Broccoli and cardiovascular disease.

CVD: Data about the relation with total cardiovascular disease was provided by 3 cohorts. No significant association of high vs low consumption was found with CVD risk (21, 36), or mortality (17).

CHD: Data about the relation with coronary heart disease was provided by 2 cohorts. Significant protective effects against CHD death were found in both cohorts. The average RR = 0.57. Since consumption was defined in "frequency" in one cohort (17), and "servings" in the other cohort (10) it was not possible to define the level of consumption for this effect.
No association was found with nonfatal MI (10).

Stroke: Data about the relation with stroke was provided by 1 cohort (17). No association was found with stroke mortality.

Conclusion: Significant protective effects of broccoli against CHD death were found in 2 cohorts of moderate-large size. Both cohorts included women only. Broccoli possibly protects against CHD death among women (- 43%). No level of consumption for this effect could be defined. No evidence was found for an effect with any other end point.
