Understanding the Nutritional Profile of 4 oz of Pork
The nutritional makeup of a 4 oz (113g) serving of pork can differ greatly depending on the cut and cooking method. While all pork is a rich source of high-quality protein, the calorie and fat content are key variables to consider. Leaner cuts such as tenderloin offer a much different profile than fattier, less-trimmed options.
Macronutrient Breakdown by Pork Cut
To illustrate the variations in pork's nutritional content, let's examine the macronutrient breakdown of a 4 oz serving (cooked) for two common cuts: pork tenderloin and blade-in pork chops. This comparison highlights how your choice of cut impacts your overall nutrient intake.
- Pork Tenderloin: A 4 oz roasted tenderloin is notably lean, providing around 162 calories, 30g of protein, and only 4g of total fat, with about 1g of saturated fat. Its low-fat, high-protein nature makes it a very heart-healthy choice.
- Bone-in Pork Chops: A 4 oz pan-fried, bone-in pork chop (separable lean only) contains approximately 252 calories, 30g of protein, and 14g of total fat, with 3g of saturated fat. This shows a significantly higher fat and calorie count compared to the tenderloin.
Micronutrients: A Wealth of Vitamins and Minerals
Beyond protein and fat, 4 oz of pork offers a substantial amount of essential vitamins and minerals crucial for bodily function. The B-vitamins are particularly abundant, supporting energy metabolism and nervous system health.
- Vitamins:
- B-vitamins: Pork is a fantastic source of thiamine (B1), niacin (B3), pyridoxine (B6), and cobalamin (B12). Thiamine, in particular, is very high in pork compared to other red meats. These vitamins are vital for converting food into energy and maintaining overall well-being.
- Choline: An essential nutrient found in pork, choline is important for brain function and development, especially during pregnancy.
- Minerals:
- Selenium: Pork is a rich source of selenium, an important antioxidant.
- Zinc: Zinc, essential for a healthy immune system and metabolic function, is also found in significant quantities.
- Phosphorus: This mineral is critical for body growth and maintenance and is abundant in pork.
- Iron: Pork provides a good amount of iron, important for healthy red blood cells.

Health Benefits and Considerations
Incorporating pork into a balanced diet can offer several health benefits, especially when choosing leaner cuts and preparing them properly. The high protein content supports muscle growth and maintenance, and it can also aid in weight management by increasing satiety. The rich vitamin and mineral profile supports everything from cognitive function to the immune system. However, it's crucial to be mindful of how pork is prepared and the cut chosen. Processed pork products like bacon and sausages, or fattier cuts, can be high in sodium and saturated fat, which may increase the risk of heart disease when consumed excessively. The safest way to enjoy pork is to cook it to the recommended internal temperature of 145°F and trim any visible fat.
Conclusion
In conclusion, the nutritional value of 4 oz of pork is highly dependent on the specific cut and preparation. Lean options like tenderloin are excellent, protein-packed, low-fat choices rich in B-vitamins, selenium, and zinc. Fattier cuts offer a different nutritional profile with more calories and saturated fat. By selecting leaner cuts and opting for healthy cooking methods, pork can be a valuable and nutritious part of a balanced diet, providing essential nutrients that support overall health and muscle function.
