Liver
The liver is very nutritious, and you can get over thirty-five percent of your required daily intake of iron from the liver alone. The liver is also very rich in vitamin A, and it can provide more than enough of it. Protein is another nutrient that is very present in the liver. Organ meats like liver contain a lot of B vitamins, copper, and selenium. They also include a high proportion of choline which is needed for the brain. [15, 16]
