Calcium, Health, definition and supplements
Calcium is one of the best-known of all the minerals, next to iron. Part of this is due you to the milk counsel and their unceasing advertisements for the consumption of milk and milk products. Milk is a superb form of calcium and other essential minerals as well as vitamins, both free and in essential fatty acids. It is easily absorbed in the gut, and is very inexpensive to stock in the household.
Calcium is still predominantly in the bones, and act dynamically in their use and disposal of calcium. This is a regulated by the hormones, which keeps a calcium store continually in the bloodstream, and excesses are deposited in the bones for their use, and for the body’s use at a later time.
Not having enough calcium, is normally the fault of an inadequate dietary supply, or if calcium is physically lost. Absorption of calcium is rarely a problem, although calcium is dependent upon a few other vitamins and minerals for their correct assimilation. And so it follows that if you have a vitamin and mineral deficiency in other areas, this will greatly affect the percentage of calcium that you can resource from foods to a reduced level.
Children, adolescents, and nursing mothers as well as pregnant females require high levels of calcium. The last two are losing, all have lost, calcium to the growing infants during development, and so needs to replenish their calcium supply as soon as possible, to prevent bone problems much later in life. The young obviously, need calcium to keep growing, and as all bones do not grow at the same rates, an abundant supply is absolutely necessary to prevent minor malformations. This is not usually serious, but the loss of the abundance of calcium, can cause stunted growths , give formations of the spine, and legs. It has also been blamed for weak bones that cause the young to break bones in minor trips or falls.
When humans grow, the bones increasing size and this requires calcium levels to be high at that point, when growth stops in the late teens and early 20s, bone mass, the amounts of bone and calcium, continues to increase up until the early 30s. This points is termed peak bone mass, and after this time the bone mass begins to decline and no longer increases in size. This point can be extended with a good diet and regular exercise. This decline in bone mass is directly related to the calcium intake and strength of bones that were created in the first 30 years of life, and so those who have had better diet, and have had enough exercise, we lose bone mass at a much lower rate. It is easy to see why it is important for the young to take in enough calcium and other necessary associated vitamins and minerals, and take enough exercise so as by age 30, to have reached bone mass maximisation for health in later years.
The absorption of calcium also requires vitamin D., zinc, copper and manganese. Keeping good levels of these would assist the body in keeping the bone structure at its best level, as well as helping the young reach their maximum potential peak bone mass.
Losing calcium.
Drinking excessive amounts of alcohol, and nicotine has damaging effects on the body’s ability to obtain, and utilize calcium. Mothers who breast-feed must pay particular attention to that calcium, and related vitamin and mineral intake, as mothers milk is excessively high in calcium, although the mother’s physiology does not allow to increase the absorption percentage from the food that she eats. Adolescents gals also need a high level of calcium as they need more calcium at that time than at any previous points in their lives.
How much calcium is enough calcium.
In the United States the RDA, recommended daily allowance, is about 1200 mg for those between 11 and 25 years old. Although, this is not a hard and fast rule, as adolescents gals will require a peak of calcium intake at 14 to 19, and those that are small at age 11 will not require the maximum amount. This figure has been greatly increased, in order to combat the growing problem of loss of bone density. The ages of 11 to 25 is considered to be the age at which a body can produce maximum bone density forgiving earlier lapses.
Osteoporosis
As we have read, calcium is essential for bone health a poor intake of calcium, and the associated vitamins and mineralssupplements, would allow the bones to become weak, and brittle, and can break easily, and even fracture. This is a much larger problem for women than it is for men. Estrogen, is a hormone that is especially important for the correct metabolism of calcium, most especially so for women. Estrogen comes from the ovaries in a woman, and usually problems begin after the menopause, when estrogen production drops very sharply. This means that calcium is not properly used within the bones, or stored efficiently, and loss and replacements becomes more haphazard. As the body uses the bones as a storage vessel for calcium, it continues to draw calcium from them, but unfortunately draws much fast the then it’s replenishes. Over time the bones become weaker. Osteoporosis is the term given to this problem, and is best described to be a honeycomb in effect, when saying under a microscope, of the bone. Osteoporosis onsets much quicker in those women that have had poor bone densities during the important is that lead up to peak bone mass, as well as smoking cigarettes, drinking alcohol to excess, or generally eats low calcium, or otherwise poor diets. In recent years hormone replacement therapy (HRT) has managed to slow this effect, coupled with eating calcium rich foods, such as milk, yogurt’s, dark green leafed vegetables.
It is also recommended that’s calcium supplements be taken, preferably those that have zinc, copper and manganese already added, in the region off 1500 mg per day.
