I don't buy anything pre-made, generally. If it's not seed oil it's HFCS or some other garbage ingredient. I 98% just buy ingredients themselves. The bread I buy is whole wheat and I've just confirmed that it does not have seed oils.

The thing is, I'd like to stress that I don't go out of my way to do this or expend much extra effort. It's not a burden to eat a potato instead of a cup ramen or something. People just don't care about their health and buy every trash food they see.
