The "lab-grown" term is [EDIT: sometimes and apparently incorrectly] used for plant-based meat substitutes like Impossible Burger. It probably shouldn't be, but it is.
I honestly don’t think there can be any argument there. Plant-based meat substitutes have been around for a long time, are emphatically not “lab grown meat”, and I have never heard anybody refer to them as such. That’s a distinct category which has also been receiving a lot of attention in the past few years.
I, too, used to confuse Memphis Meats with Impossible Food / Beyond Meat.
It's just that news of lab-grown meat and outfits like Impossible Food kinda sprung up at the same time in the news within the last 5 years and it's easy to confuse the endeavors. In fact, I see this misconception enough that I think IF/BM benefit from the confusion.
I have never heard anyone so confused that they can't tell the difference between "animal that was never alive" and "made from vegetable products". This isn't confusing, and I will need evidence to believe that it is "widely used". I don't think I've ever even heard someone attempt to conflate the two before you.
But I acknowledge that just because this is completely obvious to me and I've never met someone who was confused about the difference doesn't mean they don't exist.
I honestly don't care what people call the different types of meat substitutes. Plant-based meat seems a bit odd to me because it's not, you know, meat. But it seems to be the term in use.
Yes, I understand that there is a difference between grown from meat cells and made from plants with components that make it look and taste more like meat.
102,000 of those are "plant-based meat alternatives". 46,700 are for "plant-based meat substitutes". I'd imagine there are quite a few other synonyms that continue to winnow it down.
