The study methodology is really flawed. They polled people on what they had for dinner "yesterday" and used that be indicative of entire diets of all Americans.
While it's likely that there are some Americans who eat far more beef than some others, this data is a farce.
I like beef ground beef for most applications, but an impossible burger is just fine at a BBQ where I'm drinking and I prefer the meat substitute for mapo tofu. Idk why, but it just works better for that dish.
