-related diseases.

Joyce C. McCann, a co-author of the study, and colleagues tested whether selenium-dependent proteins that are essential from an evolutionary perspective are more resistant to selenium deficiency than those that are less essential.
They discovered a highly sophisticated array of mechanisms at cellular and tissue levels that, when selenium is limited, protect essential selenium-dependent proteins at the expense of those that are nonessential.
They also found that mutations in selenium-dependent proteins that are lost on modest selenium deficiency result in characteristics shared by age-related diseases including cancer, heart disease, and loss of immune or brain function.
The study was published online in the FASEB Journal.
