I recently came across this very interesting list on the Calgary Allergy Network's (CAN) website. CAN is a local organization affiliated with the Allergy/Asthma Information Association of Canada.
Often times, when someone is allergic to a food, they are allergic to other foods in the same food group. While we are not able to assume that because you are allergic to peanuts that you may also be allergic to all beans, this is true for some people. I have found that foods which cause major reactions for my angel are in the same family as some of the foods that cause more manageable reactions. AS a resource for parents, CAN has published a list which includes a foods by their common names and the family of foods to which each belongs. They have also listed some of the common cross-reactors such as those for people allergic to birch or Mugwort.
I found this link quite interesting and of particular assistance when I am trying to better understand why my angel might be allergic to certain foods. I hope that it is helpful to you, as well.
