When it comes to vitamins and minerals, is the Recommended Daily Allowance (RDA) sufficient

Many people are under the impression that, if their intake of nutrients meets the RDA, then they are getting enough to stay healthy.

However, as Linus Pauling, Nobel Prize winner, once said;

"RDA for a vitamin is not the allowance that leads to the best of health for most people. It is instead, only the estimated amount that for most people would prevent death or serious illness from overt vitamin deficiency.

Values of the daily intake of the various vitamins that leads to the best of health for most people may be several times as great as the values of the RDA".

Meeting the RDA for nutrients is the bare minimum for maintaining optimal health throughout our life. Optimal nutrition requires much more than the RDA and this does not decline as we grow older. In fact, the need for optimal nutrition increases and it certainly does not decrease as one would get the impression if one were to examine the typical diet fed to our elderly in institutional care. As we grow older our caloric expenditure declines, so we eat less. At the same time illness, decline in digestive efficiency and medications combine to cause states of chronic malnutrition that is widespread in elderly populations.

When levels of a nutrient are low in the body, merely achieving the RDA will, at best, stem further drops in body levels. A good example is low iron levels which affect up to 50% of some populations like young women and the elderly. If a person is told their iron levels are low then it is necessary to consume several times the RDA to bring about an appreciable improvement in body stores. It can take several months, if not a year or two, of steady supplementation to build stores of iron in the organs to optimum levels. Of course, regular blood test or, better still, a Hair Tissue Analysis will guide the supplementation.

It is more difficult than ever to get the essential vitamins and minerals from our food, despite improvements in "quality" and freshness. This paradox is due to the selection of plants for their nice taste and speed of growth, rather than nutrient density. The same can be said of animal sourced foods such as the succulently soft battery chicken. Furthermore, the nutrient density of our agricultural soils continues to steadily decline as only those that are necessary for plant growth are replaced.

Like it or not, the case for supplementing one's already good diet with various vitamins and minerals grows stronger by the day. If you are not sure of your nutritional needs, then investing in a Hair Tissue Mineral Analysis or an Active Elements Assessment helps you to take out the guesswork.

How Medication Causes Anaemia in Senior Citizens

Anaemia should be considered a critical health concern for everyone over the age of 50. This is especially so for those who are taking prescription drugs, because many have a side effect that you'll never see mentioned on the label: the impairment of essential vitamin and nutrient absorption.

Red blood cells deliver oxygen from the lungs to the tissues throughout the body. Anemia occurs when the red blood cell count becomes depleted, resulting in fatigue, weakness, and hair loss in extreme cases. The two primary causes of anaemia are iron-poor blood (often triggered by menstruation or internal bleeding), and a deficiency in two critical vitamins: folic acid and vitamin B-12. Getting good amounts of these nutrients is very important for seniors because as we age our ability to absorb vitamins from food diminishes. Consequently, our tendency to develop anaemia rises.

Unfortunately this absorption problem is just the first link in a chain of events that adds up to a health issue that's far more serious than simple fatigue.

Many prescription pharmaceuticals interfere with the absorption of nutrients. For instance, drugs that inhibit stomach acids have been shown to significantly decrease absorption of vitamin B-12; one of the primary vitamins needed to prevent anaemia.

Other medications that are known to play a role in nutrient depletion are among the most frequently prescribed medications on the market. Antibiotics, anti-depressants, anti-inflammatories, blood pressure medications, cholesterol- lowering drugs, estrogen, and tranquilizers can all strip valuable vitamins and minerals from the body. When any of these drugs are combined - especially in an older patient - the risk of developing anemia rises.

And now it seems that this chain of events is being rushed along more quickly than ever. Did you know the average American senior receives 25 prescriptions annually - a 100 percent jump in just four years! So as the over-medication of seniors grows at an alarming rate, we see two serious problems becoming even greater health threats:

• The wider variety of drug intake creates conflicting side effects (and as know, many doctors treat drug side effects with other types of drugs), and
• These potent drug mixes rob patients of the very nutrients they need most when fighting an illness.

But the chain of events just keeps getting worse. Many mainstream doctors see so many elderly patients who have anaemia that the condition is widely regarded - somewhat lightly - as a normal part of ageing. As a result, when anaemia is diagnosed it often goes untreated. This is a mistake because anaemia dramatically increases the risk of mortality for those with chronic health problems such as heart disease. At the same time, anaemia can also promote cancer, which thrives in a cellular environment that's starved of oxygen.

Anaemia is easily diagnosed with a blood test, so during your next check up, ask your doctor for a test of your red cell blood count - especially if you're feeling unusually fatigued. If you do have an anaemic condition, the next step is to find out the cause. If your doctor downplays anaemia's importance, or if a prescription drug is recommended to address the problem, you should get a second opinion.

As for treating anaemia, you simply can't go wrong with the right nutrition and supplements. High doses of B group vitamins can be helpful, but not necessarily iron supplements. Take a broad spectrum Natural vitamin B supplement twice daily with iron rich food. The best source of iron is from natural dietary sources, plus a supplement from natural sources that steadily restore levels to normal.

The best dietary sources of iron red meat, fish, pork, and poultry, with beef liver and chicken liver having the highest amounts of iron. An additional intake of high quality vitamin C with iron rich food can also help the body absorb iron. Even an orange juice with your meal will help.

Talk to your doctor about discontinuing the use of any drugs that aren't absolutely necessary.
