The Claim

Grass-finished beef has a significantly lower n-6:n-3 fatty acid ratio (1.61:1) than grain-finished beef (8.36:1), resulting in a more balanced omega fatty acid profile associated with reduced inflammation.

Description
1 study reviewed
In plain English

Grass-finished beef contains a lower ratio of omega-6 to omega-3 fatty acids compared to grain-finished beef, leading to a fatty acid profile that is more balanced.

See the scientific wording

Grass-finished beef has a significantly lower n-6:n-3 fatty acid ratio (1.61:1) compared to grain-finished beef (8.36:1), indicating a more balanced profile of omega fatty acids that may reduce inflammation.

Why this might work

When people eat grass-finished beef, the fats in the meat change the types of fats in their cell membranes. This shift causes the body to make fewer inflammatory signaling molecules and more anti-inflammatory ones, leading to less inflammation.

  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 a much better balance of healthy omega-3 fats compared to unhealthy omega-6 fats than beef from cows fed grain — exactly as the claim says. This better balance may help reduce inflammation in the body.
