Minerals Notes….

 Minerals are elements other

than carbon, hydrogen,

nitrogen, and oxygen which are needed for good health

 Minerals are micronutrients.

 Minerals are inorganic

substances.

 Minerals must be present in the soil in which food is grown in order to be incorporated

into the food

 We also obtain some minerals from the

water we drink, but the amounts vary widely

 Mineral availability and absorption is also

affected as foods are cooked, processed and refined, and many naturally occurring

minerals in food are removed.

 Minerals work in combination with each other and with other nutrients, so

imbalances of any mineral can cause health problems – too little of any

essential mineral can lead to deficiency diseases, and too much of any mineral can be toxic

Essential Minerals

 Essential minerals are sometimes divided

up into major minerals (macrominerals) and trace minerals (microminerals)

 These two groups of minerals are equally important, but trace minerals are needed

in smaller amounts than major minerals

 The amounts needed in the body are not

an indication of their importance

Major minerals

 Major minerals are those needed

in amounts greater than 100 mg per day

 Major minerals are sulfur, calcium, phosphorus, sodium, potassium,

chlorine, and magnesium

Minor minerals

 The minor minerals are needed in

trace amounts - less than 100 mg per day

 These metal ions are incorporated

into enzymes, hormones, and other molecules.

 They include iron, fluoride, zinc,

copper, selenium, manganese, iodine, molybdenum, chromium, and cobalt

Electrolytes

 Minerals in the body that carry an electric charge

 Function: regulate the amount of water in your body, blood pH, muscle action

 Electrolytes can be measured by

laboratory studies of the blood serum

 The electrolytes are sodium, chlorine and potassium

Minerals: macro, trace, non-essential trace, & electrolytes
