The Claim
The term 'grass-fed' in the United States lacks a legally enforceable definition, allowing animals to be labeled as grass-fed even when they receive significant grain-based supplemental feed.
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.
In the United States, there is no legal standard for the term 'grass-fed,' so animals can be labeled as grass-fed even if they are fed a lot of grain.
See the scientific wording
The term 'grass-fed' lacks a legally enforceable definition in the United States, permitting animals to be labeled as grass-fed despite receiving significant grain-based supplemental feed.
Without a legal rule defining what 'grass-fed' means, producers can call meat grass-fed even when animals eat a lot of grain, so the label does not reliably show what the animals ate.
What the research says
1 studyThe study found that some beef labeled 'grass-fed' actually has the same nutrition as grain-fed beef, meaning the label doesn't always mean what people think. This supports the idea that there's no strict rule for what 'grass-fed' really means.
