LIver is highly nutritious and an excellent source of iron, so it is especially good for women of a certain age.
It is also a good source of vitamin A, zinc, copper and manganese, and a very good source of protein, vitamin D, vitamin C, riboflavin, thiamine, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, phosphorus and selenium.
I can find no evidence that it is high in cholestrol. However, because your body stores vitamin A it does not use, you should only have liver once a week or so. Over years, too much stored vitamin A can cause problems with bone fractures. As you enjoy liver, you will never need to take cod liver oil. Hurrah!
So enjoy your liver!
