Several high-profile studies were reviewed such as the prolific Nurses Healthy study, the large-scale Polish study, and a number of Japanese studies. All of which showed bioflavonoids have shown cardioprotective properties through correlations between flavanone intake and a decreased risk of stroke and other cerebrovascular diseases.
