This is a self-help system designed to track down food allergies. You take out those foods and drinks which are most likely to be indicated in food allergy and follow the hypo-allergenic diet for about two weeks. The diet is reproduced here by kind permission of the Society for the Promotion of Nutritional Therapy.
You may eat:
All fresh vegetables. Includes raw vegetables and salads, lightly steamed or stewed vegetables, soups made with fresh vegetables, potatoes (without butter). Frozen vegetables. Do not use tinned vegetables except for pulses.
All fresh fruits and pure fruit juices. Tinned fruit is occasionally allowed if it contains fruit juice with no sugar rather than syrup.
All fresh or frozen fish. Oily fish like mackerel, herrings and sardines are especially recommended. Tinned fish is acceptable if in pure oil, brine or spring water.
All fresh or roasted nuts and seeds (unsalted). Includes almonds, brazils, walnuts, cashews, hazelnuts and pecans. Sesame seeds and linseeds need to be ground up first otherwise they just pass straight through you. Other seeds to include are sunflower seeds, pumpkin seeds, pine kernels. Tahini (sesame seed paste) and other nut butters are fine as long as they are sugar- and additive-free.
All pulses. Includes lentils, chickpeas, kidney beans, butter beans, haricot beans, aduki beans. You can cook these yourself or buy canned. If you are cooking kidney beans and chickpeas, remember they need to be soaked overnight. The soaking water should then be discarded and the beans cooked very thoroughly in fresh water. Check that canned beans do not contain sugar or anything else except salted water.
All soya products. Includes tofu, soya milk, and miso. Use tamari instead of soy sauce for flavoring as it is wheat-free but soy sauce is not; and sometimes soy sauce contains MSG (monosodium glutamate) which should be avoided.
All cold-pressed (unrefined) oils. Includes sesame, sunflower, extra-virgin olive oil. The supermarket oils (except extra-virgin olive oil) often contain anti-foaming agents and other chemicals added in the processing to extract more oil and should be avoided.
Non-gluten grains. Includes brown rice, millet and buckwheat, as well as flours and flakes made from these grains. Since grains are very small they can absorb more pesticide, so try to buy organically grown ones if available. Use arrowroot or corn flour as thickeners.
Pure herbal or fruit teas. Includes peppermint, chamomile, rosehip, etc.
Natural sweeteners. Honey (in small amounts), maple syrup, rice syrup, date syrup.
