The Claim

Supplementing legume-grass pasture with whole corn grain during beef finishing does not significantly alter the fatty acid profile, volatile compound levels, or off-flavor intensity of beef compared to finishing on legume-grass pasture alone.

Source: Effects of feeding legume-grass pasture and different concentrate levels on fatty acid profile, volatile compounds, and off-flavor of the M. longissimus thoracis.

Description
1 study reviewed
In plain English

Beef finished on legume-grass pasture with added whole corn grain has the same fatty acid profile, volatile compound levels, and off-flavor intensity as beef finished on legume-grass pasture without grain.

See the scientific wording

Supplementing legume-grass pasture with whole corn grain does not significantly alter the fatty acid profile, volatile compound levels, or off-flavor intensity of beef compared to pasture-only finishing, suggesting minimal impact of moderate grain supplementation on meat quality.

Why this might work

When cattle eat legume-grass pasture, they consume omega-3 fatty acids that get stored in their muscle fat. These fatty acids change the type of fats in the muscle, making them less likely to break down into bad-tasting chemicals when the meat is stored or cooked. Adding a small amount of corn to this diet does not change this process because the omega-3 fats from the grass still dominate the fat composition, so the meat tastes the same as if no corn was added.

    Adding a little corn to grass-fed cows' diet doesn't change the taste or fat quality of their beef — it's still just as healthy and tasty as beef from cows that ate only grass. But feeding them only corn makes the beef taste worse.
