Understanding Lean Pork and Its Protein Content
Pork is often overlooked as a lean protein source, but many cuts offer a significant amount of high-quality, complete protein with less fat than previously thought. A 1-ounce serving is a small but useful portion for portion-control or for calculating the nutritional value of a larger meal. The protein content can vary based on whether the pork is raw or cooked, as cooking removes moisture and concentrates the nutrients. The following sections explore the specific protein amounts for different types of lean pork cuts.
Protein in Cooked Lean Pork Cuts
When pork is cooked, water evaporates, which increases the protein density per ounce compared to raw meat. For example, a cooked, broiled 1-ounce serving of separable lean pork loin contains a substantial amount of protein, making it an efficient source for muscle maintenance and growth.
Here is a look at the approximate protein amounts in 1 oz of popular cooked lean pork cuts, based on USDA data:
- Pork Tenderloin (cooked, roasted): Contains approximately 8 grams of protein per ounce. This is a very lean cut and a popular choice for health-conscious diners.
- Ground Pork (cooked, 96% lean): Contains around 8.7 grams of protein per ounce in crumbles. The cooking process concentrates the protein, providing a solid nutritional punch for its size.
- Pork Loin (cooked, pan-fried): An ounce of pan-fried boneless loin, lean only, yields about 9 grams of protein. This cut offers a slightly higher protein concentration due to the cooking method.
These figures demonstrate that even a small 1-ounce serving contributes meaningfully to your daily protein intake.
Protein in Raw Lean Pork Cuts
For those who prefer to measure nutrients before cooking, the protein content of raw lean pork is also important to consider. The protein amount in raw meat will be lower per ounce than in its cooked counterpart due to the higher water content.
- Pork Tenderloin (raw, lean only): Contains approximately 5.95 grams of protein per ounce. This is the starting point before any cooking shrinkage occurs.
- Pork Loin (raw, lean only): A 1-ounce portion of raw, separable lean pork loin has about 6 grams of protein.
Understanding the difference between raw and cooked figures is vital for accurate calorie and macronutrient tracking. A 3-ounce portion often recommended by dietitians would therefore contain a proportionally higher protein count when cooked.
Lean Pork vs. Other Protein Sources
Comparing lean pork to other popular protein sources helps put its nutritional value into perspective. Both chicken and lean beef are often seen as the go-to choices for high-protein, low-fat diets, but pork holds its own.
| Protein Source | Protein per 1 oz (cooked) | Fat per 1 oz (cooked) | Notes |
|---|---|---|---|
| Lean Pork (Tenderloin) | Approx. 8-9g | Approx. 1-2g | Often comparable to skinless chicken breast in leanness and protein content. |
| Skinless Chicken Breast | Approx. 9-10g | Approx. <1g | Slightly higher in protein per ounce, but pork offers a comparable profile. |
| Lean Beef (90/10) | Approx. 7g | Approx. 3g | Higher fat content than lean pork cuts. |
| Cod (Cooked) | Approx. 6g | Approx. <1g | Leaner, but with less protein per ounce than lean pork. |
This comparison highlights that lean pork is a highly competitive and nutritionally sound option. Pork tenderloin, in particular, is an excellent choice for those seeking a lean protein.
Beyond Protein: A Look at Other Nutrients
Lean pork is not just about protein; it is also a rich source of many essential vitamins and minerals.
- B Vitamins: Especially high in Thiamin (B1), Niacin (B3), B6, and B12, which are vital for energy metabolism and brain function.
- Minerals: A good source of selenium, zinc, and phosphorus.
- Amino Acids: As a complete protein, pork contains all nine essential amino acids needed for muscle repair and maintenance.
Cooking Lean Pork for Optimal Protein
The way you cook lean pork can affect its final nutritional content, though not significantly altering the protein percentage. Grilling, roasting, and pan-frying are excellent methods for preparing lean cuts like tenderloin, as they require minimal added fats. Overcooking, however, can make the meat dry and less palatable, so it's important to cook to the correct internal temperature (145°F/63°C followed by a rest). This ensures safety while maintaining moisture and flavor.
For ground pork, cooking until it is fully browned and broken into crumbles is best. Roasting larger cuts like a pork loin will allow for even cooking and moisture retention. Trimming any visible excess fat before cooking is another way to ensure the final product remains as lean as possible.
Conclusion
To answer the question of how much protein is in 1 oz of lean pork, the amount typically ranges from 8 to 9 grams for a cooked portion. Specific cuts like tenderloin and 96% lean ground pork offer a concentrated source of protein, making them an excellent dietary choice. When measured raw, the protein content per ounce is lower due to water weight, but still substantial. This high-quality protein, combined with a rich profile of B vitamins and essential minerals, makes lean pork a valuable addition to a balanced and healthy diet.

For more in-depth nutritional data and research, consult the USDA FoodData Central database. The USDA is the authoritative source for food composition and provides extensive details on countless food items, including various cuts of pork. Using this resource allows for precise nutritional calculations for any serving size.
