> “Fallacious arguments abound for the carnivore group all the way over to the militant vegans who would want to tax or outlaw meat eating altogether, while telling us to shut up and eat our processed patty of canola oil and isolated pea protein. For now, I’ll keep eating like my grandparents ate - you know, real food.”
It sounds to me like just more bullshit food nostalgia nonsense and you’re just perpetuating your own brand of unscientific nutrition opinion. Researching that a bunch of other hypotheses are wrong or partially wrong doesn’t mean your idea is right.
“Eating like my grandparents ate” for a lot of people in the US means a wildly lopsided diet of mostly meat and a slew of convenience foods foisted on consumers during the advent of mega supply chain processed foods. “Eating like my great grandparents ate” usually means “eat whatever you can and don’t complain” with no serious regard for nutrition or balance.
There are likely confounding effects in rate of disease, obesity, early death etc. due much more to lifestyle differences, general sources of pollution, sedentary habits, prevalence of jobs requiring hard physical work (where even the same job in the same company today is likely partly automated or handled differently to reduce physical labor), lack of good medical screening or testing in past generations obfuscating knowing true rates of disease or health problems due to diet back then, different structures for ensuring screening in schools, etc. The sheer volume of confounding effects that would have to be convincingly controlled for to compare causal impact of past generations’ diets is staggering. If we can’t even get good science on simple studies across cohorts today, it seems like a ludicrous stretch to claim universal positive causal effect from eating “like my grandparents ate.”
The tone of your last paragraph also makes it sound like you would not give credence to ideas of choosing food options that reduce water depletion or CO2 emissions, or even the philosophy of just animal welfare and cruelty in even small-time farming (not saying we know with great certainty what those choices or green impacts would be, only that you seem to have made up your mind that some Norman Rockwell Americana picture of green beans and chicken on the table represents The Right Choice).
If you don’t actually feel that way, you may want to consider writing more charitably and not invoking food nostalgia as the alternative to flawed modern nutrition science.
