Calorie Breakdown of Different Types of Liver
When considering what are the calories in the liver, it is important to note that the amount varies depending on the animal source and preparation method. A raw, 100-gram serving is a standard baseline for comparison, though actual caloric intake will change once it is cooked and paired with other ingredients. For example, pan-fried liver with butter and onions will have a higher calorie count than a simmered version.
Beef Liver
Often considered the most nutrient-dense option, beef liver is relatively low in calories. A 100-gram serving of raw beef liver contains about 135 calories, alongside a significant amount of protein and crucial vitamins. This makes it an efficient fuel source, providing a substantial nutrient boost without a high caloric cost.
Chicken Liver
Chicken liver tends to be slightly lower in calories and fat than beef liver. A 100-gram serving of raw chicken liver contains approximately 119 calories. It is still a powerful source of vitamins and minerals, particularly folate and iron, making it a great option for those seeking a lighter alternative.
Lamb Liver
Lamb liver typically has a slightly higher calorie count than beef or chicken liver, but it also offers a unique nutritional profile. A 113-gram serving of uncooked lamb liver contains around 187 calories. It is an excellent source of Vitamin A and copper.
Cod Liver
Unlike other types of liver, cod liver is known for its high fat and calorie content. A 2-ounce (around 57-gram) serving of canned cod liver can contain approximately 210 calories, primarily from healthy fats. This is an exception to the rule for most organ meats, but it is prized for its omega-3 fatty acids and vitamin D content.

The Health Benefits of Nutrient-Rich Liver
Beyond just the calories in the liver, its impressive nutritional profile offers a range of health benefits that make it a worthy addition to a balanced diet.
- Prevents Anemia: The high concentration of heme iron, which is easily absorbed by the body, helps prevent iron-deficiency anemia.
- Supports Vision: The abundant vitamin A in liver is crucial for maintaining healthy eyesight and immune function.
- Boosts Energy: Liver is an exceptional source of B-vitamins, including B12, which are vital for energy metabolism and preventing fatigue.
- Enhances Brain Function: Vitamin B12 and folate, also found in high amounts, support proper brain and nervous system function.
- Builds Muscle: As a complete protein source, liver provides all the essential amino acids needed for muscle repair and growth.
- Supports Bone Health: Liver contains vitamin K, which helps the body process calcium and maintain strong bones.
Considerations and Precautions for Eating Liver
While liver is incredibly healthy, it should be consumed in moderation due to its high concentration of certain nutrients.
- Potential for Vitamin A Toxicity: The high levels of preformed vitamin A can be toxic if consumed excessively. Most experts recommend limiting intake to about once a week. Pregnant individuals should be particularly cautious and consult a doctor.
- High in Cholesterol: Liver is rich in dietary cholesterol, which some individuals, especially those with certain health conditions, may need to monitor.
- Purine Content: For those with gout, the high purine levels in liver can increase uric acid, so it is often advised to minimize or avoid it.

Conclusion: Making Informed Choices About Liver Consumption
To conclude, while addressing what are the calories in the liver provides a starting point, the conversation must expand to its rich nutritional value. Different types of liver offer varied caloric content, but all are exceptionally rich in protein, iron, and a host of vitamins and minerals. While it is a true nutrient-dense superfood, moderation is key due to its high concentration of certain vitamins and cholesterol. For most people, incorporating liver into a diet once or twice a week is a simple and effective way to boost nutrient intake and support overall health. As with any significant dietary change, it is wise to consult a healthcare professional, especially for pregnant individuals or those with specific health concerns like gout.
