The Claim

Beef from cattle finished on legume-grass pasture with or without corn grain supplementation has a significantly lower n-6/n-3 fatty acid ratio and higher levels of conjugated linoleic acid (C18:2 cis-9 trans-11) than beef from cattle fed only corn grain, resulting in a lipid profile more favorable for human consumption.

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 from cattle raised on legume-grass pasture, with or without corn grain, contains a lower ratio of omega-6 to omega-3 fatty acids and more conjugated linoleic acid than beef from cattle fed only corn grain, leading to a lipid profile that is more favorable for human health.

See the scientific wording

Beef from cattle finished on legume-grass pasture with or without corn grain supplementation has a significantly lower n-6/n-3 fatty acid ratio and higher levels of conjugated linoleic acid (C18:2 cis-9 trans-11) compared to beef from cattle fed only corn grain, which may contribute to a more favorable lipid profile for human consumption.

Why this might work

When cows eat grass and legumes, their stomachs convert plant fats into healthier fats that end up in their meat. These healthier fats reduce the imbalance between two types of fatty acids and increase a specific beneficial fat called CLA, making the meat better for human health.

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

    Cows that eat grass and legumes, even if they get a little corn too, produce beef with healthier fats and more beneficial compounds than cows fed only corn. This makes the beef taste better and may be better for your heart.
