Liverwurst is a great source of protein, and it is also rich in vitamins B12 and A. It also contains iron and several other essential nutrients.
Liverwurst comes in the forms of a sausage and a spread. There are 6.4 milligrams of iron in a 3.5-ounce serving of liverwurst sausage and 4.87 milligrams in 1/4 cup of the spread. Iron aids in the production of red blood cells and prevents iron deficiency, which leads to fatigue and a weakened immune system. Liverwurst has several other important nutrients, including zinc, which keeps the immune system functioning properly, and niacin, a B vitamin that promotes nervous system health. Liverwurst is also high in saturated fat. Eating too much of it can lead to heart disease and high cholesterol, so it should be consumed in moderation.
