Assessment Explanation
The phrase 'beneficial effects' is definitive but unsupported by new data in this review. As a narrative summary, it cannot establish benefit. The claim must be downgraded to reflect association with prior reports.
More Accurate Statement
“Conjugated linoleic acid has been associated with potential health benefits in prior studies, though this review does not provide new evidence to confirm these effects.”
