Hi, I'm a biotech major and a scientist. This meat is made by using large vats of cultured cells. Specifically, muscle fiber cells. To get the same nutritional value as real meat you would need to have each type of cell usually present in an animal muscle. Which is difficult to even know, let alone develop, grow (some cells are harder to grow than others) and structure into a muscle replacement.

I don't like OPs naturalistic bs. Proteins are the same if synthesized or cut out of the cow. But this slab of printed mush is not nutritionally equivalent to real meat. Proteins aren't the only thing you require from meat. It's in fact the least important thing on it. You can get protein from plants too, you can't get, however, several important vitamins, iron, carnitine and fatty acids that are simply not produced by muscle cells alone.

And if we do ever make such a real replicas it will be incredibly taxing for the environment.

The Amazon will have to burn down at twice the rate.
