Pork tenderloin is a protein-rich food that is a lean form of red meat, making it a good addition to your diet. Here's what you need to know about pork tenderloin's calorie and nutrition quotient. Careful though, pork tenderloin is not the same as pork loin.
A 4-ounce serving of pork tenderloin has 136 calories.
Pork Loin vs. Pork Tenderloin
Pork tenderloin is not to be confused with pork loin. While both cuts are from the loin section that runs along the pig's back, from the shoulder to the top of the legs, the National Pork Board explains that they are different cuts of meat. Pork loin is usually sold as a wide, rectangular slab of meat that can be cut into steaks. It weighs between 2 to 4 pounds and is sold either bone-in or deboned.
Pork tenderloin on the other hand, is a smaller, longer cut that usually weighs around 1 pound. The University of Tennessee Extension notes that this cut of meat tapers off on one end. The wider end is about 2 inches thick.
It's important to know the difference between these two cuts of meat, especially when you're shopping at the grocery store. If you buy the wrong one and try to cook it, chances are your meal will be a disaster, because the ingredient proportions and the cooking times and temperatures for both these cuts are different, since they are quite different in size.
