Zinc is an important mineral for many functions of our body - down to the very core structure of our cells.
Zinc is integral to the synthesis of RNA and DNA, the genetic material that controls cell growth, division and function.
Men require 11 milligrams of zinc per day while women need a bit less or 8 milligrams a day. These amounts can usually be obtained from the diet by eating foods such as protein-rich meats, fish and poultry.
Dairy products, beans and nuts are good sources of zinc.
Adequate zinc is important in the production of lymphocytes, the specialized white cells in the immune system that help defend against foreign invaders.
Zinc deficiency leads to impaired immunity and decreased resistance to many bacterial, viral, fungal and paracitic invaders. Recovery from illness takes longer when zinc levels are low.
