The Claim

Eggs from hens supplemented with grass-fed beef suet and liver contain three times more odd-chain fatty acids (OCFAs) and 6–70 times more branched-chain fatty acids (BCFAs) than cage-free eggs, with PBB eggs containing 0.95% OCFAs and 0.59% BCFAs of total fatty acids, likely due to direct deposition from beef by-products.

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.

How it works
1 study reviewed
In plain English

Eggs from chickens fed beef fat and liver have way more of certain healthy fats than regular cage-free eggs — up to 70 times more in some cases — because the fats from the beef end up directly in the eggs.

  1. Study: Fatty Acid and Antioxidant Profile of Eggs from Pasture-Raised Hens Fed a Corn- and Soy-Free Diet and Supplemented with Grass-Fed Beef Suet and Liver

    The study shows that feeding hens grass-fed beef fat and liver makes their eggs much richer in certain healthy fats, just like the claim says.
