If you're after an antioxidant, try oranges.AddStyleIf you're in the market for an antioxidant to keep your body young and healthy, new research suggests you'd be much better off with oranges than vitamin C tablets.Although vitamin C is best known for its protection against scurvy and, possibly, the common cold (see 'Vitamin C best in the cold'), fruits rich in vitamin C are also powerful antioxidants that protect cellular DNA from being damaged by oxidation. Going without such foods leads to DNA damage long before the iconic bleeding gums of scurvy are seen.But do vitamin C pills on their own have the same protective effect as fruit? Serena Guarnieri and a team of researchers in the Division of Human Nutrition at the University of Milan, Italy, designed a simple experiment to find out.The team gave test subjects a single glass of blood-orange juice, vitamin-C-fortified water, or sugar water to drink. The blood-orange juice and the fortified water had 150 milligrams of vitamin C each, whereas the sugar water had none. Blood samples were taken from the test subjects 3 hours and 24 hours after their drink. Unsurprisingly, blood plasma vitamin C levels went up after drinking both the juice and the fortified water.The blood samples were then exposed to hydrogen peroxide, a substance known to cause DNA damage through oxidation. The damage was significantly less in the samples taken from volunteers who had ingested orange juice, in both the samples collected 3 hours after consumption and 24 hours after the drink. Unsurprisingly, the sugar water had no protective effect. But neither did the vitamin-C-fortified water...............http://www.nature.com/news/2007/070416/full/070416-15.html

Hello---it says: "The blood samples were then exposed to hydrogen peroxide, a substance known to cause DNA damage through oxidation"--- I thought hydrogen peroxide is supposed to enrich your blood with oxygen and was good for you---can somebody explain?---Any thoughts?
