Know about Vitamins and Minerals ..3
Posted in 2012

The body needs, and stores, fairly large amounts of the major minerals. These minerals are no more important to your health than the trace minerals; they’re just present in your body in greater amounts.
Major minerals travel through the body in various ways. Potassium, for example, is quickly absorbed into the bloodstream, where it circulates freely and is excreted by the kidneys, much like a water-soluble vitamin. Calcium is more like a fat-soluble vitamin because it requires a carrier for absorption and transport.

Major minerals

  • Calcium
  • Chloride
  • Magnesium
  • Phosphorus
  • Potassium
  • Sodium
  • Sulfur

What they do

One of the key tasks of major minerals is to maintain the proper balance of water in the body. Sodium, chloride, and potassium take the lead in doing this. Three other major minerals—calcium, phosphorus, and magnesium—are important for healthy bones. Sulfur helps stabilize protein structures, including some of those that make up hair, skin, and nails.

Words to the wise

Having too much of one major mineral can result in a deficiency of another. These sorts of imbalances are usually caused by overloads from supplements, not food sources. Here are two examples:
  • Salt overload. Calcium binds with excess sodium in the body and is excreted when the body senses that sodium levels must be lowered. That means that if you ingest too much sodium through table salt or processed foods, you could end up losing needed calcium as your body rids itself of the surplus sodium.
  • Excess phosphorus. Likewise, too much phosphorus can hamper your ability to absorb magnesium.

A closer look at trace minerals

A thimble could easily contain the distillation of all the trace minerals normally found in your body. Yet their contributions are just as essential as those of major minerals such as calcium and phosphorus, which each account for more than a pound of your body weight.

Trace minerals

  • Chromium
  • Copper
  • Fluoride
  • Iodine
  • Iron
  • Manganese
  • Molybdenum
  • Selenium
  • Zinc

What they do

Trace minerals carry out a diverse set of tasks. Here are a few examples:
  • Iron is best known for ferrying oxygen throughout the body.
  • Fluoride strengthens bones and wards off tooth decay.
  • Zinc helps blood clot, is essential for taste and smell, and bolsters the immune response.
  • Copper helps form several enzymes, one of which assists with iron metabolism and the creation of hemoglobin, which carries oxygen in the blood.
The other trace minerals perform equally vital jobs, such as helping to block damage to body cells and forming parts of key enzymes or enhancing their activity.



My advise
1...  Vitamins and minerals are most important for us to keep healthy
2...  Vitamins and minerals are often called micronutrients because your body needs only tiny amounts of them. Yet failing to get even those small quantities virtually guarantees disease.
3...  Old-time sailors learned that living for months without fresh fruits or vegetables—the main sources of vitamin C—causes the bleeding gums and listlessness of scurvy
4...   In some developing countries, people still become blind from vitamin A deficiency.
5...   A deficiency in vitamin D can cause rickets, a condition marked by soft, weak bones that can lead to skeletal deformities such as bowed legs. Partly to combat rickets, the U.S. has fortified milk with vitamin D since the 1930s.
6...    A combination of calcium, vitamin D, vitamin K, magnesium, and phosphorus protects your bones against fractures.
7...   Taking folic acid supplements early in pregnancy helps prevent brain and spinal birth defects in offspring.
8...   The mineral fluoride not only helps bone formation but also keeps dental cavities from starting or worsening.
9...   All vitamins and minerals are available in your healthy food. Eat and protect your health.
