No, if you process something minimally like Kimchi it is not bad. In fact fermented foods are generally seen as good for you. Yogurt, cheese as well.

So Kimchi is considered minimally processed. Flour has various processing levels to make bread. Enriched white is strictly worse than others.

Cookies with hydrogenated palm oil would be bad. Any oils beyond cold pressed extra virgin olive oil are supposedly bad.

Now the preservatives in store bought kimchi could theoretically be a bigger issue.. I don't know how many folks have studied them. I imagine they just pass through us but probably influence the microbiome etc...

Canned foods are worse than fresh or frozen.
