As far as I’m aware, there are no strict regulations over whether meat can be called ‘grass-fed’ or ‘grain fed’ so it’s likely that even within these different classifications there will be a wide variation in the nutritional quality of the meat. Grass-fed beef is generally higher in omega-3 fatty acids than grain-fed, but this depends on the type of grass the animal feeds on. Other nutrients such as iron and zinc are more likely to be linked to the animal’s age, not their feeding regime. Overall I would say the more important consideration is that you consume a variety of meat, including fish, during the week and balance your meat intake with plenty of vegetables or salad.
