Great question: Unfortunately, the exact reason people develop nut allergies is unclear. It is likely a combination of being genetically predisposed and environmental exposure. One theory is early exposure to lotions or oils containing nut protein applied to infants who have thin skin or eczema. The nut protein is absorbed and body senses it as "abnormal" and make allergic antibodies. Why in adults? Not sure.
