Also, do you expect the vegan alternative to have exactly the same nutritional values as their meat counterparts?
Look, I don't even know why I'm defending Beyond here, I'm certainly not a fan (as a matter of fact, I don't like their beef patties). But I think the arguments you've made are not entirely fair.
If you're salting your recipe with traditional ground beef, you're doing the same with Beyond. If not, same.
I do not expect or even encourage the content of any alternative to match the nutritional value of the real deal.
A typical pinch of salt is 300mg. Not 2300mg.
When the base product has 3x as much sodium, that is a problem. It doesn't need that much because as you stated, you can add salt during cooking. As a great example, let's take a use case for Beyond which is taco meat. I add taco seasoning (my own which is about 30% sodium compared to a traditional) and now the Beyond version is still roughly 250% the sodium content.
I can't remove the sodium they add. It's not a product I like or desire. It's more expensive. It's less healthy (note how often I mention reduced salt) for myself.
Also, I have been a strict vegan in life for about 5 years. I still didn't eat Beyond (aside from tasting it) during that period (it was available).
I'm not really trying to attack Beyond here, it's all personal preference at the end of the day. I make 95% of my food, from bread to tomato sauce to pickled peppers and hot sauce. When I am reaching for a vegan protein, I reach for lentils.
