The more phytosterols you eat each day—like in fortified margarine or orange juice—the more your 'bad' cholesterol (LDL) goes down, and this pattern keeps happening as you eat more.

Appropriate Language Strength
association

Assessment Explanation
The claim uses 'associated with,' which correctly reflects observational and intervention studies that show a trend but do not prove causation. Dose-response relationships are commonly observed in nutritional trials with phytosterols, and the wording avoids implying direct causation. The claim is appropriately cautious and aligns with existing meta-analyses showing consistent dose-dependent LDL-C lowering.
More Accurate Statement
“In individuals consuming phytosterol-fortified foods, higher daily doses of phytosterols are associated with greater reductions in LDL-C levels, suggesting a dose-response relationship.”

Use of phytosterol-fortified foods to improve LDL cholesterol levels: A systematic review and meta-analysis.
The study found that the more phytosterols people ate through fortified foods like margarine or cereal, the more their bad cholesterol (LDL) went down — so yes, more phytosterols = better cholesterol results.
