I personally don't eat red meats very much anymore due to the unhealthy factor. But the funny thing is that the vegetarian/vegan versions are probably just as processed (or even more processed) and just as unhealthy as the meat versions, and I wouldn't eat those either...
Processed?
I mean steak....it's meat cut off the animal...pretty simple, not processed much at all really.
Hell, even the sausages I make....I save all the trim off my briskets and pork shoulders I buy for my smoker and make sausage....I grind up meat and fat, and mix in some seasonings...I DO add a bit of powdered milk many times and some pink salt (nitrates) at times if I am needing to ensure I have some preservatives if needed (depends on how I'm cooking or smoking it).
So I guess that is somewhat processed, but aside from just chopping, grinding and mixing with seasonings, and stuffing in a casing, I don't consider that to be very processed at all as a sausage.
The thing being is..."I" can do this at home.
Now...to get a vegetarian version of some of these things....like vegetairn "meat"....you pretty much need a lab and chemicals and processes I cannot realistically get for home use....
I tend to eat keto leaning carnivore.....I cook mostly from scratch...and I do love veggies too, BUT...I eat my veggies in a state that starts with the real thing and doesn't take a lot of processing other than chopping or maybe pureeing in a blender....
But that's far from the prepared "veggie" foods you buy on shelves, especially the ones that try to be. Veggie "meat" or "Milk" or "cheeses".....
I don't find read meat (or chicken or pork or seafoods) to be unhealthy...in fact when I concentrate on eating largely carnivor or keto...my health seems to improve substantially.
Eating that way, I feel better, sleep better and my bloodwork numbers look good.....
I think it's the heavy commercial processed foods that need a lab are the things that are killing folks.....not a simple sausage.
A simple common sausage is just using up the scraps of meat from steaks and roasts....so as not to waste food.
