Which offal should I eat, to maximize nutrition? Currently I eat lambs faces (lots of fat at the back, tongues and the eyes), hearts, liver and blood. I make soups with very marrowy bones, and eat the marrow when it's easy to get at. I don't particularily care for kidneys, though if they are nutritous and should be eaten, I could mix them with other meats.
Is there anything I'm missing? What about brains? Aren't they too risky? I've heard that the thyroid is very good for you and was a prize among hunters. Is it possible to get thyroids at all? What about other glands, like the pancreas? Is there any offal that one shouldn't eat? I've heard that the liver may be too rich in vitamin A and should only be eaten in great moderation. Is that something that rings true?
