One in five people suffer from allergies, making it one of the most common chronic medical complaints today. The word allergy means "altered working," and an allergic response in a simplified sense is an adverse or inappropriately amplified immune system response to something that many other people find harmless. Allergies can be inconvenient, as oftentimes an allergic reaction expresses itself as a headache or fatigue, itchy eyes, a runny nose,  or a skin rash, although some people suffer more severe allergic reactions particularly associated with nuts and seafood. Diet plays a crucial role in supporting your overall immune system, which can help to minimize the occurrence or the severity of an allergic response. Following your specific Blood Type diet, GenoType diet or SWAMI protocol is the first step in allergy management. Additionally, Dr. Peter D'Adamo has designed a full line of formulas which provide relief for occasional or chronic allergic responses.
