According to the medical expert who examined this item, there is convincing evidence that persons in the UK with severe allergies to vegetables are in the minority, with the majority falling into category 1 or higher (pollen food syndrome). However, there has been very little study to back this theory. Further research is needed to verify it. The first vegetable allergy was reported in 1884 by the English physician James Richard Allport who described such reactions to carrots and potatoes. In 1938, the American physician William Cole reported a case of anaphylaxis following consumption of a tomato sandwich. In 1950, the British physician Frank Burrascano coined the term "plant food allergy" to describe these disorders. Since then, more than 100 cases have been reported in the medical literature. Most patients were children at the time of diagnosis; only a few adults were identified. The most frequent plants involved were peanut, celery, mushroom, shellfish, and fruit. Although there have been reports of allergies to vegetables such as cabbage, brussels sprouts, cauliflower, kale, kohlrabi, and green beans, these appear to be rare. People with plant food allergies can experience symptoms when eating certain fruits, vegetables, weeds, trees, bulbs, and flowers.
