Eating foods with added plant sterols—like certain margarines or orange juices—can lower your 'bad' cholesterol by about 0.55 mmol/L, which might help reduce your risk of heart disease.

Assessment Explanation
The claim uses 'associated with' and 'may contribute,' which correctly reflect the observational and meta-analytic evidence base. RCTs and meta-analyses consistently show phytosterol intake reduces LDL-C by ~0.3–0.5 mmol/L, with 0.55 mmol/L being a plausible upper estimate from high-dose or prolonged intake. The phrase 'may contribute to cardiovascular risk reduction' is appropriately cautious, as direct cardiovascular outcome data (e.g., heart attacks) are limited and inferred from LDL-C lowering. No overstatement is present.
More Accurate Statement
“Consumption of phytosterol-fortified foods is associated with an average reduction in low-density lipoprotein cholesterol (LDL-C) levels of approximately 0.55 mmol/L in adults, which may contribute to a reduction in cardiovascular risk.”

This study looked at many experiments and found that eating foods with added plant sterols (like fortified margarine or bread) lowers bad cholesterol by about 0.55 mmol/L — just like the claim says.
