I don't think your analogy holds water. I know the health risks of veggies, they're not that bad compared to missing them out completely. I make a conscious decision to risk it when I eat veggies, but I accept that veggies have unhealthy stuff when they're processed.

But denying a scientific fact is not the same. If people would've not just eaten veggies but called news about bad preservatives "fake news", then you would've had a point.
