Pork may be known as "the other white meat," but it doesn't usually top the list when we think of lean protein. We can probably thank bacon for that, but not all pork is dripping in fat and packed with sodium. Pork loin, for instance, is actually quite lean, low in fat, carbs and calories. Learning how to bake a pork loin can add a nice punch of variety and flavor to your diet whether you're watching your weight, trying to eat more healthfully or just looking for interesting new options for your usual dinner rotation.
