Grass-Fed Beef

Grass-fed beef has a lower omega-6 to omega-3 ratio than grain-fed beef, indicating a higher relative abundance of omega-3 fatty acids. Grass-fed beef contains lower levels of advanced glycation end products (AGEs), which are a major negative health marker linked to accelerated aging. Hirsutin, a major polyphenol present at higher levels in grass-fed beef, is associated with improved gut microbial diversity and lower risk of metabolic syndrome. Grass-fed, grass-finished beef is biochemically distinct from processed meat and fast-food beef and should not be categorized with them. The label 'grass-fed' alone, without 'finished,' does not guarantee the animal was not grain-finished. The highest-performing beef in the nutrient-density study came from pastures with high weed diversity and relatively less grass. Metabolomic testing can detect nutritional differences between grass-fed and grain-fed beef that category-level epidemiology cannot distinguish. Greater diversity of plant species in an animal's pasture drives a more diverse cattle gut microbiome, resulting in higher phytonutrient and vitamin content in the meat. Elevated homocysteine is an established biomarker for cardiovascul…
