Food allergies affect an estimated 10 to 12 million people in the United States. Some of these individuals can develop life-threatening allergic reactions when exposed to allergenic proteins. At present, the only successful method to manage food allergies is to avoid foods containing allergens. Consumers with food allergies rely on food labels to disclose the presence of allergenic ingredients....

The last two years have seen the publication of 3 major guidelines on the diagnosis and management of food hyper-sensitivity (FHS) [1–3]. These guidelines have highlighted important issues in dealing with those with FHS, primarily food allergies. Dealing with adults and children with food allergies requires the healthcare professional to have an understanding of the immune mechanisms involved i...

BACKGROUND Studies suggest that individuals of low education and/or income, new Canadians (immigrated <10 years ago), and individuals of Aboriginal identity may have fewer food allergies than the general population. However, given the difficulty in recruiting such populations (hereafter referred to as vulnerable populations), by using conventional survey methodologies, the prevalence of food al...

Peanut and tree-nut allergies have increased dramatically in prevalence, especially children. Historically, children with food been treated through strict avoidance of the allergen. Recently, an oral preparation peanut allergen (Palforzia) was approved for immunotherapy (ie, desensitization) 4 to 17 years old. This article reviews its role allergies.

The last 10-15 years have seen a steep rise in food allergies in westernised countries. South Africans, especially those of black descent, have traditionally enjoyed a low rate of food allergy and have long been thought to be protected against the food allergy epidemic. Previous food allergy prevalence studies in South Africa have focused on sensitisation and questionnaires which are not a true...

This article reviews possible risk factors and theories for the development of food allergy. It is noted that previous strategies to prevent food allergy through allergen avoidance during pregnancy, breast-feeding, and infancy have more recently been called into question. Alternative hypotheses are examined with respect to food allergy, namely the hygiene hypothesis, the dietary fat hypothesis,...

Clinical classajication of food allergy Food allergy has become a contentious subject. True food allergy is dependent on evidence of intolerance to a specific food-in other words recurrence of symptoms on two or more occasions when that food is taken (preferably blind and in the presence of the doctor). There should also be direct or indirect evidence of an immunological component to that react...

Double-blind placebo-controlled food...

i m m r m ( w m f k T i i h a I t a i f I f t r h n R eactions to foods are extremely common and the etiology of these reactions determines their correct management. Adverse food reactions re not all allergic. The management of food adverse eactions ranges from complete avoidance of minute mounts of food to ingesting milk after lactase suplementation. It is, therefore, important to accurately l...
