Pig liver and sheep liver, which is more nutritious and safer, can be compared from the following aspects:

Main nutritional components: in terms of energy and fat content, sheep liver has the highest energy; Among protein, the protein content of pig liver is the highest; Let's talk about vitamin A first. It is a very important vitamin in the liver, and the eyesight improving effect of the liver is attributed to it. Vitamin A can also promote growth and development, maintain skin health and enhance immunity. The content of sheep liver is the highest, followed by pig liver.

Cholesterol content: sheep liver has the most cholesterol, while pig liver has a little less.

Mineral content: pig liver is rich in iron and other minerals such as zinc, with high digestion and absorption rate. Therefore, anemia patients, pregnant women and children can choose pig liver.

Safety: Because the liver is the largest detoxification organ in animals, it is easy to accumulate toxins, so eating the liver should consider safety. Generally speaking, the growth period of large animals such as cattle and sheep is long, so there are more toxins accumulated in the liver, especially in cattle liver. In addition, large-scale cultured animals that are prone to illness should also eat less liver, such as chickens. So relatively speaking, duck liver and pig liver are slightly safer.

So in general, you can't evaluate which is better, but you can choose according to which aspect of your liver you care about.
