There's also a limit between a healthy lifestyle and enjoyment of life, beyond which towards "maximum health" you'll either go to an early grave because of how bland your life is, or live a joyless life avoiding things you'd enjoy.
In any case, those kind of "research" is for modern americans (and people taking their cues from anglosaxon culture) , who are already conditioned in such hysteria - which is funny in the country eating some of the worst quality food in the Western world, cooked the worst ways, in the worst portions, and with the worst mass production integredients. Or perhaps an overcorrection.
The average Italian, for example, should, and definitely, would just laught this off.
