Earlier quoted context omitted.
People say that, but when the Academy of nutritionist and dietetics and various government agencies says it is possible to live a healthy life on a plant based diet you know it is baloney. It consists mostly of the things people have been telling us to eat for ages. Whole grains. Legumes. Leafy greens. Vegetables. Some vegetable oil like rapeseed or olive oil. Supplement with b12 and drink fortified milk alternatives…
"ages" = a few decades tops "you know it is baloney" -> I do not "but when the Academy of nutritionist and dietetics and various government agencies says" LOL I will refrain from commenting on such topics in the future, the ideological grip on some is hopeless for the time being.
Before that people are traditional food, which usually was quite healthy if you had at least some economic means (otherwise it was a lot of rye, fish and potatoes in Sweden).
With the economic growth after the war people started deviating from healthy dietary patterns, which is why nutrition recommendations start popping up from the late 50s.
Who are we supposed to trust with nutrition if not the people that actually work with understanding the science? I do know that the USDA have quite a lot of industry influence, but that is not the case everywhere.
Most dietary recommendations look like the Mediterranean diet, which we know have very good health outcomes, with local adaptions. For a good reason.
