Good example of media selection bias here, notice how this study is completely ignored by mainstream media:

if it had said "Humans ate vegetables and little else" it would be on r/all now.

Don't pay too much attention to these "discoveries" being 100% true
But most importantly, you're overlooking the authors' bias. 1st/last authors seem to be making an academic career on proving that humans are carnivores. 2nd author is a self-confessed fan of low-carb diets, and listed as the founder of a company offering a nutrition tracker based on the same principles.
Not exactly an unbiased trio. And without the hinges of peer-review that would stop them from making wide claims, I would skip the news article altogether.
And not being unbiased is probably why you won't see their research on international media, that would arguably be a bit more picky, having a wider selection of science stories to choose from.
