To avoid eating soya, you have to stop eating:
Soya flour
Soya milk
Soya beans
Tofu
Soya oil TVP
Soya sauce
Miso
Soya, in its various forms, is found commonly as an ingredient in processed foods (e.g. pies, bakery, prepared dishes). Read labels to see if any of the above products are mentioned. If a product contains vegetable oil of unspecified nature, it can often be soya oil. Avoid this. If it contains vegetable protein, this is invariably soya, and should be avoided.
Lecithin is sometimes derived from soya and sometimes from eggs; products containing this (e.g. ice cream and margarine) are best avoided to be absolutely sure.
Many breads now contain soya flour as well as wheat flour. You will not know this if you buy unlabelled bread from a local baker or wholefood shop. Check with them as to what ingredients they use. Avoid bread if you are not sure whether it contains soya or not.
If you are chemically sensitive, you may react to the water used to make up processed soya milks rather than soya itself .

In intra-dermal tests, a higher dose of allergen extract is introduced just under the outer skin using a syringe. A similar weal and flare response within 10-15 minutes indicates a positive reaction. In addition, you may get a late skin reaction – a raised red swollen bump around the test site – about five or six hours later. Sometimes there may be a late skin reaction on the following day.
The infra-dermal test is much less commonly used in the UK than the skin-prick test. It can be painful, it has a slight risk of adverse reaction, and some people feel unwell on testing. It can, however, be useful in that it can detect positive reactions where skin-prick tests have previously been negative.
Patch tests are used to confirm a diagnosis of contact dermatitis – a delayed allergic skin reaction to something you have touched. Patch tests can be very useful in identifying specific things that you can then avoid. Small patches containing a range of common allergens, mostly chemicals, are attached to the skin, usually to the upper back. The sites of the tests are marked on the skin. The patches are left there for 48 hours, and then removed.
The sites are examined for reaction and then left unwashed for a further 48 hours, when the sites are examined once more. A raised red bump at the site of the allergen is an indication of positive reaction. False positives and false negatives can result, so once again patch tests are used mainly to corroborate a case history. You can use patch tests to test specific things you suspect – for instance, a fabric, a leaf or a chemical you use at work or school. You can also do a home version of the patch test for yourself.
Anti-histamine drugs block the release of histamine and can interfere with skin test results. Such drugs should not be taken for several days before testing.

If you are exceptionally sensitive to resins, wear wool, pure silk or pure synthetics if possible. You can buy resin-free cotton clothes -usually called ‘formaldehyde-free’ – for babies, children and adults. Sources are given below.
You can also find certain kinds of cotton clothes that are much less highly treated than others. These are often well tolerated even if you are sensitive to resins. If you are unable to wear wool, silk or synthetics, and want to have a wider choice of cotton clothing, choose relatively untreated cotton clothing as follows:
Try
Avoid
Take care with
Cotton jersey
Cotton poplin
Brushed cotton
Cotton fleece
Cotton drill
Cotton lawns
Cotton corduroy
Denim
Cotton voiles
Cotton towelling
Easy-care
Knitted cotton sweaters
Permanent Press
Indian cottons
Sanforised
Third World cottons
Wash New Clothes
Resins wash out readily, but not all fabrics or clothes are washed during manufacture, and new clothes can have very high levels of fumes. You can reduce the level to tolerable amounts by washing new clothes before wearing them. If you add a dessertspoonful of sodium bicarbonate to the water, this also helps to neutralise the resins. You may have to wash new clothes several times before you can wear them, but, for virtually everyone, this is sufficient to avoid any major problems. Unless you are extremely sensitive washing clothes well will make resins tolerable.

Synthetic and latex materials are conventionally described as non-allergenic and are often recommended by doctors in the belief that they do not cause allergy and that house dust mites do not thrive in synthetic materials. This advice is misleading. Synthetic and latex are useful as an alternative to wool and feathers, which commonly cause allergy, but people who are chemically sensitive often react to synthetics and latex (including plastic mattress covers as well as the bedding itself).
Synthetics and latex also harbour dust mites. To thrive, mites need warmth, moisture and human skin, bacteria or moulds as food. Bedclothes, pillows and mattresses of synthetics and latex provide these just as natural materials do. Some synthetic bedding can be washed and this helps in controlling dust mite allergy in that the mite’s faecal pellets (which are for most people the allergens) are washed out. But mites are not themselves killed by washing at the low temperatures necessary for virtually all synthetics. So they can survive the wash and continue producing faecal pellet allergens. Synthetic and latex bedding are therefore not an automatic choice for people with allergies and chemical sensitivity. They are a good choice if you are:
• allergic to wool, feathers, cotton or other natural fibres
• not chemically sensitive
Do not use a plastic or vinyl mattress cover even if you do not react to plastics. It prevents the mattress airing, keeps in damp and aggravates house dust mite problems. Use a small plastic sheet under the area that needs protection against bedwetting.

If you want to keep a dog, some breeds are reported to be less troublesome than others. Allergy is very idiosyncratic, however, and these may not work for you, so take care. Many people with allergies say that dogs that require a lot of grooming are more likely to cause reactions than dogs that do not, because more hair is shed and more contact is necessary. Dogs that have shorter, wiry hair generally shed more dander than long-haired dogs, but dogs with soft, curly hair, such as small poodles’ are sometimes found to be less provocative.
If you are blind and have to keep a guide dog, it may be best to choose a type of dog that sheds less hair, or needs less grooming, such as curly-coated retrievers, or cross labradors.
Be careful with children and animals at school. Small mammals are often kept in schoolrooms and these may be responsible for your child’s reactions. School cats are also often allowed to roam out of school hours and can leave allergens to upset the exceptionally sensitive. Watch out for the ‘school run’ if your child travels regularly in a car in which dogs travel.
