A food allergy occurs when the immune system wrongly detects certain foods as harmful substances. The body responds by producing histamine, a chemical released by the white blood cells that plays a role in causing allergic reactions and inflammation symptoms. This leads to symptoms such as rashes, redness, itching, swelling, and raised bumps on the skin<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK447107\/\" target=\"_blank\" rel=\"noreferrer noopener\">1<\/a>,<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/27795547\/\" target=\"_blank\" rel=\"noreferrer noopener\">3<\/a><\/sup>.
