Why is lamb good for you?

  • 24 g protein in 3 oz roasted, 48% of the daily value. Protein contributes to the maintenance of muscle mass.
  • 1.8 mg iron in 3 oz roasted, 10% of the daily value. Iron contributes to the normal formation of red blood cells.

Good ways to use it

  • Roasts and kebabs
  • Stews with vegetables

What should you watch out for?

  • Red meat: keep to a few portions a week. Fattier cuts like chops and ribs are much higher in saturated fat.

Which meat and fish score higher?

Other meat and fish with more nutrition per calorie. Variety matters more than picking one winner.
