Earlier quoted context omitted.
That’s kind of a silly assumption frankly. Even on fish cans in the grocery store some advertise themselves as sustainably fished with certifications, and some don’t. Some egg cartons advertise themselves as “free range” and some don’t. Some meat advertises itself as “grass fed” and others don’t. The products themselves are telling you there are a variety of production standards and it is almost willful blindness to…
Grass-fed beef is advertised that way primarily for nutritional and taste claims and to support/explain the higher prices charged.
The reason people argue the meat is more nutritious is because the cows are healthier via eating their natural diet.
Corn diets cause health problems and bacterial infections requiring antibiotics.
Some of this will literally be on the websites of farms selling pastured beef. It’s not a big secret and if you seek out pastured beef it’s likely familiar.
