A food allergy is an immune system reaction that occurs soon after eating certain foods. Even a tiny amount of the allergy-causing food can trigger signs and symptoms such as digestive problems, hives or swollen airways. Allergies have the potential to be life-threatening in severe cases. An intolerance is generally less serious with the most common symptom being delayed digestive problems. Although this reaction is less severe it is something we take seriously as the health and well-being of our customers is our priority.
