What do you mean by "historically correct"?

You mean blaming sugar or meat when historically people started eating too much, in the 20th century, due to food availability?

Everything has become more abundant recently - clean water, vegetable, meat, fat, sugar, even clean water.

And less hunger too. I remember yawning repeatedly / feeling faint when I was younger but didn't know what I hungry until my mum pointed it out.

So you can't point to one or two food groups and claim their current abundance cause obesity.

Well, except white sugar lol.

id instead point to high fructose corn syrup. even more sugary than white sugar, and it's in basically all junk food instead of white sugar

Show us a reliable study comparing table sugar with HCFS that can confirm what you're saying.

You won't find any.
