Abstract

The most common causes of food allergy vary among countries according to the dietary habits and the frequency of consumption of foods. Legumes are important sources of protein that are widely consumed all over the world. The legume family includes lentils, chickpeas, beans, broad beans as well as peanuts and soybeans. Skin prick tests are generally considered safe. However, systemic reactions may develop during skin prick testing, Systemic reactions from skin testing are more frequent with food, drug, latex and venom allergens. Systemic reactions occur more frequently after prick to prick tests that are performed with fresh food than those with standard extracts. This paper reports a case with a history of anaphylaxis to lentils and peas. The patient was found to have type 1 reaction to chick peas, broad beans and green beans although she did not describe a reaction to these legumes in her history.
