The Claim

Grass-finished beef contains significantly higher levels of vaccenic acid (C18:1 t11) and conjugated linoleic acid (CLA) than grain-finished beef, and these compounds are associated with metabolic and anti-inflammatory benefits.

Description
1 study reviewed
In plain English

Grass-finished beef has more vaccenic acid and conjugated linoleic acid than grain-finished beef, and these compounds are linked to metabolic and anti-inflammatory effects.

See the scientific wording

Grass-finished beef contains significantly higher levels of vaccenic acid (C18:1 t11) and conjugated linoleic acid (CLA) than grain-finished beef, compounds associated with potential metabolic and anti-inflammatory benefits.

Why this might work

When cows eat grass, bacteria in their stomach break down plant fats and turn them into two specific fats called vaccenic acid and conjugated linoleic acid. These fats build up in the cow’s muscle tissue and end up in the meat.

What the research says

1 study
  1. Study: Fatty Acid and Micronutrient Profile of Longissimus Lumborum from Red Angus and Red Angus x Akaushi Cattle Finished on Grass or Grain

    This study found that beef from cows that ate grass has more of two special fats—CLA and vaccenic acid—than beef from cows that ate grain. These fats might help with metabolism and reduce inflammation.
