Plant-based meat soon with animal fat? That's behind the plans. Some companies are growing fat in the lab and hoping to combine it with wheat protein and spices to create a particularly meaty form of plant-based bacon.

The shift could change the identity of plant based meat, which has previously been seen primarily as an option for vegans and vegetarians. But advocates see it as something special: a tasty way to bring plant- based meat away from the small share of consumers who don't eat meat and into the mainstream.
