National pork tenderloin is a conical piece of lean meat found in the lower back of the pig, just above the kidneys. With 143 calories per 100 grams, this meat is noted for its low fat content of 3.5 g total and 1.2 g of saturated fatty acids. It is also rich in protein, providing 26 g per 100 g. It is important to store the tenderloin in the fridge in an airtight container, and if you wish to freeze it, it is recommended to cut it into portions and wrap them to maintain freshness. Cooking it on the grill enhances its juiciness; marinating beforehand can add extra flavor.
