Major Mineral- Phosphorus Flashcards
Explain sources of Phosphorus
-Easily obtained
-Milk/ dairy products
-meat
-fish
-green veg
-legumes- peas and beans
What are the functions of Phosphorus
-The second most abundant mineral in the body after calcium. 85% is combined with CALCIUM- to form CALCIUM PHOSPHATE- gives strength to bones and teeth
-Part of the nucleic acids (DNA and RNA)- form of phosphoric acid- these carry INSTRUCTIONS for NEW CELL FORMATION and necessary for GROWTH (children)
-Many ENZYMES and B VITAMINS need phosphorus to function- key to METABOLISM of macronutrients
What are Phosphorus Requirements?
-same- apart from lactating- need extra- due to demands of BOTH mother and baby
What is a Deficiency in Phosphorus?
-cause bone disorders- RICKETS (children) and OSTEOMALACIA (adults)
-Improper balance of Phosphorus and Calcium- OSTEOPOROSIS
-Reduced Phosphate CONCENTRATION in blood- HYPOPHOSPHATEMIA
What is an excess of Phosphorus?
-Too much carbonated drinks (coke)- cause problems- phosphorus content
-Interfere with IRON absorption- annoy the CALCIUM/ PHOSPHORUS RATION (1:1)- ability to use Calcium is REDUCED
Explain Bioavailability for Phosphorus?
-85% of Phosphorus in the body combines with Calcium- Calcium Phosphate- 1:1
-Phosphate leaches out when cooked in water
