How it works

Food intolerances are non-immunologic reactions arising from enzyme deficiencies or gut dysfunction, not from immune activation. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
A food allergy is an immediate, reproducible IgE-mediated immune response in which the same exposure will provoke a reaction every time. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
The IgE immune response clears within approximately 1–2 days of last food exposure. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
Food sensitivities involve IgG-mediated delayed hypersensitivity with a clearance half-life of 22 to 96 days, meaning strict elimination is required for weeks to months before symptoms abate. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
Roughly 10% of the US population has true IgE-mediated food allergies. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
Approximately one-third of the US population has some food reaction, though this figure is likely an underestimate due to the absence of agreed-upon diagnostic criteria. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
Withholding allergenic foods like peanuts in infancy may paradoxically increase allergy risk later in life. — Food Reactions and Mood: Mechanisms, Evidence, and the Gut-Brain Axis
