This has no bearing on the argument. That is just as true of vegans who purchase boxed products.
It's also fairly US-centric. If you observe countries with the longest lifespan, lowest CVD incidence and overall best health outcomes, they consume a more varied whole-foods diet with animal products.
> the classic diet
This is the Americanized diet of ultra-processed foods. Whole foods are the solution, which is in no way shape or form contingent on whether animal products are included (unless the diet is "carnivore" which is not representative, and even there you can find traditional societies who fare ok even if not completely optimally).
I agree that a whole food diet is better than the “boxed” one but I have no comparaison point for the US. I’m from France and many people value whole food, “good products” and cook at home however even those gets diabetes, intestinal and blood cancers and other problems that would be easily avoided with more vegetable consumption. The fact is meat is often the central peace of the dish, second the carbs and then salads, cabbages and roots. People say they loves them but when they are on the plate it’s more a decoration that a portion.
