This special broccoli lowers bad cholesterol about as much as other well-known heart-healthy foods like oats or plant sterols.
Scientific Claim
High glucoraphanin broccoli reduces plasma LDL cholesterol to a similar extent as oat beta-glucans or plant stanols, which are established dietary interventions for cholesterol management.
Original Statement
“HG broccoli reduces LDL-C to a greater extent than standard broccoli... and to a similar amount to that following intake of oat β glucans and plant stanols.”

Assessment Explanation
The claim compares effect sizes from this RCT to published data from other studies. While the HG broccoli effect is directly measured, the comparison to other interventions is based on external evidence, warranting probabilistic language.
More Accurate Statement
“High glucoraphanin broccoli reduces plasma LDL cholesterol by a magnitude similar to that observed with oat beta-glucans or plant stanols in other studies.”

Diet rich in high glucoraphanin broccoli reduces plasma LDL cholesterol: Evidence from randomised controlled trials
This study shows that a special kind of broccoli can lower bad cholesterol, but it didn’t compare it to oatmeal or plant-based cholesterol-lowering foods, so we can’t say it works just as well as them.
