This is one way food allergies develop. There are other ways, also. E.g., via inhalation of food particles in the air. The quantity of proteins in the air from food is much smaller, but the food gets "processed" by the airway. Those with Asthma or Allergic Rhinitis have inflamed, thus leaky, mucus membranes in their airway. A leaky membrane allows the inhaled food proteins to interact with the immune system directly, thus generating antibodies.
Food allergies can also develop if one has underlying leaky gut from candida infection, inflammatory bowel disease, celiac disease, gastrointestinal dysbiosis (SIBO, etc.), etc. The leaky gut allows whole or semi-processed food proteins to go through the intestinal wall and interact with the immune system directly, thus triggering antibody formation. HCl supplementation won't correct this type of issue - an Integrative or Naturopathic Physician may be able to help.
