What makes some eggs healthier than others?
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

Surprising Findings
Eggs contained up to 70 times more branched-chain fatty acids (BCFAs) when hens were fed beef liver and suet.
BCFAs are almost exclusively found in ruminant fats like beef and dairy — not in eggs. Seeing them spike this high suggests direct nutrient transfer from animal-to-animal via feed.
Practical Takeaways
Choose pasture-raised eggs, especially from farms using diverse, non-soy feeds, for better omega-3s and lower inflammation-promoting fats.

Pasture-raised eggs are more nutritious than regular cage-free eggs — they’ve got more of the good stuff like omega-3s and antioxidants, and a better fat balance that could help keep your heart healthier.
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.
If you feed pasture-raised chickens extra grass-fed beef fat and liver, their egg yolks end up with five times more 'good fat' called CLA — about 0.05 grams in every 100 grams of yolk — compared to eggs from chickens on regular feed.
Eggs from hens fed a special diet with grass-fed beef leftovers have way less unhealthy fat and a much better balance of good fats compared to regular cage-free eggs.
