  • If benefits are felt after this exclusion, a gradual introduction of one food at a time, leaving at least 4 days between each reintroduction, will allow you to identify those foods that should be left out altogether – if symptoms reappear when they are reintroduced.
  • If a reaction occurs (symptoms return having eased or vanished during the 3-week exclusion trial), the offending food is eliminated for at least 6 months and a 5-day period of no further experimentation follows (to clear the body of all traces of the offending food), after which testing (challenge) can start again, one food at a time, involving anything you have previously been eating which was eliminated by the oligoantigenic diet.

CAUTION: When a food to which there is a strong allergic reaction occurs, especially one which has been consumed regularly in the past, is stopped, the individual may experience ‘withdrawal’ symptoms for a week or so, including flu-like symptoms and marked mood swings, anxiety, restlessness, etc. This will usually pass after a few days, and can be interpreted as a strong indication that whatever has been eliminated from the diet is responsible for a ‘masked’ allergy, which may be producing many of your symptoms.
