Not once did they mention real meat in their ingredients. Both red meat and white meat have nutritional value that cannot be matched through plant proteins, and the bio-availability for your body to process and use those plant proteins is inferior to animal protein. Not to mention soy isn't that healthy in frequent servings, especially if you're a male as it raises estrogen levels. I'm a nutritionist and my statements aren't ignorant "bro". Plant proteins can be beneficial, but the function of plants in our diet isn't to serve protein needs, but other needs like vitamins, fiber, potassium, etc. This is why its bio-availability is significantly less. You can manipulate proteins into any shape you want, and that's fine. It still doesn't compare to the nutritional value of meat like protein, fat, naturally occurring creatine, essential amino acids, etc.
But I suppose if you prefer sitting on some sort of moral superiority throne behind your keyboard calling bros ignorant, then maybe it's above your standard.

They aren’t using plant proteins. They’re literally lab grown meat/animal proteins. Did you do no research? Proteins can be multiplied.
You need to read into the article instead of digesting a title.

Remember those biology classes they made you take when you trained to be a nutritionist?
I mean you do have a degree, right?
Well in those classes they probably taught you that cells grow together into organs. A chunk of 'steak' from a cow is part of a muscle organ.
So if you grew the same cells in a vat, probably in separate vats, one for each cell type - and assembled the cells into the same geometric shape as the organ - then the nutritional value will be the same.
Or slightly better - you can manipulate very easily the kind of fat the adipose cells make, right. Cows don't make enough omega-3 fatty acids but there is no reason your lab grown version has to work that way. Just edit the genes slightly so you get the fat ratio you want.
This would be better then. As a nutritionist you'd have to start putting people on a fish/lentils/lab grown beef diet.

That's an interesting theory. Not so certain that the nutritional value would be the same if it just had the same cells and same geometric shape, but I get where you're going with it. There's just something about an organ or tissues in the body that are grown and developed that we haven't nailed down yet in replicating it, but we'll get there eventually. I'm also deeply interested in genetic engineering, and hope to see the day where we could make superior meat artificially, among other leaps and bounds we could make.

So that's not how this works. You can grind up the real muscle tissue and the fake muscle tissue and assay out how much of each amino acid and how much of each lipid type is in the sample.
At this point you can modify the genes for the lab grown cells until it has the nutritional profile you want. If it exactly matches the beef steak sample, it is nutritionally the same. It doesn't matter the path taken to grow it.
