Confusion can arise from the fact that there may be pharmacological effects masquerading as an ‘allergy’. For example, the headache, flushing, racing pulse and giddiness that can come on after too much caffeine is really a drug reaction, not an allergic one. Obviously individual variations in trigger thresholds make this one sometimes hard to observe. Few people understand the incredible range of pharmacological substances that are to be found in plant substances. Most “green-minded” people think of herbs as kind, nurturing and gentle: wouldn’t hurt anyone, right? But, hey, I like to point out that foxglove, hemlock, opium poppy, marijuana, deadly nightshade and countless plants stuffs are dangerous, even poisonous. “Beware the humble carrot” wrote Richard Mackarness; this innocuous looking vegetable contains a neuro-toxin. Not relevant? I had a patient in the 1980s, a young boy, who had epileptic fits every time he ate carrots or anything from the same food family: parsnip, celery, parsley, dill, fennel, coriander etc.

Do your ears swell up when you wear certain types of jewelry?  You might have metal hypersensitivity and these fall into several categories and sources: Metal pollution Then there is the matter of hypersensitivity to metals such as nickel and chromates. These are cell-mediated immunity reactions, without antibody involvement. These too are probably best not called allergies, but clearly there is a sensitization effect that fulfils the prescription of the von Pirquet phenomenon. Don’t forget too that metals can be poisons as well as sensitizers. Mercury and lead are pretty obvious poisons, but so are aluminium (from cooking), cadmium (from tobacco), thallium (rat poisoning and industrial exposure), zinc and iron smelting wastes are EPA regulated toxic materials yet are sold and used legally as fertilizers. There are many other potential metal poisons and it has been my contention for some years now that what I call “metal pollution” may turn out to be a far more serious hazard than chemical pollution, such as pesticides and atmospheric pollution.

Over time it has become obvious that some individuals are sensitive to environmental chemicals. It is hard to describe this as an allergy; probably the term ‘low-grade poisoning’ would be better since many of these chemicals would make anyone exposed to them in sufficient concentration feel ill. The problem is just that certain individuals react to smaller doses. We are all subject to a barrage of alien chemicals in our bodies (Greek word: xenobiotics, meaning alien to life). We have chemical pathways in our bodies designed to remove toxic substances: a process called detoxication or biotransformation. The trouble is these new man-made chemicals have no equivalent in nature and so we do not have the right systems in our body to fully eliminate the toxicity. In fact, in its attempts to deal with the problem the body sometimes, by mistake, actually coverts these xenobiotics into something even more toxic (Casarett and Doull’s Toxicology. Basic Science of Poisons. Third Edition, Editors: Klaasen CD, Amdur MO, Doull J, Macmillan, New York 1986).

Probably no recent development in the study of allergy has caused more confusion than the recognition of the multiplicity of symptoms it can produce. No doubt this has hampered progress, since the traditional medical view of patients with many and variable symptoms has always been that they were somehow neurotic and ‘putting it all on’. […]

For most people the problems of exclusion diets are few. Withdrawal symptoms, extra expense or the sloth encountered in changing the habits of a lifetime are the main difficulties. However, three situations require extra comment: CHILDREN Children have more food allergy problems than adults. Yet food is vital to them; their growth will be stunted […]

The US Food and Drug Administration has recognized that approximately 1 in 100 people suffer from sulfite allergies. For asthma patients, that rises to 1 in 5. A variety of foods contain sulfites as an additive, primarily an anti-oxidant, to prevent discoloration and also a sterilizing agent – these are recognized on the label as […]

The role of salicylate (aspirin-containing) foods in hyperactivity (ADD/ADHD) in children was first put forward by Dr Ben Feingold. He claimed dramatic results from a diet free of these foods. Feingold diet 1: Foods Containing Salicylates All fresh meat, fish, shellfish, poultry, eggs, dairy products, cereals & bread are low in salicylates. Feingold later improved […]
