aPatients often reported more than one food as being responsible for the allergic reaction described in their survey, so the numbers in this column may add up to more than the number of patients reporting the allergic reaction. For example, some patients reported green pea alone as being responsible for their reaction, whereas some reported both green pea and lentil
