Abstract

Food allergies can affect both people and animals, and the number of food allergies not only in human but also in animals has increased. Food allergies can affect a patient’s quality of life and lead to a loss of pleasure in eating. There are many kinds of food in the world, and it is possible for all people to have food allergies. The kinds of food allergy differ depending on country, nationality, age, and religion. For example, peanut allergy is common in western countries, but in Asia, it does not occur as frequently. And the incidence of egg allergy in children is higher than that in adults. Not all food allergies in childhood continue into adulthood; in some cases, the symptoms often improve with age, so-called allergy march. In case where food is restricted by religion, the number of its foods allergy must be rare. Food allergies of childhood have close relation to growth and development; this is a serious problem for not only patients but also their families and educational institutions. In some countries, information regarding and measures against food allergy are inadequate. Because religion, economy, education, and nationalities are different, addressing these inadequacies will require large amounts of time and effort.

Occupational food allergies affect a patient’s life and occupation. The avoidance of foods that cause allergic reactions during only meals can not resolve the problem of occupational food allergy; if other workers in the same office do not understand the allergy, a patient’s symptoms are going to progress, finally food allergy causing them to resign from their work. Economic and productivity loss due to food allergy are huge; a response is therefore needed to problems of allergy in the office and on social ground (Sugiura K & Sugiura M. 2010a). Recently, the number of pets with food allergies has been increasing. Basically, food allergy in pets is similar to that in humans with regard to symptoms, examinations, treatment, and safety measures. Because animals do not speak, it is often difficult to diagnose animal food allergy. Most of the food allergies in animals show as red spots, scratching, runny nose,
