Why grass-fed beef and omega-3 eggs are better for you

Summary

Your body needs a good balance of two types of fats: omega-6 (common in grains and oils) and omega-3 (found in fish and grass). Too much omega-6 makes you more inflamed and prone to gaining weight. Animals fed grass or omega-3 supplements make meat and eggs with more healthy omega-3s.

Proposed Mechanism
ω-6/ω-3 PUFA imbalance drives inflammation via eicosanoid shift
Verified
ω-6 PUFAs promote adipogenesis via PPARγ and cAMP activation
Verified
ω-6 PUFAs enhance appetite and obesity via endocannabinoid system activation
Verified
Gut microbiota convert ω-6 LA to anti-inflammatory HYA and CLA metabolites
Verified
ω-3 PUFAs reduce hepatic and systemic inflammation via competitive inhibition of AA metabolism
Verified
FADS1 genetic variants modulate PUFA metabolism and inflammation risk
Verified
Rumen-protected ω-3 supplementation increases milk and meat ω-3 content via bypass of biohydrogenation
Verified
Pasture finishing increases ω-3 in beef via direct plant PUFA transfer and reduced biohydrogenation
