In this essay I have investigated how two families, with children, who have food allergies, experience what support and what treatment they get in preschool for their difficulties. I have interviewed two children and two parents. The study shows that the interviewed parents believe that more knowledge in the community and among staff in preschool, about food allergies, is needed. Parents wish that the staff should write an action plan that describes how to deal with children who have food allergies and that preschool invites parents and children to record results. It is important to consider an inclusive attitude so that children don’t feels excluded. There is some research going on around this subject and researchers agree that the incidence of food allergies in the society is growing, but that it is difficult to be able to present a certain theory why, and what the underlying factors are. The most probable cause can be our hygiene, our many times excessive cleanliness, we do not get in contact with enough bacteria, which upsets the balance of our immune defence. Our immune system gets too little stimulation of bacteria, and as a result, food allergies can occur. Progress in science today offers some opportunities to understand the origin behind food allergies but knowledge is inadequate it is not known what factors contribute to sensitization and development of the regulatory mechanisms of the individual as to why an allergic reaction occurs or not allergic reaction occurs or not.
