At the moment I'm eating mostly muscle meat (hamburgers and sausages) and (shell)fish + organ meats weekly (liver, kidney and heart)
But since heart is muscle meat too, would it be a bad idea to replace the other muscle meat by heart alone? I know it's best to consume "the whole animal" but I'd like to hear some other arguments why I shouldn't.
EDIT: So I can conclude that eating approximately 1kg of heart per week is not bad, stand alone worse than the "normal" muscle meat?
