A Look at the Macronutrient Profile
Beef lungs are distinguished by their balanced macronutrient profile, offering a high-protein, low-fat option among organ meats. This makes them an excellent choice for individuals focused on lean protein sources without excess caloric intake. For every 100g of cooked beef lungs, you can expect a substantial amount of protein, which is crucial for muscle repair, growth, and overall cellular function. The fat content is relatively low, and for grass-fed varieties, a higher proportion of healthy polyunsaturated fats may be present.
Protein and Fat Content in Cooked Beef Lungs (per 100g):
- Protein: Approx. 20.4 grams
- Fat: Approx. 3.7 grams
- Carbohydrates: 0 grams
Rich Source of Essential Micronutrients
Beyond its strong protein content, what is the nutritional value of beef lungs when it comes to vitamins and minerals? This offal is a micronutrient powerhouse, providing several key vitamins and minerals that support numerous bodily functions.
Important Vitamins
- Vitamin B12: A 100g serving of cooked beef lungs can provide a significant portion of your daily recommended intake for Vitamin B12, which is vital for nerve function, DNA synthesis, and red blood cell production.
- Vitamin C: Unlike many other beef products, lungs contain a notable amount of Vitamin C, a powerful antioxidant that helps protect cells from damage.
- Other B Vitamins: Lungs are also a good source of Niacin (B3) and Riboflavin (B2), which are essential for converting food into energy and for maintaining healthy skin and nerves.
Crucial Minerals
- Iron: Beef lungs are particularly rich in highly-absorbable heme iron, which is necessary for creating hemoglobin and carrying oxygen throughout the body.
- Selenium: This trace mineral is essential for proper thyroid function, reproductive health, and provides antioxidant support.
- Zinc: An important mineral for immune function, protein synthesis, and wound healing, beef lungs provide a valuable source of zinc.
- Phosphorus: Lungs contain phosphorus, which plays a critical role in building strong bones and teeth, filtering waste in the kidneys, and managing the body's energy stores.
Beef Lungs vs. Beef Liver: A Nutrient Comparison
While beef liver is often hailed as the king of organ meats, beef lungs offer their own distinct nutritional profile. The following table compares key nutrients per 100g serving (cooked, braised):
| Nutrient | Beef Lungs (Cooked, per 100g) | Beef Liver (Cooked, per 100g) | Notes | 
|---|---|---|---|
| Calories | ~120 kcal | ~191 kcal | Lungs are lower in calories | 
| Protein | ~20.4 g | ~29.1 g | Liver has higher protein content | 
| Fat | ~3.7 g | ~6.4 g | Lungs are considerably leaner | 
| Vitamin B12 | ~2.6 mcg | ~59.3 mcg | Liver is exceptionally high in B12 | 
| Iron | ~5.4 mg | ~7.2 mg | Liver has slightly more iron | 
| Vitamin C | ~33 mg | ~1 mg | Lungs are much higher in Vitamin C | 
Practical Preparation and Usage
Due to its unique spongy texture, beef lung requires specific preparation methods to become tender and palatable. It is often slow-cooked or braised to soften its texture. Some chefs recommend not washing the raw lungs, as they can absorb water and become soggy.
Cooking Preparation Steps
- Slice: Cut the organ meat into bite-sized cubes or strips.
- Sauté: Sauté the meat in oil with bay leaves and spices until browned to create a flavorful base.
- Braise: Add liquids like stock or tomato paste and water, then cook on low heat until the lungs are tender.
Beef lungs are also a popular single-ingredient dog treat, sold dehydrated and in bite-sized pieces. For humans, it can be incorporated into stews, pâtés, sausages, or braised dishes, where its mild flavor absorbs other seasonings well.

Conclusion
What is the nutritional value of beef lungs? It is a nutrient-dense and affordable food source, rich in high-quality protein, essential B vitamins, iron, and selenium. While not as concentrated in all nutrients as liver, it offers distinct advantages, particularly its high Vitamin C content and lower fat profile. By utilizing proper cooking techniques, beef lungs can be a flavorful and valuable addition to a balanced diet, offering a cost-effective way to boost micronutrient intake.
