Most salted nuts have corn starch added to make the salt stick to them. Also, a lot of vitamin C has been made from corn. Nutribiotic has a non-corn, non-GMO version. Sodium Ascorbate is the way to go. Oh, and also, corn is in most things that have "citric acid" added (or ascorbic acid). Some citric acid is made from mold, but a lot of it is from corn syrup. Fructose is also corn derived usually.
