But your point is not right though! When you cook at home you put in the stuff you want to eat, that tastes good and nourishes you, and that's the point of food.
But the ingredients in highly processed foods are not there to feed you, or even to make the products tasty. They're there to accommodate the production process (eg emulsifiers), to increase the product's transportability and shelf life (preservatives), to make the product more appealing to the senses (colorings, flavorings etc) and, more worryingly, to hook you with huge amounts of salt, fats and sugar, that you don't find in base ingredients like potatoes or beans.
These added ingredients replace and crowd out the actual food you need and want to eat. That's the point, yes? The Harvard article I quoted above says it clearly: "Not all but some of these foods tend to be low in fiber and nutrients".
That's because they must be high in ingredients that are not "fiber and nutrients" and are there to improve the ability of the product to be sold, but not to nourish you. Because the primary goal of such over-processed foods is not to feed you, but to sell well.
Am I getting my point across? Whether fake meats are nutritious or healthy is not the industry's concerns. So it will not optimise for those properties. The industry's concern is to sell its stuff. So it will optimise for that. And if that ends up feeding its consumers unhealthy shit, so be it. That's the same industry that's been selling over-procssed, unhealthy, environmentally damaging junk food made of meat for years. It's now doing the same thing with plants. Nothing has changed.
