Unlike “organic” and “free-range”, the term “grass fed beef” is not legally defined and so different meat suppliers can use it to mean different things. Generally speaking however, “grass fed” refers to beef that comes from cattle that have primarily grazed on grass throughout the course of their lives. This is unlike the more common “grain fed beef’ that you find in supermarkets; beef from cows that eat solely grain-based feeds composed of soy or corn.
Grass fed beef almost always contains a lower content of total fat than grain fed beef, meaning that per gram, the calorific content of grass fed beef will be lower. Beyond calorie count though, grass fed beef is widely considered to be (1) healthier, (2) better tasting, and (3) more ethical than solely grain fed beef!
Besides overall fat quantity, it's also the specific make up of fat from grass fed beef that makes it healthier than grain fed beef.
Because grass fed beef comes from cows that are usually free range, their muscles are put to significantly more work than feedlot cattle, making their beef significantly more lean with less marbling. Marbling (those strands of intermuscular fat) is the primary source of taste in grain fed beef, giving it those slightly sweeter tones you’ve no doubt tasted in supermarket, grain fed beef.
Because grass fed beef has significantly more minerals and vitamins (besides it’s subtle yet also present fat contents), the range and richness of flavors — often described as “meaty”, “gamey” or “premium” – is stronger. It is these taste profiles that strongly attract Michelin Star Chefs to grass fed beef.
As previously mentioned, grass fed beef comes from cows that have lived free range lives, able to exercise natural behaviours such a foraging and grazing at will. More broadly, their stress levels are lower throughout life and have been consistently proven to be far less likely to catch illnesses. This is in contrast to grain fed cows that usually spend their days in feedlots, eating grains that are very high in calories, encouraging them to grow at harmfully fast rates; diminishing the strength of their underdeveloped joints and in turn their natural mobility.Buy Grass Fed, Sustainable beef
