I know that most Citrus fruits are heathly foods. High vitamin C and other nutritional goodies. I would assume that blood oranges and Cara Cara's would even rate higher the nutritional scale than say a normal orange. The Lycopene in Cara Cara's and the Anthocyanins in blood oranges are both strong antioxidants, giving these varieties a nutritional edge. I'm surprised they aren't marketed more as Super Foods, like Acai Berry, Pomegranite and others. I would also be interested to see how they stack up against other foods enchriched with like antioxidants.

Although oranges are a very healthy food to eat, providing many benefits, and some antioxidants, they are not among the foods listed high in antioxidants, such as pomegranates. or even spinach. A typical orange supplies approximately 750 antioxidants per 100 grams of fruit consumed. The anthocyanins in blood oranges don't add much more.

According to the Linus Pauling Institute, and the European Food Safety Authority, dietary anthocyanins have little, or no direct antioxidant food value, following digestion. They found that "anthocyanins are indeed powerful antioxidants in vitro, but it is unlikely this antioxidant property is conserved after the plant is consumed". - Millet (848-)

Is there any one Citrus fruit that stands above the others for nutritional value?
