Chasing down the culprits may require the services of a doctor. Theories of why the incidence has increased include:- Increased stresses on the immune system (such as greater chemical pollution in the air, water, and food).
- Earlier weaning and earlier introduction of solid foods to infants.
- Genetic manipulation of plants resulting in food components which cross-react with normal tissues.
Signs & Symptoms Most food reactions are delayed up to several days and are thus more difficult to identify.
Diagnosis & Tests There are basically two methods of detecting which foods may be causing symptoms.- Experimentation. Going on an elimination diet (fasting, or consuming foods which have a low allergic rate such as rice, lamb, cabbage) for 4-7 days until symptoms clear. Reintroducing foods one at a time may point to the culprit. An elimination diet can be accurate, but difficult at the same time.
- Food allergy testing. Recent improvements in laboratory techniques have made blood testing more reliable. Costs for the tests run from $130.00 to $300.00 for 90+ foods, but can be a valuable and time-saving approach.
