Any food can cause allergy. Mast Cells are cells inside the human body that line all of the surfaces of the skin, mouth, nose, sinuses, lungs and intestines. Mast cells have histamine inside of them. Everyone has mast cells, but not everyone has the allergy fuses to make the bombs go off. Histamine causes itching, sneezing, swelling and a flood of mucus in the nose, itching, burning and swelling in the skin, headaches and plugging up of the sinuses, spasms and wheezing in the lungs, and also, cramps and diarrhea in the stomach.
Antihistamine blocks the bad effects of histamine.
Some antihistamines make people sleepy since they get into the brain and affect its functions. Newer antihistamines do not get into the brain, and therefore, do not have this side effect. Immune System is the part of the human body that helps to fight infections. Antibody is the part of the human immune system that can attach itself to bacteria and viruses and cause them to die. Antibodies are normally found in the fluids of the body including the blood, tears, mucus and other fluid secretion.
