Calcium: Strong Bones, Healthy Teeth
Calcium (Ca)
Calcium is widely distributed in nature, and there is a lot of it in the human body. We constantly need to intake this element. Even the Assyrians used crushed swallow beaks, rich in calcium, for physical strength, hand hardness, endurance, and as a remedy for hangovers.
The daily requirement for calcium for an adult is 800–1500 mg per day. In children, calcium is renewed every 1–2 years, while in adults it is renewed every 10–12 years.
The bioavailability of calcium from food is 25–40%.
The kidneys filter approximately 8.6 g/day, almost all of which is reabsorbed, and only 100 to 200 mg is excreted in urine.
The absorption of calcium in the intestine, reabsorption by the kidneys, and renewal in bones are directly regulated by parathyroid hormone, calcitonin, and vitamin D.
Calcium is involved in metabolism, hematopoiesis, increases the body’s resistance to infections and toxins.
Calcium is necessary for the functioning of cell membranes, the operation of the cell’s nuclear apparatus, helps stabilize mast cells, and inhibits the release of histamine, thereby reducing the manifestations of allergic reactions, pain syndrome, and inflammatory processes. It is a factor in blood coagulation, lowers blood cholesterol, and participates in the formation of the immune response.
It is important to emphasize the special role of calcium as a factor in intracellular signaling.
Insufficient intake of calcium in the body increases the excretion of calcium from bones into the blood, causing demineralization of bones and osteoporosis. The need for it significantly increases in pregnant women and nursing mothers.
It has been experimentally proven that proponents of raw food do not know such a disease of bone tissue as osteoporosis, nor do they suffer from arthrosis or radiculitis, as they do not subject vegetables and fruits to heat treatment. During thermal processing, organic calcium converts to inorganic and is not absorbed by the body.
However, calcium in milk is absorbed while we drink it raw, especially fresh. Pasteurized processed milk, as well as yogurt and other dairy products, like baby formulas, contain calcium already in an inorganic poorly absorbable form.
The excretion of calcium from the body is enhanced when consuming an excessive amount of acidic substances, during acidosis.
Calcium is a physiological antagonist of magnesium and is in competitive relations with phosphorus in regulating the formation of the mineral matrix of bone.
Calcium prevents the accumulation of lead in bone tissue.
Calcium, primarily found in bone tissue, is similar in properties to strontium and barium, thus their ions can replace it in bones.
Together with vitamins A, C, D3, F, the level of calcium in the body can be increased by the following elements: iron, magnesium, manganese, phosphorus, silicon, iodine, as well as protein, gastric juice (HCl), pancreatic enzymes, and Lactobacillus acidophilus.
Lead, cadmium, aluminum, magnesium, unsaturated fatty acids, excessive consumption of sugar, protein, thyroid dysfunction, and vitamin D deficiency lead to a decrease in calcium levels in the body.
In an iodine-rich environment (calcium synergists), for example, in the oceans, animals and plants living there have record mass and long lifespan (sea turtles live for 2–3 centuries). It has been noted that livestock in coastal areas differs in size and developed skeleton. Thus, iodine and calcium can work wonders in the lives of biological subjects when acting together.
However, thermal processing of fish destroys the vitamin D3 and iodine present in it, and to preserve valuable substances, it is better to eat fish that is dried, smoked, or salted, as the peoples of the North do.
It is used for the prevention of osteoporosis, regulation of CNS function, in cases of insufficient parathyroid gland function, allergic diseases (serum sickness, urticaria, angioedema, hay fever), to reduce vascular permeability (hemorrhagic vasculitis, radiation sickness phenomena, inflammatory and exudative processes), in skin diseases (eczema, psoriasis), in chronic hepatitis, toxic liver damage, as a hemostatic agent in bleeding, as an antidote in poisoning with oxalic and hydrofluoric acid salts.
Indications for the necessity of calcium application include malnutrition, moist skin, frequent colds, poor tolerance to cold, dairy products, eggs, and weak stools.
There is also a lot of calcium in mushrooms, but during boiling or frying, organic calcium converts to a form that is not absorbed by the body. Only in salted mushrooms, after cold salting due to long soaking before salting, organic calcium is preserved and is absorbable. It is no coincidence that the inhabitants of the shores of Lake Onega and the surrounding Kargopol region were known for their excellent health – they consumed fresh saffron milk caps, lightly sprinkled with salt, rich in organic calcium. The development of their skeleton and muscle mass was passed down in their genes, and therefore during the reign of Elizabeth Petrovna, strong, well-built boys from Kargopol were recruited for the guard.
The best source of calcium is eggshells (the color of the shell does not matter), and quail eggshells contain significantly more calcium compared to chicken eggshells. It consists of 90% calcium carbonate and, unlike chalk, is absorbed almost 100% because the process of forming organic calcium from inorganic has already occurred in the bird’s body. The shell is also rich in other mineral elements: copper, fluorine, iron, manganese, molybdenum, phosphorus, sulfur, silicon, selenium, zinc, etc. – a total of 27 elements.
