Will Processed Food Kill You?

We get these disturbing posts on our phones these days. I think of them as "horror clickbait," stories that are so disturbing we have to read more. I can't do anything about many of the stories, but I can help a little with the ones to do with our health. The clickbait story was that processed food will shorten your life . By how much?

" When testing for trend in survival rates between the three Cbl level groups, we observed trends toward lower survival with higher Cbl levels for all three follow-up periods for both patients with localised and non-localised cancer. The differences in survival with higher Cbl levels were similar after 2, 5 and 10 years" ( https://www.sciencedirect.com/ science/article/pii/S187778211 5002854 ) B12,...
