The 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
This study is like taking a snapshot of different types of eggs to see what’s inside. It shows that eggs from hens fed certain diets have more of some nutrients, but it can’t prove that the diet caused the change because other factors might be involved.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Eggs from hens that eat grass and special beef leftovers are healthier because they have better fats and more good stuff like vitamins.

Claims (5)
Eggs from hens fed grain instead of their natural diet of pasture and insects contain higher levels of pro-inflammatory lipids.
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.
