Yes & No. yes the body can react to food internally. No because it is not a "big" enough reaction for the medical field to classify it as an allergy.
A RAST test for IgG can determine to what extent the body is reacting. Problematic foods are graded on a scale of 1-4. 4 is a life threatening allergy. 1 -2 are considered a sensitivity. 3 is a potential allergy.
Any foods falling into the range can cause problems internally & behaviorally.
