Pastured meat and eggs may boost Omega-3 levels, study finds
NCT ID NCT06768775
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether eating meat and eggs from pastured (regenerative) farms affects health differently than conventional products. Eighty middle-aged adults ate either pastured or conventional chicken, beef, pork, and eggs for 16 weeks. Researchers measured omega-3 fatty acids in red blood cells and other health markers to see if the farming method makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pastured livestock diet (meat and eggs from regenerative farming)
- What this could lead to
- If it works, this could show that eating pastured animal products improves omega-3 levels and other health markers compared to conventional products.
- What could go wrong
- This is a small, completed observational-style trial with only 80 participants. Results may not apply to everyone, and any differences found might be small or not meaningful for health.
