The Claim
Grass-finished beef contains higher concentrations of iron and vitamin E compared to grain-finished beef, resulting in increased antioxidant capacity and improved meat stability.
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.
Grass-finished beef has more iron and vitamin E than grain-finished beef, leading to greater antioxidant capacity and better stability during storage.
See the scientific wording
Grass-finished beef contains significantly higher levels of iron and vitamin E than grain-finished beef, which may enhance its antioxidant capacity and contribute to better meat stability.
Cows that eat grass consume more plant pigments and nutrients, which get stored in their muscles as vitamin E and iron. These nutrients work together to protect fats in the meat from breaking down when exposed to air, keeping the meat fresher longer.
What the research says
1 studyThis study found that beef from cows that ate grass has more iron and vitamin E than beef from cows that ate grain, which helps keep the meat from going bad faster and may be healthier for you.
