That you will try and educate yourself in the nuances of a complicated topic like nutrition and wont advocate for anti intellectual and anti scientific shorthand doomerism that makes people less educated and capable of distinguishing healthy habits?

> We've been eating veggies and fruits for hundred millions of years without any problem but 4 decades of processed food skyrocketed all of our lifestyle related health issues.

None of this is true. We have been dying of starvation, food borne illnesses and nutricional deficits for millenia, industrilisation and post war economies have replaced that with hyper caloric ultra processed food that hand in hand with more sedentary lifestyles have skyrocketed a limited amount of health issues like cardiovascular problems.

We dont die of iodine deficiencies because we added it to salt, we dont die of scurvy because citric acid is common and citrus fruits plentiful, varied diets and better agriculture means locusts, bad weather, insects and specific harvest destroying pathogens happen less often and dont kill all our crops.

Btw in our modern world places like italy, the basque country, japan still have incredibly healthy populations. They mostly eat veggies, fish, fatty oils and walk alot. Their portions are also smaller than in places like america. And its not like ultra processed food doesnt exist there, or that they dont use chemicals in their food production.
