What are some of the less popular or unusual organs out there to try other than the well known brain, liver, kidneys, marrow and tongue?
I'm interested in those that we only very rarely hear about, yet would be a regular part of a traditional diet.
Also, bonus points if you can pin point some nutrients that are found in higher amounts only in specific organs and that would have helped caveman obtain his nutrition.
For example, I've read about people reporting mild vitamin C deficiencies on a long term very low carb diet, and it's true that vitamin C is scarce in animal products, but the thymus gland is actually pretty high in vitamin C.
Any others like that? Could we get our iodine by eating thyroid glands? More testosterone by eating testes?
I think offal should rhyme with a lot more than just liver and marrow, yet it seems to be getting harder and harder to get all the organs because of regulations.
