Beef: A good source of iron, protein, and vitamin B12. The most lean and nutrient dense cuts of beef are the round, tenderloin, sirloin, and flank. All beef however is not created equal. Just as you are what you eat, so the nutritional value of the beef depends on it's diet.

    A sirloin steak from a grass fed steer has about one half to one third the amount of saturated fat as a similar cut from a grain fed steer or approximately equivalent to that of skinless chicken. If you eat a typical amount of beef (66.5 pounds a year), switching to grassfed beef will save you 17,733 calories a year. If everything else in your diet remained constant, you'd lose about six pounds a year from this alone. Although grassfed meat is lower in saturated fat, it gives you from two to six times more "omega-3 fatty acids." Grassfed meat is higher in conjugated linoleic acid and vitamin E. Grassfed steers are not fed poulty litter, (read “chicken crap”) and offal (meat scraps from animals including bone meal from other cows mixed with pig blood), a know cause of mad cow disease.

    Lastly, feed grain is not organic so cows get to pass along all of the pesticides and fertillizers they consume and absorb. Prefer lean cuts of organic grassfed beef guaranteed free of antibiotics and growth hormones.
