Without the side effects, Naringenin, an antioxidant which gives grapefruit its bitter taste, can do the same job as two separate drugs currently used to manage Type 2 diabetes ★ http://www.dailymail.co.uk/health/article-1306240/Antioxidant-grapefruit-help-treat-diabetes.html ★ The flavanones naringenin and hesperetin exhibit estrogenic, anticarcinogenic and antioxidative properties. Orange juice and grapefruit juice contain high amounts of these compounds, and therefore their intake from the diet can be relatively high. Because of the relatively high concentrations of flavanones in plasma after after ingestion of grapefruit juice, considerable health effects could ensue in individuals consuming them regularly ★ Flavonoid compounds exhibit inhibitory effects against multiple viruses. While naringin was not inhibitory to herpes simplex virus, poliovirus, parainfluenza virus, the other three flavonoids were effective in various ways: Hesperetin reduced intracellular replication of all four viruses; catechin inhibited infectivity but not intracellular replication of RSV and HSV-1; and quercetin was universally effective in reducing infectivity!
