Corned beef is my favorite breakfast meat but I learned that it comes from beef brisket, the fatty area of beef brisket. So, yes, sad face to the highest level – one serving contains 960 mg of sodium which is almost over the daily recommended allowance. It also has 5 grams of bad fat and 16 grams of healthy fat. It is packed with nitrates too. So, it’s a bit unhealthy.
