A rotation diet is sometimes recommended to prevent some individuals from developing new allergies as a result of eating the same foods regularly. The idea is to vary the kinds of foods eaten on a regular basis to reduce the exposure to a potential allergen, hopefully preventing the development of new allergies. If the individual is used to eating a potentially problematic food everyday, when switched to a rotation diet, the individual should try eating the food only once in four days. If sensitivity to wheat is suspected, the individual should rotate wheat-containing foods into their diet every fourth day. By lessening the consumption of problematic foods by rotating the schedule when they are consumed, the symptoms triggered by these foods can be reduced.
