Nutrition chapter 8 major minerals

2 main calcium functions

Bone structure and serves as a bank that can release calcium to the body fluids.

Magnesium toxicity

From no food sources only. Diarrhea, ph imbalance, dehydration.

Calcium deficiency symptoms

Stunted growth and weak bones. Bone loss (osteoporosis)

DRI calcium

1k mg/day (19-50 yrs) 1.2k mg/day (51-70 yrs)

Phosphorus is the

2nd most abundant mineral in the body, next to calcium.

Phosphorus DRI intake

700mg / day

To protect against bone loss

Attention to calcium intakes during early life is crucial. A diet too low in calcium may prevent a person form achieving peak bone mass.

Chief functions of magnesium

Bone mineralization, protein synthesis, enzyme action, muscle contraction,nerve function, tooth maintenance, and immune function.

Phosphorus toxicity

Calcification of soft tissues, particularly the kidneys.

Calcium activates

Cellular enzymes that regulate many processes.

Calcium toxicity

Elevated blood calcium, constipation, interference with absorption of other minerals, increased risk of kidney stone formation.

Calcium allows secretion of

Hormones, digestive enzymes, and neurotransmitters.

Nearly all (99%) of the body's calcium is stored

In the bones and teeth.

Magnesium DRI intakes

Men = 400mg. Women = 310mg

Chief functions of phosphorus

Mineralization of bones and teeth, part of phospholipids, important in genetic material, energy metabolism and buffering systems.

Calcium is essential for

Muscle contraction and therefore the heartbeat.

Phosphorus deficiency symptoms

Muscular weakness, bone pain.

Calcium helps maintain

Normal blood pressure, and plays an essential role in the clotting of blood.

3 responding organs to calcium

The intestines (increas absorption of calcium form the intestine) the bones (release more calcium into the blood) the kidneys (prevent its loss in the urine)

Calcium is by far

The most abundant mineral in the body.

Calcium in body fluids regulates the

The sport of ions across cell me,Barnes and is particularly important in nerve transmission.

Magnesium deficiency

Weakness, confusion, if extreme - convulsions, uncontrollable muscle contractions, hallucinations, and a difficulty swallowing. Growth failure.
