Liver is good, and nutritious...
It's cheap because people hated it as kids, and if people start eating it, it'll stop being cheap.
Like, livers don't grow on trees. It's not like we can increase production of just that. Telling everyone to eat liver cuz it's cheap, just makes it more expensive.
The real answer is just less meat, but RFK can't say that because he's telling people most of their calories should come from meat and animal fats.
