The Claim
Beef from cattle fed exclusively on corn grain contains significantly higher concentrations of volatile compounds associated with lipid oxidation than beef from cattle finished on legume-grass pasture with or without grain supplementation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Beef from cattle fed only corn grain has more chemical compounds linked to spoilage than beef from cattle raised on grass and legumes, with or without grain.
See the scientific wording
Beef from cattle fed exclusively on corn grain has significantly higher levels of volatile compounds associated with lipid oxidation compared to beef from cattle finished on legume-grass pasture with or without grain supplementation, suggesting greater susceptibility to rancidity.
When cattle eat grass and legumes, they take in omega-3 fats that get stored in their muscle cells. These fats replace other fats that break down easily when exposed to air, making the meat less likely to develop bad smells. Corn-fed cattle get more of the fats that break down quickly, leading to more chemicals that cause rancidity.
What the research says
1 studyBeef from cows fed only corn tastes more rancid than beef from cows that ate grass, because corn-fed beef produces more chemicals that cause bad smells when fat breaks down.
