What's your concern about the nutritional content of Beyond Meat? Its macros are comparable to that of the product it replaces.
We got used to vegetarian = healthy because for a while it meant grain, veggies and fruits. But today half of the vegetarian/vegan processed food is as bad as regular processed food.
I'll take an halloumi/spinach patty burger over a beyond meat burger every day
If all that mattered in nutrition were prots, fats, carbs and sodium it would be muuuuuuch easier but sadly it's infinitely more complex than that.
