Grass-fed beef comes from cattle that have been raised primarily on a diet of grass and forage, rather than grain. This method of raising cattle is believed to promote better animal welfare and can lead to healthier meat. Grass-fed cattle typically graze on pasture, which allows them to engage in natural behaviors. The nutritional profile of grass-fed beef differs from that of grain-fed beef. It often contains higher levels of omega-3 fatty acids and antioxidants, which can be beneficial for health. Additionally, grass-fed beef is usually leaner, with less overall fat content compared to its grain-fed counterpart.
