if we know any studies

No, obviously not since these are absolutely new products. Supermeat (Israel) is even not yet licensed.

As such it would be difficult to have objective studies since the researchers couldn't yet purchase the product and would have to rely on the manufacturer or the manufacturer would even have to commission the study.

I'm pretty sure tho that, unless you're a health nut, there's plenty of studies highlighting how bad a lot of the food you currently eat is. :3
