Allergy means altered or abnormal tissue reaction after exposure to an antigen (also called allergen). Allergic reactions occur if the body tissues are sensitive to allergen. Allergic reactions are caused by wide variety of substances and conditions. We have seen a rapid rise in incidence of food allergy in recent years. Oral allergy syndrome is now the commonest food allergic manifestation in adults. There are wide variety of foods that cause allergy like milk, eggs, vegetables, fruits, sea foods and meat etc. Since they are commodities consumed almost daily so, there is a need to know which one is the most allergic and what symptoms do they cause during allergy. There are various causes of these allergies like natural salicylate in foods, lactose, amino acids. Apart from growth of pests and molds also lead to allergic reactions which reach out body by various means. The survey conducted by me was depicted the quite often we do not hear complains of allergic reactions. Out of the 105 respondents 33.43% population was found to be allergic and rest were non allergic. The standard deviation was calculated to be 11.89. The common allergic foods were sea foods, milk and wheat. The most common test used to detect was skin prick test. It is not believed that adverse food reactions are responsible for many undiagnosed health complaints. As a result numbers of health practitioners are using allergy avoidance diets to identify food allergies and food intolerance in their patients so; allergy is a current topic of discussion. The research will help me find out the most common allergy causing foods and their effect on human body.
