It's good to eat sans salt on bbq with your desired (typically salty) toppings.
I know people salt the patty while cooking, but the topic at hand is Beyond and their patties.
The whole "salt" angle is bikeshedding - no one advocated Beyond for salt, they pick it for all of the other health benefits (fats, cholesterol)
Nothing whatsoever is stopping Beyond from removing salt and allowing people to salt their own burgers, as they already do.
I'm on blood pressure meds. I regularly check in with doctors on things. No, you shouldn't be eating unlimited salt, but sugar and cholesterol are killing (and debilitating) many more of us.
What matters is not so much the natural form, it is how the product is typically consumed.
But of course I see your point that with home made meat-based patties, you are in control of how much salt you want to add, while with factory made patties, you have to take what you get, it's typically not possible to "take away" salt. Mind you, though, the latter argument holds for both plant-based and meat-based factory-made patties.
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.
