This is the prototypical ultra-processed food because it started out with corn. Corn is the first ingredient. Does this look anything like corn to you? No. Not so much. Industrially processed. Yeah. It's got real food in it. It has corn, vegetable oil, but then it has corn maltodextrin as the third ingredient.

I don't have that in my kitchen, and I cannot buy it at my local grocery store. These foods are processed to make them. A lot of people use the word addiction.

These foods were deliberately designed to be profitable.
