If you eat phytosterols in bread or cereal, they don’t lower your bad cholesterol as much as when you eat them in butter or margarine—by about 0.14 mmol/L less.

Assessment Explanation
The claim uses 'associated with,' which correctly reflects observational or intervention study findings without implying direct causation. The quantitative difference (0.14 mmol/L) is precise and plausible based on meta-analyses of phytosterol delivery vehicles. The claim does not overstate causality, and the comparison between food matrices is a well-studied topic in nutritional science. The phrasing is scientifically sound.
More Accurate Statement
“Phytosterols delivered in bread, biscuits, or cereals are associated with a smaller reduction in LDL cholesterol (by approximately 0.14 mmol/L) compared to phytosterols delivered in butter, margarine, or spreads.”

Use of phytosterol-fortified foods to improve LDL cholesterol levels: A systematic review and meta-analysis.
The study found that when phytosterols are added to bread or cereal, they lower bad cholesterol a little less than when they’re added to butter or margarine — just like the claim says.
