A couple thoughts: - If you don't have cancer and stop eating, you'll likely die of starvation before you get cancer. - California made a law that says you have to label products if they contain stuff that might cause cancer. As a result, every product that might ever get sold in California has a label that says "This thing might cause cancer". It's safer to have the label just in case. Otherwise you'd have to check every cancer claim anyone publishes anywhere against all the inputs everywhere along your supply chain, recursively all the way back to farms and mines. Can you say with confidence that if some guy at the University of Boondocks publishes an article in the Timbuktu Journal of Basket-Weaving saying X might cause cancer, you'll see it? Can you say with confidence that even if you do, you'll always know if your supplier's supplier's supplier is using X? Easier to just say "We can't be bothered, just slap a cancer warning on everything we make so our liability goes away" and be done with it. For those reasons, I would say the claim "Everything we eat is associated with cancer" is true, but not useful.
