Well, while that saying was often misused, it's highly applicable in this case. Here, what's suggested in the original post is highly processed foods cause cancer. But consider for a moment the demographic who may be eating, on the whole, the most ultra processed food? The poor. With lack of access to proper nutrition and medical care. So I'm not bought in 100% that the ingredients of ultra processed foods, by itself, is what causes the cancer.
This is always my concern with dietary studies as well, it in this case it seems like they took a group of people and randomly assigned them to eat either highly processed foods or non-highly processed foods for a few weeks, so that solves some of the correlational issues, but I still think that the conclusions you can draw from such a short term study are limited.
