Micronutrients - Minerals
Microminerals
- Trace Elements (TE) - Iron measured in mg
ug or mg per day
Ultra-Trace Elements - UTE
- Iodine, Selenium, Manganese, Molybdenum, chromium - measured in ug
Macrominerals (major minerals) -
Bulk Elements - 100mg > like calcium, phosphorus, magnesium, chloride, sodium, sulfur, magnesium
Inorganic
- disturbed in nature
Promote growth and maintaining health
Represent 4% of body weight
Magnesium
Wholegrain breads
Cereals
Veggies
Iron
Wholegrain breads
Cereals
Veggies
Animal protein / beans
Do not take with calcium as inhibits absorption.
Chromium

Cereals
Prevents hypertension, colon cancer and bone loss
Manganese
Wholegrain breads

Potassium
Bran
Bananas/Oranges
Veggies
Dairy
Beans
Helps maintain osmotic pressure
Calcium

Calcium best absorbed at <500mg
Calcium carbonate best with food
Calcium citrate best on empty stomach
Salt and sodium figures are different - 1g sodium = 2.5g salt
High sodium levels linked to high BP - can lead to stroke or heart attack.
Iodine
- Thyroxine - deficiency - goiter / cretinism
Minerals help regulate body processes
Sodium, potassium and calcium are important in the functions of nerve cell transmission and muscle contraction.
Sodium
- maintains fluid balance
Potassium and phosphorus - role in fluid and acid-base balance
Minerals maintain normal haemoglobin levels and nervous system. Involved in hormone activity and skeletal development and maintenance.
Absorbed in the small intestine. Depends on tissue health, food form (animal/plant based) and body requirements.
Sodium is not regulated which can lead to sodium overload
Metabolised independently from one another according to the bodys needs. Each process differs
