Calcium and phosphorous are the two main minerals needed to build and maintain healthy teeth and bones. They are present in the body in the forms of tricalcic phosphate and calcium carbonate.

– Mineral phosphate is obtained from potassium phosphate, while organic phosphate is found in milk, eggs and vegetal phytines.

– Calcium is obtained from mineral salts and, in its complex form, combined with proteins in carrots, turnips, dried legumes, dried fruit, egg yolk, dairy products, etc.

Other minerals are indispensable for life. They include:

– iron, which is a main constituent of haemoglobin;

– potassium, necessary for nervous system functions as well as for the metabolism of sugars and protein;

– magnesium, whose metabolism is closely linked to that of phosphorous and calcium;

– iodine, indispensable for producing thyroid hormones;

– sulphur, which helps metabolize proteins;

– fluoride, to maintain healthy bones and teeth.

Calcium metabolism

In order to absorb calcium properly you need:

– a healthy and intact intestinal lining, which means a general absence of digestive problems;

– sufficient ionization of calcium;

– a sufficient amount of Vitamin D.

Daily calcium requirements for an average adult are about 800 milligrams. Double that amount for growing children, and triple it for pregnant or lactating women.

Phosphorous metabolism

Phosphorous is lost in the kidneys and intestines. Losses vary, depending on the type of diet you’re on, but cease altogether during periods of fasting.

An average adult needs about 800 milligrams of phosphorous per day (double the amount for growing children, and triple it for pregnant or lactating women.)

Persons who eat normally rarely develop a phosphorous deficiency.

Phosphorous metabolism is directly linked to the body’s pH (acid – alkaline) balance. When your pH balance is disturbed, a loss of minerals occurs. This happens very rarely to persons who:

– eat a balanced diet;

– get enough exercise and exposure to sunlight;

– do not take potentially toxic medications;

– do not drink too much coffee or alcohol;

– do not ingest too many acidic foods (tomatoes, rhubarb, gooseberries, etc.);

– do not overeat or drink too much in general.

The long-term effects of an overly acidic diet can be very harmful:

– bones: osteoporosis, osteomalacia, rickets;

– teeth: insufficient calcification, defective growth of teeth and the bony part of gums, premature abrasion, improper enamel maturation, fragile teeth (especially among pregnant women), and increased incidence of tooth decay and broken teeth;

– adolescents: retarded closing of the apex (the tip and contiguous portion of the blade of the tongue), increased incidence of tooth decay, extreme sensitivity to cold, bone and muscular weakness, lowered resistance to infection.
