Your exactly correct, it is high in dietary cholesterol, but most folks don't have a steady diet of it, so it's not a big issue apparently.Liver is supposedly very high in cholesterol. A cardiologist once said 1 serving was equal to eating a dozen eggs in one sitting. I never liked liver as a kid, mom didnt know to soak it in milk so it tasted really strong. I recently tried it again after soaking it and it was really good.
The health benefits of eating liver is pretty substantial.
Too long to post the text, but this link gives the pluses and minuses.
