"... the average human body contains something on the order of 4 trillion cells. Between 60-70% of those cells should replace themselves every 6 months. That means that about 15 billion cells in your body are replacing themselves every day. Each of those cells has a nucleus in it that contains your DNA and each strand of DNA requires at least 45 separate minerals to replicate itself properly. The numbers quickly become more than the average person wants to spend too much time thinking about, but the point is that the nutrients in your food which is what your body uses to build itself with constantly have a key role to play your overall health."
