Part of what is wrong with America. Get rye or pumpernickle bread from a real bakery. Don’t use peanut butter or ketchup - that’s children’s food. As for drinking soda, all I can say is bless my strict parents for never having it in the house - I never developed a taste for it.
Its not too hard to find bread without corn syrup, by checking the labels. I have found that the store brand peanut butter often has no corn syrup, and now some major labels have ‘corn syrup free’ varieties. I disagree with the characterization that its children’s food - its cheap, cheap, protein.
My parents never let me have soda either. but somewhere along the way I developed a taste for it....in moderation. But I wouldn’t mind if I were to never drink a soda again.
Now, if you want some examples of more ‘adult’ foods that have corn syrup - there’s salad dressing, worcestershire sauce, some pickles, barbeque sauce, shrimp sauce, flavored yogurt, and even soup.
I see the endless trains of black tanker cars, with bright yellow ears of corn on the side, traveling back and forth on the rails every day. Corn syrup is big business. Unless you do most of your cooking from scratch, you probably consume some every day.
