Foods are ___________ composed of elements from the periodic table

There are 6 elements found in almost all foods. These elements are carbon, hydrogen, nitrogen, phosphorus, and sulfur.

There are also 5 elements found as salts (dissolved). They are sodium, magnesium, chlorine, potassium, and calcium.

There are 3 trace elements, which means they are found in very small amounts in organisms. They are iron, copper, and zinc.

All of these, with the exception of oxygen, carbon, and hydrogen, are called "minerals".

These elements all produce what are called "biomolecules" or "biochemicals". The four primary biomolecules found in the human body are lipids (fats/oils), carbohydrates, proteins, and vitamins.
