Minerals Flashcards
What are macrominerals?
‘major’ minerals required by the body in amounts of 100mg or more per day
maintenance of fluid and electrolyte balance within the body,nerve impulse conduction,muscle contractions and providing cells and tissues with structure.
What are microminerals
required by the body in trace amounts (very small amounts) per day(<0.01%)
Acting at a cellular level they regulate many functions in the body including the uptake of other minerals in the diet and are usually found as part of any enzyme.
3 examples of macrominerals
Phosphorus (P)
Potassium (K)
Sodium (Na)
3 examples of microminerals?
Iodine (I)
Zinc (Zn)
Iron (Fe)
Potassium - What the mineral does in the body?
Potassium is needed to maintain fluid balance in the body (acids and bases).
It’s really important for normal, regular heart, muscle and nerve functions as well as enzyme function
Potassium - Deficiencies – what can this cause? (3)
How does it occur? (3)
Cardiac arrest
Weakness,
Loss of appetite,
Nervous disorders
Poor growth
Potassium deficiency occurs due to - chronic vomiting, kidney disease, burns and other illnesses.
Potassium - Excess - what can this cause?
Potassium toxicity.
Occurs due to Addison’s disease where the adrenal gland doesn’t produce enough of the hormone that regulates potassium. Symptoms include arrhythmia, weakness and collapse.
Potassium - food sources
Apple cider vinegar, seaweed, banana, green leafy vegetables, parsley
Calcium - What the mineral does in the body?
Mineral needed alongside vitamin D to develop and maintain healthy bones and teeth.
Plays a vital role in many systems including metabolic processes, transporting information via the nervous system, control of muscle contraction – including heart rhythm and blood clotting
Calcium - Deficiencies – what can this cause?
Hypocalcaemia
Heart irregularities, young animals - poor bone growth and dental development.
Identified in low bone density because bone acts as a reservoir in times of need
Insufficient calcium in bones can result from an inadequate supply of vitamin D which is essential for the absorption of calcium
Calcium - Excess - what can this cause?
Excess (Hypercalcemia): Increased urination & thirst, Kidney disease - lack of appetite (anorexia), Vomiting and Decreased gastrointestinal function, urolith formation
Calcium - food sources
Green leafy vegetables, fish, egg/shell, dairy products, wholegrains
Phosphorus - What the mineral does in the body?
Aids skeletal rigidy with calcium, Filters waste from kidney; Energy utilisation and transfer, Maintains osmotic pressure
Phosphorus - Deficiencies – what can this cause?
Hypophosphatemia.
Slow rate of growth in young animals, Lethargy, Loss of weight, Muscle weakness
Phosphorus- Excess - what can this cause?
Hyperphosphatemia - disruption in electrolytes.
urolithiasis
Muscular spasms
Tremors
Phosphorus food sources
Oats, bran, black sunflower seeds, raw meat, fish, eggs, dairy, dried fruit
Sodium - What the mineral does in the body? 4
Main component of extracellular fluid
Maintains fluid balance in the body /regulation of pH.
Nervous impulses and maintaining electrolyte balance in the body.
Muscle function - ie heart contraction
Sodium - Deficiencies – what can this cause? (4)
What is it called ? (1)
Low sodium is called hyponatremia
Lethargy
Weakness
Nausea/vomiting
Dullness
Dehydration
Confusion
Seizures
Sodium- Excess - what can this cause? (4)
What is this called?
Hypernatremia and can be caused by dehydration or overheating
Increased thirst and water consumption
Excessive thirst and urination
Weakness and lethargy
Confused, disorientated
Muscle twiches and trembling
Hypertension (high blood pressure)
Sodium - food sources
Kelp, celery, rock salt, seaweeds, watermelon, ocean fish, asparagus
Magnesium - What the mineral does in the body? 3
Required for muscle contraction and neuromuscular function
Constituent of organelles such as the mitochondrion
Cofactor in enzymes involved in energy transport
Magnesium Deficiencies – what can this cause? (4)
anorexia, numbness, tingling, muscle cramps, seizures, muscle spasticity, personality changes, abnormal heart rhythms.
Magnesium - Excess - what can this cause?
digestive issues, lethargy and an irregular heartbeat.
Urolith formation. In rare cases can be fatal.
Magnesium - food sources (4)
Green leafy vegetables, nuts, seeds and whole grains seaweed, bran, dandelion, soybeans
