Minerals Although
most minerals take up only about 3-4% of our weight,we cannot survive
without them.Exactly how many minerals work,or how much of each is needed,is
still a subject of controversy.Some such as potassium,are needed in fairly
large amounts,while others,such as iodine,are needed in such tiny doses
that they are known as 'trae elements". |
