That's what's stopped me from getting them. They're not any healthier (and arguably less healthy) than the meat they're substituting. I'd rather they stuck with the old soy burgers that tasted less like meat but were clearly healthier (unless you're on a keto diet) than what they've come up with.
Well sure, not the meat itself, but the nitrosamines used to cure it, that's the bad part. According to my old boss who's a cancer researcher, apparently it's pretty carcinogenic. And it's basically unavoidable, the food industry hasn't been able to come up with anything better. Not using it, and having widespread botulism is not very fun.
It turns out that most fast food burgers are made from heavily processed meat that includes various preservatives and whatnot that make it noticeably less healthy than plain hamburger, unfortunately.
