When hamsters eat a fatty, cholesterol-rich diet, giving them a special form of plant-based cholesterol blockers in tiny fat bubbles helps lower their bad cholesterol.

Assessment Explanation
The claim uses 'associated with,' which is appropriate for preclinical animal studies where causality cannot be definitively proven without controlled mechanistic experiments. The use of liposomal delivery, specific phytosterol composition, and a defined diet model suggests a well-constrained experimental context. However, 'associated with' is weaker than 'reduces'—the latter would imply causality without sufficient mechanistic or dose-response data. The current phrasing is scientifically cautious and accurate for the context.

Liposomal Phytosterols as LDL-Cholesterol-Lowering Agents in Diet-Induced Hyperlipidemia.
Scientists gave hamsters a special fat-fighting supplement made from plant chemicals in canola oil, and the hamsters' bad cholesterol went down — just like the claim said it would.
