Bone-Building Nutrients

Posted by dodo on Nov-3-2008

The ability to keep your bones strong (a prerequisite for preventing arthritis and osteoporosis) depends to a large extent on how your body makes use of calcium, magnesium and phosphorus. Of these, calcium is the most abundant mineral in bone. However, more and more evidence is accumulating to show that dietary calcium intake is only one of a number of factors that influence the proper use of calcium in the body. The degeneration of cartilage seems to herald the beginning of osteoarthritis, the most common form of arthritis. And the cartilage of osteoarthritic sufferers appears to be different in composition from that of non-sufferers. Read the rest of this entry »

Calcium and Magnesium

Calcium is the most abundant mineral in the body, accounting for 1.6 per cent of our body mass. Of the 1200g of calcium in us, more than 99 per cent is in our bones and teeth. The rest is present in muscles, nerves and the bloodstream, where it plays a crucial role in many enzymes and the production of nerve signals and muscular energy.

Calcium is relatively well absorbed, with an average of 30 per cent of ingested calcium reaching the bloodstream. But its absorption into the bloodstream depends on many factors. An excess of alcohol, a lack of hydrochloric acid in the stomach, or an excess of acid-forming foods (mainly protein) decrease its absorption. So does the presence of lead, which competes with it for absorption sites. Read the rest of this entry »

The safety of minerals depends on three factors. Firstly, the amount — all minerals show toxicity at exceedingly high doses. Secondly, the form — trivalent chromium, for example, is essential, while hexavalent chromium (which is not found in food or supplements) is very toxic. Thirdly, the balance with other minerals in the dietiron supplementation, for instance, can exacerbate zinc deficiency since it is a zinc antagonist. The reason for this antagonism is that many minerals are atomically very similar to each other. So if you lack one mineral but take in an excess of another similar mineral it can slot into the wrong enzyme, speeding up or slowing down or simply stopping the enzyme from working.

Vitamins and Longevity (Vitamin C & D)

Vitamin C (Ascorbic Acid)

Vitamin C is the great healing vitamin of the body. It has many functions and is very important, especially when the body is under some stress, such as during a prolonged illness or when fighting a severe infection. It is needed for the cells that produce the collagen substances that hold the tissues together. It is particularly important in maintaining the walls of the smaller blood vessels. It also aids in the absorption of iron from the digestive tract. Read the rest of this entry »

Phosphorus

Another very important mineral upon which the body depends is phosphorus. This mineral plays a leading part in many of our vital processes.

It is present in every tissue and has much to do with the growth and functions of all the cells of the body. Phosphorus enters into a great many different chemical reactions, especially those involving enzymes, proteins, and carbohydrates.

Phosphorus is essential for all the muscles. Believe it or not, you could not lift an eyebrow without phosphorus! It is part of the nuclear structure of every cell. Phosphorus also helps to maintain the normal acid-base balance of the body.

In combination with calcium it forms a large part of the bony framework on which the rest of the body depends. It is essential in building sound, healthy teeth. Most of the phosphorus in the body is stored in the bones. Like calcium, it can be drawn upon for needs elsewhere. Read the rest of this entry »

Within the human body there is a surprising assortment of minerals. They have much to do with keeping us in good physical condition. Some minerals, such as calcium and phosphorus, are needed for building strong bones and teeth. If it were not for these, our bodies would collapse. Other minerals act more or less like chemical “spark plugs” through their association with the enzyme systems of the body. Still others have special functions of their own to perform.

The chief minerals of the body are calcium, phosphorus, iron, and iodine. We need more of these than of the others. For that reason, these four are the most likely to be missing from a deficient diet. There are only traces of the other minerals in the body, but most of them must also be present for normal health.

How Much Calcium Do You Need?

Not everyone agrees with the formal RDAs for calcium. A National Institutes of Health consensus panel on osteoporosis has advised that women consume more calcium than recommended in the RDAs-1,500 mg in the years after menopause if they are not taking supplemental estrogen. The National Osteoporosis Foundation recommends 1,000 mg per day for postmenopausal women who are not on estrogen replacement therapy.

 

Optimal Daily Allowance

Although the RDAs call for only 800 mg of calcium for men and women over the age of 25 (with an increase to 1,200 mg for pregnant and lactating women), we recommend a daily intake of 1,500 mg for everyone. Women clearly need more calcium to help protect them against osteoporosis, even if they are postmenopausal and on hormonal replacement therapy (which can also help protect their bones).

Calcium, the most abundant mineral in the human body, makes up about 2 percent of your body weight. About 99 percent of that is in the bones and teeth; the rest is in tissues and in the body fluids that bathe the cells. In order for your body to absorb the calcium from your diet and make use of it, you also need sufficient amounts of vitamin D.

A mechanism built into your body keeps the levels of calcium in your blood balanced—at sufficient but not excessive amounts. When calcium levels begin to rise too high, the thyroid manufactures a hormone called calcitonin, which draws excess calcium from the blood and deposits it in the bones; urine and feces also carry extra calcium out of the body. Conversely, when calcium levels dip too low, the parathyroid produces a hormone that pulls stored calcium from the bones and sends it to the blood. If the latter process goes on for too long, the bones are depleted of the calcium they need and become thin and weak. Read the rest of this entry »

Essential Nutrient Zinc and Vitamin Supplement

Posted by dodo on Jun-29-2008

Except for iron, no other trace mineral is as prevalent in the body as zinc. And few have been as highly promoted. You may have heard a lot of claims about zinc, in fact; many myths have flourished around this mineral. Zinc has been touted as a treatment for angina, acne, liver disease, and lack of energy— despite scarce evidence to support any of these claims. Some proponents have even insisted that zinc stimulates sexual potency.

Setting aside the spurious claims, zinc is an essential nutrient that plays important roles in the body. It is present in all of the body’s cells, with large amounts in the eyes, liver, bone, skin, hair, and nails. Read the rest of this entry »

Vitamins: How and When continue…

Time Release and Sustained Release

A major step forward in vitamin manufacturing has been the introduction of time release supplements. Time release also known as sustained release is a process by which vitamins are enrobed in micropellets [tiny time pills] and then combined into a special base for their release in a pattern that assures eight- to twelve-hour absorption. Most vitamins are water soluble and cannot be stored in the body. Without time release, they are quickly absorbed into the bloodstream, and, no matter how large the dose, are excreted in the urine within two or three hours.

Time-release supplements can offer optimum effectiveness, minimal excretary loss, and stable blood levels all during the day and through the night. Read the rest of this entry »
