Eating this special broccoli lowers bad cholesterol but doesn’t change good cholesterol, overall cholesterol, or fat levels in the blood.
Scientific Claim
High glucoraphanin broccoli does not significantly alter plasma HDL cholesterol, total cholesterol, or triglyceride levels in middle-aged adults at moderate cardiovascular risk over a 12-week period.
Original Statement
“There was no significant change in HDL-C, TC or TAG... Likewise, there was no evidence of any effect on HDL-C or TAG [Supporting Information Figs. 2–4].”

Diet rich in high glucoraphanin broccoli reduces plasma LDL cholesterol: Evidence from randomised controlled trials
This study found that eating a special kind of broccoli lowers 'bad' cholesterol (LDL), even though it didn’t change 'good' cholesterol or triglycerides much. So saying it doesn’t affect cholesterol at all is wrong.
