Food Labels 101: The Many Names for Soy

27 Jul

I’ve been asked by a couple of folks for information on how to identify if there’s soy in a food product when reading the ingredient list. Sure, if it says “soy,” then it’s easy to tell that the food is a no-go, but what about all the hidden sources of soy that are in everyday food products? Luckily, as of January 1, 2006, foods that are covered by the FDA labeling laws must be labeled in plain English to declare that it “contains soy”  if there is a soy ingredient in the food or product. Unfortunately, there are many foods that are not covered by FDA allergen labeling laws, so it is still very important to know how to read a label to identify soy ingredients.

I’ve been compiling a list for some time now that I hope you find helpful. It is by no means a complete list and I will provide updates as I learn more, but in the meantime, I hope you find it useful when you’re scouring food labels and trying to determine if a food contains soy ingredients.
