Organ meats
When I was a kid my mom used to make fried liver with onions, lamb tongue, and kidney saute for dinner. I don't think organ meat is even sold these days.
Did you ever eat these things?
Not really a fan because I'm prone to gout and organs have high levels of purines, but its the healthiest, most nutrient dense part of the animal. I do see see them in the grocery store still, though.
shareI saw a news story once where ALPO sold a dog food made of the innards of another animal that was nutritious for dogs and which they liked. Supposedly when wild dogs kill prey they go mainly for the innards. However people wouldn’t buy it because it looked unappetizing to humans.
shareMost modern dog food is pretty shitty to be honest. Dogs aren't supposed to have a grain based diet. And you're right about wild dogs going mainly for the innards. This actually goes for most wild animals. The muscle and flesh is usually the last part they will consume.
shareI read somewhere that after thousands of years of association with humans and our diet dog digestive tracts have changed to process more vegetable material. It said that a domestic dog's gut really was different from a wolf's. Still, they're genetic carnivores and a treating them like vegetarians is probably a good way to kill them or make them really sick. Supposedly some Einsteins have actually done it. Damn. Some people are messed up!
And yeah, the organs are generally more nutritious. The fat too.
