The Core Macronutrients: Protein, Fat, and Calories
When evaluating any protein source, the core macronutrients—protein, fat, and total calories—are the first factors to consider. A 100-gram serving of cooked lean chicken breast is often compared with a similar serving of lean pork, such as pork tenderloin. Both are high in complete, high-quality protein, providing all nine essential amino acids needed for muscle growth and repair. However, some subtle differences exist depending on the specific cut.
For instance, lean cooked pork tenderloin can have a similar protein density to skinless chicken breast, sometimes even offering slightly more protein per calorie. The total fat content varies more significantly. Skinless chicken breast is famously low in fat, while even lean pork contains a slightly higher fat content, with a different fatty acid profile. Pork has more monounsaturated and saturated fat, whereas chicken has more polyunsaturated fatty acids. When comparing cuts beyond the leanest options, such as chicken thighs versus fattier pork cuts, the caloric and fat differences become much more pronounced.
A Deeper Look at Vitamins and Minerals
Beyond the macronutrients, the micronutrient profile is where the two meats show the most notable distinctions. Pork is often praised for being a rich source of B-vitamins, containing significantly higher levels of certain types than chicken.
Pork's Powerhouse Vitamins
- Thiamine (B1): Pork is an outstanding source of thiamine, essential for energy metabolism and nerve function.
- Vitamin B12: Found almost exclusively in animal products, B12 is vital for blood formation and brain health.
- Vitamin B6: A key player in red blood cell formation and protein metabolism.
- Vitamin D: Unlike chicken, pork can contain some naturally occurring Vitamin D.
Chicken's Key Micronutrients
While pork may lead in some areas, chicken is not without its own strengths. It is a very good source of niacin (B3), which helps with energy production, and phosphorus, crucial for bone health. Chicken also provides a decent amount of selenium, an important mineral for thyroid function.
Pork vs. Chicken: Side-by-Side Nutritional Snapshot
This table illustrates the general nutritional differences between cooked lean pork tenderloin and skinless chicken breast per 100g serving:
| Nutrient | Lean Pork Tenderloin | Skinless Chicken Breast |
|---|---|---|
| Calories | ~143 kcal | ~165 kcal |
| Protein | ~26g | ~31g |
| Total Fat | ~3.5g | ~3.6g |
| Saturated Fat | ~1.2g | ~1.0g |
| Cholesterol | ~75mg | ~80mg |
| Thiamine (B1) | High | Low |
| Vitamin B12 | High | Medium |
| Niacin (B3) | Medium | High |
| Iron | Higher (Heme) | Lower (Heme) |
| Zinc | Higher | Lower |
Health Considerations Beyond the Plate
Choosing between pork and chicken involves more than just a nutritional label. As a red meat, fresh pork has historically carried different health associations than white meat like chicken. Studies have shown that substituting red meat with poultry may reduce the risk of certain health issues, such as type 2 diabetes and some cancers. However, these studies often focus on processed red meats and consumption patterns rather than fresh, lean cuts. For example, the way the meat is cooked has a significant impact. Cooking at very high temperatures, like grilling or frying, can produce carcinogenic substances, a risk associated with both pork and chicken.
The Role of Variety and Preparation
Ultimately, a balanced diet should incorporate a variety of protein sources to ensure a wide spectrum of nutrients. For individuals focused on minimizing saturated fat, skinless chicken breast remains a very lean option. However, for those looking to increase their intake of key nutrients like thiamine, zinc, and B12, incorporating lean pork tenderloin is an excellent strategy. Cooking methods matter immensely, and opting for baking, poaching, or stir-frying over deep-frying or char-grilling will always be the healthier choice for either protein source.

Conclusion: More Alike Than You Think
When assessing whether is pork as nutritious as chicken, the answer is far from a simple yes or no. For very lean, unprocessed cuts like pork tenderloin and skinless chicken breast, the macronutrient differences are minimal. The key distinction lies in their micronutrient profiles, with pork offering superior B-vitamin levels, while chicken remains a great source of protein with very little fat. For a truly healthy diet, the optimal approach is not to favor one meat exclusively but to incorporate both, choosing lean cuts and healthy cooking methods to maximize their respective benefits.
