The Benefits of Grass-Fed Beef: A Healthier and More Sustainable Choice
If you're a meat-eater, you may be wondering about the differences between conventional beef and grass-fed beef. While both types of beef come from cows, there are some important differences in terms of nutrition, sustainability, and animal welfare.
One of the biggest differences between conventional beef and grass-fed beef is the nutritional profile. Grass-fed beef is lower in total fat and saturated fat than conventionally-raised beef[^1]. It's also higher in protein, heart-healthy omega-3 fatty acids, and antioxidants like vitamin E[^2]. Grass-fed beef is also a good source of vitamin B12, iron, and zinc, all of which are important for overall health.
Another benefit of grass-fed beef is that it's more sustainable than conventional beef. Grass-fed cows are typically raised on pasture, which means they require less fossil fuel to produce than cows raised in feedlots[^3]. Plus, grass-fed beef is often produced using more sustainable farming practices, such as rotational grazing, which helps to maintain healthy soil and reduce erosion[^4].
In addition to being healthier and more sustainable, grass-fed beef is often considered to be more humane than conventionally-raised beef. Grass-fed cows are typically raised in a more natural environment, with access to pasture and room to roam[^5]. This can lead to improved animal welfare, as well as improved taste and texture in the meat.
If you're interested in trying grass-fed beef, make sure to look for meat that has been certified by a third-party organization, such as the American Grassfed Association or Certified Grassfed by AGW[^6]. These certifications ensure that the meat comes from cows that have been raised on pasture and fed a diet of grass and forage.
