Question

the goal is for you to use the lecture slides and notes to fill-in the 20 points Minerals table:

Each Mineral (8) will be worth up to 2 pts to complete, except Calcium and Iron which will be worth a little more. Coppers will not be included, even though the slides is attached to the end of the lecture.

- Function: What is the one or two major functions of the mineral? (0.5 pt)

- Sources: What are three plant and three animals sources of the mineral? (0.5 pt)

- Deficiency: What the major (or two) deficiency for the mineral? (0.5 pt)

- Toxicity: What is the major toxicity? (0.5 pt)

Answer 1

Mineral	Function	Sources	Deficiency	Toxicity
Sodium	Maintaining blood volume and blood pressure, cellular osmotic pressure and transmitting nerve impulse	Plant: beets, celery, carrots Animal: Meat, Fish	Hyponatremia characterised by altered personality, lethargy and confusion	Swelling in the extremities and high blood pressure
Potassium	Water balance and acid base balance in blood and tissue, transmission of electrical impulses in the heart	Plant: Winter squash, sweet potato, potato Animal: Met, poultry, fish, milk	Weakness and fatigue, muscle cramps	Tingling of the hands and feet, muscular weakness
Magnesium	Normal nerve and muscle function, supports a healthy immune system	Plant: avocado, nuts, legumes Animal: Red meat, fish, seafood	Tremor, poor coordination, muscle spasm	Hypotension, nausea, vomiting, facial flushing
Calcium	Building strong bones and teeth, clotting of blood	Plant: seeds, beans, almonds Animal: milk, yogurt, cheese	Nervous system highly irritable, spasms of hand and feet	Stomach upset, nausea, vomiting and constipation
Iron	Heme synthesise, Myoglobin synthesis	Plant: nuts and seed, legumes, tomato Animal: lean beef, chicken, fish	Iron deficiency anaemia	It can cause iron poisoning and death in children
Zinc	Defensive function, cell division, cell growth and wound healing	Plant: legumes, seeds, nuts Animal: meat, egg, diary	Growth retardation, loss of appetite, impaired immune function	Stomach pain and diarrhoea
Selenium	Role in metabolism and thyroid function, protect the body from damage caused by oxidative stress	Plant: brazil nut, brown rice, sunflower seed Animal: beef, chicken	Extreme fatigue, mental slowing, goitre	Nausea, vomiting and nail discoloration
Fluoride	Prevent tooth decay	Plant: tea, dried fruit Animal: bones of animal	Tooth decay, osteoporosis	Gastro intestinal discomfort,
