Getting old is inevitable. Try as we might to find some sort of fountain of youth, the battle against time is a losing one. Hair will gray, wrinkles will form, and muscle loss will occur. But, insofar as that last one is concerned, there may be a way to slow down at least this part of the aging process.

A study from Johns Hopkins School of Medicine points to selenium deficiency as a possible contributor to accelerated muscle loss. Selenium plays a role in protein synthesis, maintaining muscle mass, immune function and neutralizing free radicals. Because many old people fail to consume adequate amounts of this mineral, it may contribute to a decrease in strength, muscle balance and overall mobility.

Most multi-vitamins contain selenium, and it of course can also be sourced from protein-rich foods. However, it is important to note that consuming too much selenium can actually be deadly, which is why you should speak to a doctor before changing your diet to purposely include more of this mineral.
