Minerals Are Essential to our Health ?
Lives are just born from a pregnant woman naturally. It looks straight forward. Our scientists studied and found components of our body. i.e. carbon, oxygen, nitrogen etc. Except carbon, hydrogen, oxygen, nitrogen, the rest of elements are called minerals.
What is mineral?
Our body contains nearly all minerals on earth. Among minerals, there are 20 elements that constitute of human tissues, involve cell metabolism and maintain body function as need.
Minerals can be classified into two categories, Macro and Micro element.
Macro elements – The quantity of elements in the body is higher than 0.01%.
There are Sodium, Potassium, Calcium, Magnesium, Chloride, Sulfur.
Micro elements – The quantity of elements in the body is less than 0.01%.
There are Iron, Copper, Iodine, Zinc, Selenium, Manganese, Silicon, Molybdenum, Nickel.
The characteristic of the minerals in our body
- They cannot be formed inside our body naturally. They need in cell metabolism.
- Each element has its uniqueness. It exists in different area inside of our body.
- Minerals have to be involved all together participating in cell metabolism. They all maintain balance state. Too much on one element can repel other element.
- Some minerals may generate poisoning.
The physical functions of minerals in our body
- Minerals form our body. I.e. bone, teeth, nerve, muscle, blood, glands.
- Maintain cell osmotic pressure and cell membrane permeability. Excessive or lacking effects of body fluid balance. Dehydration or edema occurs.
- Maintain body fluid pH balance.
- Maintain neuromuscular normal, i.e. potassium, calcium, sodium, magnesium.
- Constitute a special physiological function of vitamin, protein, hormones, i.e. iron, iodine, selenium, silicon.
- Constitutes the activator and constituent components of the enzyme system, i.e. calcium, magnesium, zinc, selenium.
Reasons of Minerals Deficiency
- The distribution of elements in our environment is out of balance.
- Some foods contains anti-mineral component, i.e. oxalic acid, phytic acid
- Improper way of cooking, i.e. sinking, boiling in the water.
- Improper habit of eating, foods contains less minerals.
Calcium Facts and functions in the body
- 2% of body weight
- 99% in bones, teeth
- 1% in body fluids
- Keeps heart and nerves working properly.
- Blood clotting
- Hormones secretion
- Maintain body flood PH balance
- Involved in the regulation of the activity of metabolic enzymes in vivo.
- Maintain cell membrane integrity and permeability, affecting cell phagocytosis, division, secretion
Calcium Absorption and metabolism – Calcium absorption decrease with age; Calcium absorption depends on the body Vitamin D content
- Infant absorption = 50%
- Children absorption = 40%
- Adult absorption = 20%
- Senior absorption = 15%
Factors that affect Calcium absorption
- High intakes of sodium, caffeine or protein cause an increase in the urinary excretion of calcium.
- High consumption of potassium reduces the urinary excretion of calcium.
- Vitamin D accelerates the absorption of calcium from the gastrointestinal tract.
- Certain types of dietary fiber like the fiber found in wheat and oat bran, may interfere with calcium absorption by decreasing transit time, limiting the amount of time during digestion for calcium to be absorbed.
- Dietary fiber also stimulates the proliferation of friendly bacteria in the gut, which bind calcium and make it less available for absorption.
- Phytic acid, found in whole grains, nuts and legumes can bind to calcium to form and insoluble complex, decreasing the absorption of calcium.
- Oxalic acid, found in spinach, beets, celery, pecans, peanuts, tea and cocoa, can bind to calcium and form an insoluble complex that is excreted in the feces.
- High fat diet-fatty acids form calcium soaps that cannot be absorbed.
- Excess phosphates, magnesium and iron decrease absorption.
- Advancing age and intestinal inflammatory disorders inhibit absorption of calcium.
