The French Paradox. The French eat a diet much higher in saturated fats than Americans. Yet the French are less likely than Americans to die of coronary heart disease. This has been termed the "French Paradox." Initial research into this phenomenon has shown the antioxidants (flavonoids) contained in red wine inhibits the oxidation of LDL cholesterol, interrupting the first step of atherogenesis. More recent studies have shown ashitaba antioxidant (chalcone) to be more potent than those in red wine and green tea.
Ashitaba is beneficial to the heart due to the antioxidants(chalcones) it contains. Ashitaba purifies the blood which lowers blood pressure. This is aided by its diuretic qualities. As we get older the blood gets sticky and dirty due to the toxins. Purifying the blood lets the blood flow more easily thus lowering the blood pressure. The

"Flavonoids are scavengers of free radicals...It is possible that quercetin and other flavonoids reduce the rate of formation of oxidised LDL and thus inhibit the growth of atherosclerotic plaques." Hertog and Feskins wrote in Lancet (Oct. 23,1993;342:1007-11).
