The Claim
Beta-carotene derived from grass accumulates in the adipose tissue of cattle, leading to visible yellow coloration of fat.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When cattle eat grass, the beta-carotene in the grass builds up in their fat tissue and turns the fat yellow.
See the scientific wording
Beta-carotene from grass accumulates in the adipose tissue of cattle, resulting in visibly yellow fat coloration.
When cattle eat grass, they absorb beta-carotene from it. Their bodies have enzymes that normally break down beta-carotene into other compounds, but these enzymes work very slowly in cattle. Because the breakdown is too slow, beta-carotene stays in the bloodstream and gets stored in fat tissue, where it gives the fat a yellow color.
What the research says
2 studiesCows eat grass that has beta-carotene, but their bodies don’t break it down well, so it builds up in their fat and turns it yellow. Goats break it down quickly, so their fat stays white.
When cows eat grass, they absorb a yellow pigment called beta-carotene, and their bodies don’t break it all down — so it stays in their fat and makes it look yellow. The study found that even when cows try to break it down more, the pigment still builds up.
