How do the levels of antioxidants in broccoli sprouts compare to other foods / beverages with antioxidants? What is the ORAC score for broccoli sprouts or SGS?
Neither BPP (nor the scientists at Johns Hopkins) have tested broccoli sprouts or SGS extracts using the ORAC method (Oxygen Radical Absorbance Capacity) because we do not believe that it can properly measure the powerful, persistent and prolonged phase 2 enzyme boosting activity and indirect antioxidant capacity of sulforaphane and its pre-cursor glucosinolate glucoraphanin (SGS). ORAC measures the ability of a substance to quench specific free radicals at a specific single point in time in a laboratory (in vitro) test. However, true antioxidant protection of cells and the body requires that there is continuous and long-term capacity to detoxify damaging oxidants. ORAC does not measure this ability over time and therefore simply does not take into account whether a substance continues to provide activity and protection after this single point. Indeed, ORAC is useful in measuring a direct antioxidant where the neutralizing of free radicals is on a one-to-one basis – where one molecule
