You need to be something of a detective, to be a Nutrition Consultant. Often clients only visit when conventional medicine has failed to solve their health problems. When confronted by such mysteries, it's useful to have some objective investigative tools at my disposal. My favourite is the Hair Mineral Analysis, or HMA. I will suggest this immediately if I suspect that health problems could be arising as a result of toxic metal overload.



Hair contains all the minerals present in the body and, in most cases, reflects the quantity of these elements in your tissues. Analysis of this information provides a wealth of information on how efficiently your body is working and its nutritional status. Blood tests report mineral levels at the time the test is taken, rather than longer term levels. As an example, suppose you had recently eaten a potassium-rich banana. A blood test could report a high level of potassium when in fact you may need a potassium supplement. Hair analysis reflects your body's storage of potassium over a period of time, not what you ate that day, or even that week. Likewise, urine tests measure what is being excreted from your body, which is not necessarily what has been absorbed as fuel.

Trace minerals are essential in countless metabolic functions in all phases of the life process. According to the late author and noted researcher, Dr Henry Schroeder, trace elements (minerals) are "more important factors in human nutrition than vitamins.

Mineral imbalances can arise from improper diet, stress, medications, pollution and even from taking the incorrect type or amount of a nutritional supplement.

How is the test carried out? Taking a hair sample is simple, non-invasive and pain free. Any one can do it. Just a small quantity of hair (about a tablespoonful) is needed. This should be taken from several different sites on the back portion of your head. The hair must be about one to one and a half inches from the root end - it's important to cut off and discard any hair longer than that.

This is dispatched to a lab in the USA that specializes only in hair analysis. On arrival it is prepared for testing and then acids are added to break the hair down, separating out the elements contained in the hair protein. After "digestion" the remaining mineral salts are put into solution and analyzed by sensitive and specialized instruments.

The results are interpreted to produce nutritional mineral levels, their interrelationships and metabolic categorization. The report is then personalized for you, complete with graphs and explanations which may give you answers you have been seeking for years.

Why the USA? After evaluating various services I settled on this lab because it offered excellent value for money. a superb report and a fast service. My own report contained 18 pages of information (others may differ, depending on findings) and was delivered within a fortnight at a cost of £50. 38 mineral levels were shown, and significant ratios between them, plus my metabolic type, a recommended supplement and program, and dietary suggestions designed to improve my balance of minerals. At the other end of the spectrum was a UK service which I won't name. Although it was a few pounds cheaper, I waited 8 weeks for its return then received just one sheet of paper giving levels of 19 minerals. No explanations, no ratios, no interactions, no graphs, no analysis. You get what you pay for.

Are there any problems? You will be asked to specify which hair preparations you used, as some hair treatments can contaminate scalp hair. For instance dyes may contain lead acetate, bleaching processes affect calcium and certain medicated shampoos contain zinc or selenium. However, only that individual element is affected. All the others tested are valid. For balding clients, hair from other bodily parts can be used instead of scalp hair - so long as this is specified on the sample!

Is it reliable? Hair is used as one of the tissues of choice by the Environmental Protection Agency in determining toxic metal exposure. A 1980 report from the E.P.A. stated that human hair can be effectively used for biological monitoring of the highest priority toxic metals. This report confirmed the findings of other studies in the USA and abroad, which concluded that human hair might be a more appropriate tissue than blood or urine for studying community exposure to certain trace elements.

Some health-care professionals are not convinced of the validity of hair analysis. However, peer-reviewed journals have published more than 1000 peer-reviewed journals in support of its reliability. But perhaps of more interest are the following case histories.

Case history 1: J.C. presented with symptoms of fatigue, lethargy, joint aches and excessive hair loss (at age 25). His hair mercury was markedly high. Following treatment his hair levels of mercury decreased to a much more acceptable level and his symptoms improved significantly. The source of the toxicity was never identified.

Case history 2: C.T. became mentally ill and was diagnosed with paranoid schizophrenia. He was also alcoholic and consuming large quantities of drugs. An HMA revealed four times the acceptable levels of lead in his hair and also elevated levels of cadmium, mercury and copper. Following therapy and supplementation his condition improved dramatically, he lost his cravings for alcohol and his symptoms of mental illness reverted to normal, with no further need for psychoactive drugs.

Case history 3: L.S., a housewife in her early 40s, had been feeling tired for months. Her doctor had run all the standard tests and could find no problems. Finally she had an HMA which showed she had high levels of lead that were causing her tiredness. The cure came easily, she was feeling better in two weeks and the tired feeling vanished within a month.

L.S. was breathing excess lead from a car exhaust. How much lead are you breathing in from car exhausts - jogging or queuing in heavy traffic? How much cadmium have you accumulated from passive (or active!) smoking at the office and the pub? If you have dental fillings that contain mercury, have you ever wondered if the mercury vapor could be gradually poisoning you?

Why might you benefit from an HMA? If you have a disease or illness that has not responded to conventional treatment, you may wish to explore other possibilities and an HMA is an excellent place to start. If you are suffering from "unexplained" problems such as headaches, backaches, weakness or tremors, an HMA could help you to get to the bottom of it.

If you can answer 'yes' to five or more of these questions an HMA may provide information which, if acted upon, could benefit your health.

* Do you live in a city or by a heavy road?

* Do you spend more than 2 hours a week in traffic?

* Do you exercise or walk by busy roads?

* Do you smoke more than 5 cigarettes a day?

* Do you live or work in a smoky atmosphere?

* Do you buy foods exposed to exhaust fumes (i.e. on display at a road-side stall)?

* Do you generally eat non-organic produce?

* Do you drink more than 1 unit of alcohol per day? (1 glass of wine, 1 pint of beer or 1 measure of spirits)?

* Do you spend a lot of time in front of a TV or VDU?

* Are you exposed to pollutants in your job (e.g. printing, dentistry) or hobby (gardening)?

* Do you have two or more amalgam dental fillings?

* Do you usually drink unfiltered tap water? Or you may just be feeling under par without knowing why.

Are just toxic minerals examined? No - the HMA will examine the status of the essential minerals such as calcium, magnesium, zinc, chromium and a whole host of others. Modern food processing methods strip nutrients from food.

Did you know that a massive 98% of chromium is stripped from flour in the refining process. Not heard of chromium? It is an essential part of the 'Glucose Tolerance Factor' which controls blood sugar, stimulates burning of food for energy, controls blood cholesterol levels, reduces blood fat levels and suppresses hunger symptoms.

Modern farming methods have also depleted the mineral content of soil, and addition of some fertilizers can make minerals unavailable to plants. But it's not just deficiencies that can cause problems. You can have too much of anything! If calcium (in dairy products), sodium (in table salt) or phosphorous (in fizzy drinks) are present in excess in your diet, these can upset the natural mineral ratios. And interactions between minerals are important too. Is fluoride in your water supply depressing your calcium absorption? The graphs in an HMA will reveal all. Why not find out?

Obviously an HMA is no substitute for diagnosis by a qualified medical practitioner, but if conventional medical investigations have failed to find a reason, or suggest a treatment for your problem, HMA represents an invaluable and cost effective next step.
