In the context of nutrition, a mineral is a chemical element required as an essential nutrient for organisms to perform functions necessary for life.
If Rocks Created Life They Must Sustain Life!
“Life begets rock, rocks beget life.” Quotes from a Carnegie geologist who makes the case that minerals have evolved over time and may have helped spark life. A team of experts in the field presents this idea in a new NOVA feature Life’s Rocky Start.
Minerals originate in the earth and cannot be made by living organisms. Plants get minerals from the soil. Most of the minerals in a human diet come from eating plants and animals or from drinking water. As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids.
The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. All of the remaining elements in a human body are called “trace elements”. The trace elements that have a specific biochemical function in the human body are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine and selenium.
When something is not working it is always good to go back to the beginning. Recent studies have shown a tight linkage between living organisms and chemical elements on this planet. This led to the redefinition of minerals as “an element or compound, amorphous or crystalline, formed through ‘biogeochemical’ processes. The addition of ‘bio’ reflects a greater appreciation, although an incomplete understanding, of the processes of mineral formation by living forms.
