Calcium Flashcards
What are sources of calcium
Milk Cheese Sardines Yoghurt Green leafy veg
What are the functions of calcium
Formation of strong bones and teeth
Assists blood clotting
Aids normal muscle contraption
What is the RDA of calcium
Children 800 mg
Adolescents 1200mg
Adults 800 mg
Pregnant or lactating 1200mg
What are the deficiency effects
Bones diseases e.g. Rickets osteomalacia and tooth decay
Slow blood clotting which may cause haymorrhaging
Muscles failing to relax after contraption
What % of calcium is absorbed by the body
20-30%
What vitamin helps with the absorption of calcium
And how
D
Stimulates the amount of calcium binding protein
What hormone assists calcium absorption
Parathormone
Controls levels of calcium in the blood
What mineral binds with calcium
Phosphorus creating calcium phosphate
What factors hinder calcium absorption
Tanning in coffee and tea bind to calcium
Excess dietary fibre binds to calcium
Why does fat hinder calcium absorption
Excess binds to protein making it insoluble
Why does protein effect calcium absorption
As the body burns excess protein it produces sulfate. This increases the amount of calcium in urine
What acid and where is it found can bind to calcium
Phytic acid in bread and seeds
What aids calcium absorption
Vitamin D
Parathormone
Acidic environment
Phosphorus
What factors hinder calcium absorption
Excess fat - insoluble
Excess protein - urine
Phytic acid
Tanning
