The Composition of Animal Fats: Pork vs. Chicken
When comparing pork fat (rendered into lard) and chicken fat (rendered into schmaltz), their nutritional profiles differ significantly, primarily in the types of fatty acids they contain. While both are sources of animal fat, chicken fat is generally characterized by a more favorable balance of unsaturated fats.
A Breakdown of Fatty Acids
- Saturated Fat: A key distinction lies in saturated fat content. Per 100 grams, chicken fat contains approximately 29.8g of saturated fat, whereas lard contains a notably higher amount at 39.2g. While a 2025 source found a smaller difference in saturated fat for 3oz servings (3.1g in chicken vs. 4.1g in pork), the overall trend holds that pork fat is more saturated. The American Heart Association states that red meat, including pork, generally has more saturated fat than skinless poultry.
- Monounsaturated and Polyunsaturated Fat: Chicken fat generally has a higher percentage of beneficial monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). A 2006 comparison found that 100g of chicken fat has 44.7g MUFAs and 20.9g PUFAs, while lard has similar MUFAs (45.1g) but significantly less PUFAs (11.2g). MUFAs are associated with lower blood cholesterol levels.
- Omega Fatty Acids: The omega-6 to omega-3 ratio is a modern concern, and for conventionally raised animals, both pork and chicken can be high in omega-6 fatty acids due to grain-based feed. Pasture-raised animals or those given omega-3-enriched feed can have more balanced omega profiles.
Cholesterol and Heart Health
While some older studies presented mixed data on which fat contained more cholesterol, more recent nutritional information shows minimal differences between lean cuts of pork and chicken. For instance, a 3oz serving of skinless chicken breast has 80mg of cholesterol, while a lean pork chop has 75mg. However, the most significant impact on blood cholesterol comes not from dietary cholesterol itself, but from the saturated and trans fats consumed. A 2025 study highlighted that diets rich in animal fat with high saturated fatty acids, particularly milk fat, led to higher LDL (bad) cholesterol compared to diets supplemented with chicken fat or olive oil. This suggests the overall fatty acid composition is more important for heart health than the small differences in cholesterol content.
The Importance of the Cut: Fat is Not Universal
It's crucial to distinguish between the fat rendered from an animal and the fat found in a specific cut of meat. Lean pork cuts, such as pork tenderloin, can be just as healthy as skinless chicken breast. The key is trimming visible fat and removing the skin from poultry to reduce saturated fat intake significantly. For example, a roasted pork tenderloin has the same amount of saturated fat as a roasted skinless chicken breast. Focusing on lean, unprocessed cuts of both poultry and red meat is a recommendation from health organizations like the American Heart Association.
How to Use Pork and Chicken Fat in Cooking
Both lard and schmaltz are excellent cooking fats with high smoke points, meaning they can be used for high-heat cooking without breaking down into dangerous components as easily as some vegetable oils.
- Schmaltz is excellent for sautéing onions, frying potatoes or eggs, and adding rich flavor.
- Lard, particularly high-quality leaf lard, is prized in baking for creating flaky pastry crusts.
Moderation is always key regardless of the fat source. Using these fats in smaller quantities for flavor, rather than as a primary cooking medium, is a balanced approach.
Comparison of Pork Fat (Lard) and Chicken Fat (Schmaltz)
| Nutritional Aspect | Rendered Pork Fat (Lard) | Rendered Chicken Fat (Schmaltz) |
|---|---|---|
| Saturated Fat (per 100g) | Higher (approx. 39.2g) | Lower (approx. 29.8g) |
| Monounsaturated Fat (per 100g) | Comparable (approx. 45.1g) | Comparable (approx. 44.7g) |
| Polyunsaturated Fat (per 100g) | Lower (approx. 11.2g) | Higher (approx. 20.9g) |
| Omega-6/Omega-3 Ratio | Often high in grain-fed pigs | Often high in grain-fed chickens |
| Overall Fat Balance | More saturated than chicken fat | More unsaturated than pork fat |
| Potential Health Impact | Higher saturated fat could raise LDL cholesterol | More favorable profile due to higher unsaturated fats |
| Best Culinary Use | Baking (flaky crusts), frying | Frying, sautéing, adding flavor |
Conclusion
While the specific cut and cooking method are paramount, a pure nutritional comparison shows that chicken fat (schmaltz) generally has a more favorable fatty acid profile than pork fat (lard). Its higher percentage of beneficial unsaturated fats, particularly polyunsaturated fats, is a key difference. However, calling one fat definitively "worse" is an oversimplification. Lean cuts of pork, when trimmed of visible fat, can be an equally healthy protein source compared to skinless chicken. For optimal health, focus on incorporating lean, unprocessed cuts of meat and practicing moderation with rendered animal fats, regardless of their source.
