Do you get enough vitamin c in your everyday diet?

According to nutrition researchers from Arizona State University the amount of vitamin C in the blood stream is directly related to fat oxidation - the body's ability to use fat as a source of energy.

Researchers put 20 obese men and women on a controlled, four-week, low-fat diet. One group's diet was supplemented with a 500 mg vitamin C capsule, while the other group was given a placebo, identical in appearance to the vitamin. At the beginning of the trial, volunteers with the lowest concentrations of vitamin C were found to have the highest body fat mass and tended not to oxidize fat well. 

After four weeks, the supplemented group had increased serum concentrations of vitamin C of 30 percent, while the placebo group's blood levels decreased by 27 per cent. As vitamin C blood concentrations fell, so did the participants' ability to oxidize fat (an 11 percent reduction).
