Up until now I have been able to eat Lay's Kettle Cooked plain potato chips because they weren't cooked in corn oil. They have reformulated their product and now "corn oil may be used." I e-mailed the company and this is the reply I got,
"Martha, the corn oil we use to cook our chips has gone through a heated cleaning process that removes the protein residues. When an individual has an allergy, they are allergic to the protein in the offending food. With the protein removed, most corn allergic people can eat snacks made with this oil.
We also make Lay's Natural Thick Cut potato chips cooked in expeller pressed sunflower oil. You'll find this in the natural food section of most grocery stores.
We consider you a valued consumer and hope you will continue to enjoy snacks from Frito-Lay."
The thing is, the jury is still out on the heated cleaning process actually removing all the allergy causing proteins. I KNOW I've had a reaction to corn-oil cooked chips. The key word is "most corn-allergic people."
I'll look for the natural thick cut chips, but in our rural area some products aren't available. In the meantime I'm eating another brand of kettle chips but I don't like them as well as the Lay's.
Not worth my well-being to take them at face value.
