Diet Ratings
Pork liver contains approximately 3-4g net carbs per 100g, higher than muscle meat due to glycogen storage. Nutrient-dense (iron, B vitamins, choline) but requires portion control. Small servings (2-3 oz) fit within daily carb limits.
Strict clinical keto protocols limit organ meats due to carb content; most mainstream keto practitioners include moderate portions as nutrient-dense foods.
Pork liver is an animal organ from slaughtered pigs. It is explicitly excluded from all vegan diets.
Pork liver is an unprocessed organ meat, one of the most nutrient-dense foods available. Organ meats are paleo staples, rich in vitamins A, B12, iron, and folate. Nose-to-tail eating.
Pork liver is a pork product (red meat). Mediterranean diet limits red meat and pork to a few times per month. While organ meats have some nutritional value, pork is not the preferred protein source. Fish and poultry are strongly preferred over pork.
Organ meat from pork with exceptional micronutrient density (vitamin A, B vitamins, iron, copper, selenium). Carnivore practitioners highly prioritize organ meats for nutritional completeness.
Pork liver is a whole, unprocessed organ meat. Whole30 explicitly allows all meat and organ meats. This is a fully compliant, nutrient-dense protein source.
Pork liver is a protein-rich organ meat with minimal carbohydrate content. Monash classifies all unprocessed meat and organ products, including liver, as low-FODMAP. No FODMAPs are present in this food.
Pork liver is nutrient-dense (iron, B vitamins, folate) but high in cholesterol and saturated fat. DASH limits red meat and high-cholesterol foods. Portion control and lean preparation are essential. Chicken or fish liver are preferable alternatives.
Some DASH practitioners accept organ meats like liver as nutrient-dense protein sources in small portions (2-3 oz), whereas traditional DASH guidelines recommend limiting red meat and high-cholesterol animal products.
Pork liver is a nutrient-dense protein source (~26g protein per 100g) rich in iron, B vitamins, and polyphenols. However, it contains higher saturated fat (~5g per 100g) and cholesterol. Zone-compatible as a protein block but requires careful portioning and should be balanced with monounsaturated fats.
Pork liver is nutrient-dense with iron, B vitamins, choline, and selenium—all beneficial. However, it is a red meat organ high in arachidonic acid and cholesterol, which can promote inflammatory pathways. Acceptable occasionally as part of a varied diet but should not be a primary protein source in an anti-inflammatory framework.
Nutrient-density advocates view organ meats as superfoods for micronutrient status. Anti-inflammatory frameworks prioritize plant-based and fish proteins, making liver a secondary choice despite its nutrient profile. Some paleo and ancestral diet advocates rate liver more favorably.
Pork liver is very high in protein (~26g per 100g) and micronutrients (iron, B12, folate) but also high in saturated fat (~5-7g per 100g) and cholesterol. Nutrient-dense but fat content may trigger GLP-1 side effects. Acceptable in small portions (2-3 oz) paired with high-fiber vegetables; not ideal as a frequent primary protein.
Some GLP-1 clinicians recommend organ meats as superior micronutrient sources despite fat content, while others prioritize lean proteins (chicken breast, fish) to minimize GI side effects and saturated fat intake during rapid weight loss.
Nutritional profile
