If I can find it, I'll send it forth. Basically, it's that glucose and 
Vit C compete for the same cellular uptake path. The more glucose in 
your diet, the less Vit C you're getting/the less glucose in your diet, 
the less Vit C you require in your diet. It's not so much that one isn't 
consuming enough C, it's that they're consuming too many foods that 
compete with it for absorption.

There's a much bigger worry:- the fact that animal foods(fats in particular) produce far more heat-created toxins after cooking(such as advanced glycation end products etc.) than any other foods, thus speeding up the incidence of various age-related diseases.

Does this happen in the absence of carbs? Or perhaps: if the body isn't 
overloaded dealing with high insulin levels and other factors, does this 
have much of an effect? Have the effects of AGE's, etc, been tested in 
people NOT eating SAD, etc? Are those age-related diseases correlated 
with AGE's in the diet, or caused by them? What else is a factor? (It's 
already been shown that high levels of insulin are a huge factor in 
various age-related diseases, for instance)
