Not an edible product, but an eating product.
The shirt I'm wearing right now is 100% cotton and perfectly edible.
Probably more edible than a lot of processed food products on offer at the local Safeway.
The problem with labeling that fake food as "food" products is that it maintains the fiction that this stuff is somehow related to that nutritious stuff formerly known as food, but now engineered to titillate the taste buds and fill the belly.
These aren't food products.
They're eating products.
