Sweeteners are about 15% of calories for Americans which sort of undercuts your idea that it’s all about corn syrup. Your example of a single hypothetical meal is irrelevant - the data is clear that Americans are practically vegetarian, in aggregate. 70% plants is absolutely “practically vegetarian” compared to, say, a diet consistent with the pre-agricultural evolutionary environment of most Americans. Personally, in excess of 90% of my caloric intake comes from animals (and I am visibly and medically healthier than 95% of Americans, even health-focused herbivores, as are people I know who eat similarly).

Preindustrial diets where mostly plant based in aggregate. Even if you look before agriculture estimates place typical hunter gatherers at about 65% plant based with extreme variation. Which is the same ratio as Americans eat when you exclude those sweeteners. Longer term surviving examples tended to have a higher meat based ratio largely because they lived on islands or in more marginal areas. However, looking at land area and population density estimates adjusts the ratio significantly. Some of this needs to be inferred from things like Native American tribal densities and is further confused as diseases decimated native populations throwing off those density estimates. Still the idea of our ancestors eating a primarily meat based diet seems to be a mistake.

    Several issues with that statement, we largely didn’t have snow bound ancestors largely because survival was significantly more difficult in cold areas. Historic populations also tended to lose a lot of weight in winters due to lack of food. On top of this mercator projections seriously distort people perceptions of how much land is near the equator vs the north. Africa is 11.73 million square miles with minimal snowfall outside of a few mountains, Europe is 3.9 million square miles. Combine that with warmer areas providing more food and it’s likely the majority of early modern humans never experienced significant snowfall. This is complicated by ice ages, but people didn’t spend a lot of time on on near glaciers until very recently. Lack of food and warmth where huge issue before relatively advanced though still Stone Age technology. Another way of thinking about this is to compare animal biomass per square mile in say Mongolia with Ghana.
