For anyone who has a corn allergy, knows it's a daunting task. Foods such as: breads, pastas, yogurts, soft drinks, ice cream... Yes,..the list goes on,(including G-free foods).... all contain corn syrup or some derivative of corn such as: fructose or maltodextrin. Even the humble condiment, ketchup is made with corn syrup and high fructose corn syrup.
Thanks to the anti-HFCS(High Fructose Corn Syrup) movement, there are lots of organic or corn-free ketchup's on the market. I've even discovered a brand made with agave syrup.
