A Danish clinical study has found that, contrary to earlier research, eating broccoli sprouts does not improve cardiovascular performance or lower blood pressure. Forty participants, all of whom had hypertension, either ingested 10 grams daily of dried broccoli sprouts rich in the antioxidant glucosinolate, or continued their normal diet for four weeks. No significant differences in blood pressure or other measurements of cardiovascular health, including cholesterol levels, were found among the participants, even though the glucosinolate dosage of the dried sprouts was twice that used in earlier Japanese research. In that study, scientists had found a decrease in total and LDL cholesterol after only a week of daily ingestion of fresh broccoli sprouts.
