The article explores how the fat color in beef is indicative of the cow's diet, distinguishing between white fat from grain-fed cows and yellow fat from grass-fed cows. It explains that beta-carotene, found abundantly in grass, is responsible for the yellow hue, while grain-fed diets contribute to the white fat appearance due to lower pigment content. Additionally, it touches on health comparisons, suggesting grass-fed beef may be healthier due to higher vitamin A content and lower antibiotic use compared to grain-fed beef.
When buying a cut of beef, the fat-marbling color reflects the type of feed the cow received: white for grain-fed and yellow for grass-fed.
Grass-fed cows have yellow fat due to their high beta-carotene diet, while grain-fed cows produce white fat with lower pigment content.
