The NIAID provides Food Allergy: An Overview (PDF | 5.6 MB), which discusses the difference between a food allergy and a food intolerance. In addition, it explains that individuals who suspect they have food allergies should have them identified by a healthcare provider because unidentified food allergies can potentially cause serious reactions.
