Although the substance aluminum (as we say in the U.S.) is the most abundant of all the metallic elements in the Earth's crust, it does not occur in metallic form in nature; instead it exists in compounds found in almost all rocks as well as in plants and animals.

Sample of aluminum metal. Aluminum is the second most abundant metallic element in the Earth's crust after silicon, yet it is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years.

Humans don't require aluminium, and yet it enters our bodies every day - it's in the air we breathe, the water we drink, and the food we eat. While small amounts of aluminium are normally present in foods, we are responsible for the major sources of dietary aluminium: food additives, such as leavening, emulsifying and colouring agents.
