Why rice and beans specifically, out of all foods? So a piece of advice I see often, both in communities that promote eating less meat due to ethical reasons, and here for financial reasons, is to eat a lot of rice and (dry) beans. And like... Is there a specific reason why this combo? I'm aware beans are pretty high in protein for plants, but why them specifically? Is it some kind of aminoacid or vitamin-related reason? Or just regional differences in price and availability? I ain't in the USA, so beans actually aren't that cheap - they tend to be 12 zł/kg off-sale here, while dry peas, which have around the same amount of calories and protein as beans, are 4zł/kg. Cheapest off-sale boneless pork is probably the same as beans, 12zł/kg, but it goes on sale more often, and goes down to 8zł/kg or even 7zł/kg regularly. Chicken liver tends to be around 7zł/kg even off-sale. I understand that meat is less "bulkable" than dry plants, but still Similarly, why rice?…
