It's an open secret things like "Impossible Meat" and others are really not healthy for you - certainly not a healthier alternative than just eating beef. They are higher in calories, and contain a lot more oils.
Instead, it's for people who wish not to eat meat for whatever reasons (personal choice, religion, etc)... and now they can have a tasty alternative at the next Backyard BBQ.
I'm not against meat but I do view 'vegetarian strategic path to meat elimination' as entirely economic.
People care more about their money than anything that's how it will happen in my view.
That said - if it tasted 'really good' I don't mind at all now and again personally and I feel probably most people feel that way as well. If I had burgers once every two weeks and 1/3 of them were 'good vegan' I would fall into just considering it 'another choice in the menu' type of thing, which I believe a lot of folks will go for.
This already exists. Tofu is commonly used in fast food as a meat "filler", and very few people notice as it is. Tacos at Jack in the Box "May Contain Soy Products", and more.
Making "Impossible Meat" is always going to be more expensive than Tofu fillers, simply because it's processed to a much higher degree and requires a lot of ingredients.
But yeah the macro-nutrient composition of this meat substitute patties is as unhealthy as meat as they are very high in fat. The sodium content is also really high so they don't help with high blood pressure issues.
