Nutrition, being a basic of human survival, has been sovled for millenias. We just lost it with pushing industrialized food production, of any kid, way to far over the point needed to get rid of starvation.
Humans were mostly subsistence cultures for millennia (which means a period of a thousand years, so you are saying we solved this thousands of years ago). We routinely starved to death and only recently figured out something called "nutrients" exist in food. It isn't that long ago we discovered Vitamin C as the cure for scurvy and it's the reason we have nicknames like "limeys."

That's from the 1850s. Not from two thousand years ago.
>Beriberi was a serious problem in the Japanese navy: Sailors fell ill an average of four times a year in the period 1878 to 1881, and 35% were cases of beriberi.
It was caused by a vitamin B1 deficiency. Sailors were eating mainly white rice (polished) rather than brown rice (unpolished) while underway. A more varied diet eventually fixed the problem.
We have barely scratched the surface on the topic of nutrition and disease.
What really got me to accept that maybe animal products might be detrimental is Dr. Gregor talking about the exogenous endotoxin theory. Dead bacteria in your food, no matter how or how long you cook it, will produce an inflammatory response. Animal fat may assist these endotoxins due to the structure of the gut wall.[0]
When it was put into these terms, it makes it way more apparent. The plan is to reduce consumption of animal products and when I do want to eat meat, get it from a high quality source with a lower endotoxin load.

Anecdotally, over the last four years I went from eating pre-packaged ready meals every day to knowing my local butcher and cooking properly, and I feel a thousand times better than I used to.
People ask what future generations will cringe about from our lives today and prepackaged foods, ready meals, and fast-food will be my pick. Zapping a plastic container in a microwave for 3 minutes cannot be good for the food, the container or human eating it.
Finding out what crap is, is really really hard if you want to be scientific. It may be possible for some bigger categories.
Reducing is also really, really hard.
Nutrition hasn't been solved for millenia, humans just ate what they could eat, if they had enough.
Got it.
