GM Soy Resists Essential Protein-Digesting EnzymesThe longer proteins survive in the digestive tract, the more time they have to provoke an allergic reaction. Mice fed GM soy showed dramatically reduced levels of pancreatic enzymes.
When protein-digesting enzymes are less available, food proteins last longer in the gut, allowing more time for an allergic reaction to occur. A reduction in protein digestion due to GM soy consumption could promote allergic reactions to a wide range of proteins, not just to the soy. No human studies of protein digestion related to GM soy have been done.
Soy's Little-Known Link to Peanut Allergies
There is at least one protein in natural soybeans that has cross-reactivity with peanut allergies.10 This means that for those who are allergic to peanuts, eating soybeans could trigger a reaction.
It is certainly possible that the unpredicted side effects from GM soybeans might increase the incidence of this cross-reactivity. But it is unlikely that it has been researched. GM soy was introduced into the U.S. food supply in late 1996.
We are left only to wonder whether this influenced the doubling of U.S. peanut allergies from 1997 to 2002.
