Food Families

I have been asked many times by people with food allergies about which foods are related to which foods. I hope this list is helpful. Allergy to one member of one family of foods often means allergy to other members. This is especially true of certain families (legume, citrus) but less so to other (Mammal family.)  The names in bold below are the scientific classification families to which the food belongs.  [I revised and improved this list on 1/10/11, so I apologize for some differences.]

SEA FOODS BY CLASS (this is 2 groups above families )

Bivalvia: clam, mussel, oyster, scallop.
Cephalopoda: octopus, squid.

ANIMAL FOODS
Bird: All fowl and game birds: chicken, turkey, duck, goose, guinea, pigeon, quail, pheasant, etc.
Although egg belongs to this family, it does not seem to be related to chicken meat allergy.
Reptile: These are eaten very little, but it is interesting that frog, turtle, and rattlesnake meats are available.
Mammal: Beef, pork, lamb, rabbit, squirrel, venison, etc. Cow’s milk is of the same animal origin as beef. Most persons allergic to cow’s milk cannot tolerate the milk of other mammals such as goat. I recommend using a vegetable source for milk.
