Whether it's any healthier doesn't really matter to me. I'm excited to be able to enjoy bacon without paying for the inefficiency of raising animals.
Just the spore costs to produce a lb of mushrooms can rival the total cost to raise a lb of pork (commercial pork can be as cheap as $64/CWT carcass weight - so $0.64/lb. Mushroom spore can be as high as $1.00 in spore costs to generate 1lb of mushroom). Processing the meat will raise costs, but it's hardly like mushrooms have low care/processing costs (If you don't know, they often require clean room levels of care to ensure proper spores without contamination).
There's a reason white mushrooms (unsliced) goes for $4.49/lb at my local Kroger, and the boneless pork goes for $1.99/lb.
I don't see this ever being cheaper.
I'm not at all convinced a pound of mushrooms is worth that much more than pork. Are you sure it's not the meat industry subsidies that are keeping the price down?
The problem mushrooms have is scale, much like spices. We can grow 20K acres of mechanized corn, but mushrooms are a little less mechanized. So its to be expected for mushrooms to cost as much as basil or cilantro per pound.
It's mostly speculation, imho, as people are willing to spend more on these products. Some of these things are just as bad, if not worse, than cheap real meat. Back in the before going full veggies, I've tasted some horrible things that should be illegal. I am baffled people are willing to eat factory chicken, pork, etc. Shit is disgusting even if you don't care about the horrible lives of all the animals
If the product is not meat, shouldn't be tagged as meat.
