A few tiny shakes out of a salt shaker isn't going to come close to 90mg. Figure about 40mg because I use a very small amount of it when I do use it. I'd have to eat 9 of mine to get the same salt content as a plant burger sold here.
But wait, there's more! National brands of everything here load their products up with salt. Buns, condiments, fries, drinks are all packed with sodium. Under the guise of eating healthy, one can eat a loaded up plant burger w/fries and a cola and consume a day' worth of salt in one sitting.
370mg of salt in a single patty is an absurd amount of salt.
Does the cooking itself add sodium? Salting isn't mandatory, and there are tons of spices you can add if you want some extra taste that aren't salt (i know this might be anathema to some who think seasoning starts and stops with salt and maybe pepper but it's true, try it out!).
I expect people salt their impossible burgers too.
I think it’s accurate and fair to list the direct ingredients rather than estimating what the nutrition content is after cooking. That gets pretty hard to follow as cooking varies substantially.
For example, I might bake my broccoli with olive oil. Does that make it misleading to only show the fat content of broccoli and not the olive oil?
While I agree with your comment, this is very misleading unless you eat your steak raw and unsalted.
