You may have heard of the expression 'nutrient density'. Foods containing a healthy dose of essential nutrients compared to their calories are said to have a high nutrient density. Pure sugar, for example, provides lots of calories, and nothing else. This is an example of low nutrient density, or 'empty calories'. Lean meats like pork are great examples of foods with high nutrient density.
Pork is packed with high quality protein, B vitamins and key minerals such as iron and zinc.
As a bonus, pork is leaner than ever.
