Orange juice. Computer artwork of a glass of orange juice seen over an orange sea. Oranges (Citrus sinensis) are a rich source of vitamin C (ascorbic acid). This is needed to build and maintain healthy bones,teeth,gums and blood vessels,and helps some of the body's enzymes to work properly. Unused vitamin C is quickly excreted by the body in urine and regular dietary intakes are needed to prevent ill-health. A person typically consumes about 45 milligrams of vitamin C a day. Lack of vitamin C causes the disease scurvy,where small blood vessels leak blood and the teeth fall out | |
