The special broccoli lowers bad cholesterol equally well whether your cholesterol was already high or just a little elevated, but regular broccoli only helps if your cholesterol was already high.
Scientific Claim
The reduction in LDL cholesterol from high glucoraphanin broccoli is not dependent on baseline LDL levels, whereas standard broccoli’s effect is stronger in individuals with higher baseline LDL.
Original Statement
“The reduction in LDL-C by HG broccoli was not dependent upon baseline LDL levels... in contrast to that of standard broccoli that was significantly associated (% ΔLDL-C = 18.8–4.8LDL-Cbaseline, r2 = 13.7%, p = 0.001).”

Diet rich in high glucoraphanin broccoli reduces plasma LDL cholesterol: Evidence from randomised controlled trials
The study shows that special broccoli lowers bad cholesterol better than regular broccoli, but it doesn’t say whether this works the same for everyone or only for people who start with high cholesterol.
