Lists of sources, functions, deficiencies and toxicities are not complete

Iron

Functions-oxygen transport (muscle and blood), part of enzyme function Sources-red meats, beef liver, fortified cereals and bread Deficiencies-lower immunity, weakness Toxicities-greater risk of infection, organ damage

Zinc

Functions-tissue growth and wound healing, part of many enzyme functions, vitamin A transport Sources-meat, poultry, fish, eggs, whole grains, milk Deficiencies-abnormal glucose tolerance, impaired wound healing, night blindness Toxicities-anemia, elevated LDL-c and lowered HDL-c, impaired calcium absorption  

Iodine

Functions-part of hormones that regulate growth, development and metabolic rate

Sources- iodised salt, seafood, bread Deficiencies-weight gain, lethargy Toxicities-enlarged thyroid gland

Selenium

Functions-works as an antioxidant with vitamin E Sources-grains grown on selenium rich soil, seafood, liver, kidney Deficiencies-atherosclerosis Toxicities-nausea, vomiting, nerve damage

Copper

Functions-production of haemoglobin, component of several enzymes, energy metabolism Sources-organ meats, seafood, nuts, seeds Deficiencies-rare- anemia Toxicities-vomiting, diarrhea 

Manganese

Functions-component of enzymes involved in fat synthesis, growth, reproduction and blood clotting Sources-widely distributed in foods, best sources are whole grains, tea, pineapple, and strawberries Deficiencies-rare Toxicities-rare-nervous system disorders

Fluoride

Functions-formation of tooth enamel, prevention of dental decay, bone formation Sources-fluoridated water and tea Deficiencies-dental decay, increased risk of osteoporosis Toxicities-mottling of teeth, nausea, vomiting 

Chromium

Functions-assists in insulin function Sources-meat, whole grains, nuts, cheese Deficiencies-insulin resistance, impaired glucose tolerance Toxicities-dietary toxicity unknown, occupationally chromium dust damages liver and kidneys

Molybdenum

Functions-component of many enzymes, works with riboflavin to incorporate iron into hemoglobin Sources-milk, legumes, bread, milk, grains Deficiencies-unknown Toxicities-occupational exposures causes gout-elevated uric acid in blood-cause arthritis
