Vitamin C is higher in organic USA oranges


Digging through my files the other day and stumbled across some 2002 research on organic oranges. The American study showed that even though organic oranges were half the size of conventional oranges they had 30% more vitamin C. Yep more vitamin C even though the volume eaten is less.

Now there could be a myriad of reasons for this. The researches stated "we speculate that with conventional oranges farmers use nitrogen fertilisers that cause an uptake of more water, so it sort of dilutes the orange. You get a great big orange but it is full of water and doesn't have as much nutritional value
