For anyone focused on a high-protein diet, a common question arises: which has more protein, chicken or pork? The answer is not as simple as it seems, and it depends heavily on the specific cut of meat chosen. While lean chicken breast is a powerhouse of lean protein, popular lean cuts of pork are very competitive. This guide provides a detailed breakdown of the protein content, as well as the overall nutritional profile, to help you make an informed decision for your dietary needs.
Protein Content in Lean Cuts
When comparing the leanest options, such as skinless chicken breast and pork tenderloin or loin steak, the protein levels are remarkably similar. However, chicken breast often has a slight edge in protein density.
- Chicken Breast: A 100g serving of cooked, skinless chicken breast can provide around 31-32 grams of protein. This is often the go-to choice for bodybuilders and those on low-fat diets due to its high protein-to-calorie ratio.
- Pork Tenderloin/Loin Steak: Cooked, lean pork tenderloin or loin steak typically contains about 30 grams of protein per 100g. This makes it an excellent, comparable alternative to chicken breast, especially for those seeking variety in their meals.
The Impact of Other Cuts
It's important to remember that not all cuts are created equal. Dark meat chicken, like thighs and drumsticks, contains more fat and fewer grams of protein per 100g compared to the breast. Similarly, fattier cuts of pork, such as pork belly or shoulder, will have significantly higher fat content and lower protein concentration than lean tenderloin. This difference in fat content can dramatically alter the overall macronutrient profile of a meal.
Beyond Protein: A Nutritional Breakdown
While protein is often the main consideration, a complete nutritional comparison involves examining the vitamins and minerals each meat provides. Both chicken and pork are rich in essential nutrients, but their strengths lie in different areas.
Vitamins and Minerals
- Pork's Advantages: Pork stands out for its rich content of certain B vitamins, particularly thiamin (B1) and cobalamin (B12). It is also a better source of zinc, selenium, and often provides more iron and phosphorus. Some cuts also contain Vitamins C and D, which are absent in chicken.
- Chicken's Advantages: Chicken is particularly high in niacin (B3) and pantothenic acid (B5), both of which are crucial for energy metabolism. It also provides a good source of potassium.
Comparison Table: Chicken Breast vs. Pork Tenderloin
| Nutrient (per 100g, cooked) | Lean Chicken Breast | Lean Pork Tenderloin |
|---|---|---|
| Calories | ~165 kcal | ~143 kcal |
| Protein | ~31g | ~21g (varies) |
| Total Fat | ~3.6g | ~5g |
| Saturated Fat | ~1.0g | ~1.6g |
| Vitamin B1 (Thiamin) | Lower | Higher |
| Vitamin B12 (Cobalamin) | Lower | Higher |
| Vitamin B3 (Niacin) | Higher | Lower |
| Zinc | Lower | Higher |
Fat Content and Caloric Density
For many, calorie and fat intake are just as important as protein. In a direct comparison of the leanest cuts, chicken breast consistently has lower fat and calorie counts per 100g than pork tenderloin. For instance, a 100g serving of skinless chicken breast is around 165 calories with 3.6g of fat, while a comparable pork tenderloin might be around 143 calories but with a slightly higher fat content of 5g. The fat content varies significantly across different cuts of pork, from the very lean tenderloin to the high-fat pork belly.
Choosing the Right Meat for Your Goals
Your dietary goals and personal health factors should dictate your choice between chicken and pork. Both are fantastic sources of high-quality protein, but cater to different needs:
- For Weight Loss and Lean Muscle: Lean chicken breast is often preferred. Its low fat and calorie content relative to its high protein density make it a top choice for managing calorie intake while building muscle.
- For Nutrient Variety: If you're looking to maximize your intake of specific nutrients like thiamin, B12, and zinc, incorporating lean pork tenderloin into your diet can be a great strategy. It offers a slightly different nutritional profile that complements chicken well.
- For Flavor and Cooking: Pork tenderloin is often praised for its rich flavor and tenderness, providing a juicy alternative to the milder chicken breast. Experimenting with different cooking methods, seasonings, and marinades can unlock the best of both meats.
Conclusion
While lean chicken breast may hold a slight edge in pure protein density per 100 grams, lean pork is a very strong contender and, in some cases, even offers slightly more protein depending on the cut and source. However, the choice is about more than just protein numbers. Pork is a superior source of certain B vitamins and minerals like zinc, while chicken offers excellent protein with a lower fat and calorie count. Both meats provide high-quality protein and have a valuable place in a balanced diet. The best approach for optimal nutrition is to incorporate a variety of lean protein sources, including both chicken and pork, to benefit from their unique nutritional advantages.

Frequently Asked Questions
What's the best way to choose between chicken and pork?
To choose, consider your specific health and dietary goals. If your priority is a low-calorie, high-protein meal for weight loss, skinless chicken breast is likely the better option. If you want more variety and a boost of specific nutrients like B12 and zinc, lean pork tenderloin is an excellent choice.
Is pork considered red meat, and does it matter?
Yes, pork is officially classified as red meat, while chicken is white meat. While some past health concerns were associated with red meat, lean pork cuts can be part of a healthy diet, much like chicken. Cooking method and frequency are more significant factors for health.
Are pork tenderloin and chicken breast nutritionally similar?
Yes, cooked lean pork tenderloin and cooked skinless chicken breast are very comparable in terms of protein, fat, and calorie content. They differ slightly in their vitamin and mineral profiles, but both are excellent lean protein sources.
Does the cooking method affect the protein content?
No, the cooking method does not significantly change the protein content. However, it can affect the fat and calorie content. For example, frying adds more fat and calories than baking or grilling, which can alter the overall nutritional profile.
Is one meat inherently 'healthier' than the other?
Neither is inherently healthier; both are nutritious choices. The healthiness of the meal depends on the cut of meat, preparation method, and overall dietary pattern. Lean cuts of both can support a healthy lifestyle.
How much protein is in a standard serving of each?
A standard 3-ounce (85g) serving of cooked, lean skinless chicken breast contains roughly 26-27 grams of protein, while a 3-ounce serving of lean pork loin can offer about 23 grams of protein.
Which meat is better for muscle building?
Both are excellent for muscle building, as they are complete protein sources containing all essential amino acids. Because it is often lower in fat and calories, chicken breast is a classic choice for muscle growth when calorie control is key. However, adding variety with lean pork is also highly beneficial.
Which has more vitamins and minerals, chicken or pork?
Pork is generally richer in vitamins and minerals like Thiamin, B12, and zinc, while chicken contains more Niacin and B5. Both provide a range of essential nutrients, so incorporating both into your diet can provide a broader spectrum of micronutrients.
