Admittedly my google skills are fairly lame but I can't find a single study saying there is a strong link.

So I guess it either doesn't exist or is just not reproducible in a double blind test (i.e. it is probably caused by god when the heathen scientists aren't looking).

Randomly came across the study I had been thinking of:

thirty-five 5- to 7-year-old boys reported by their mothers to be behaviorally "sugar sensitive,"
...
mothers were told their children had received a large dose of sugar, whereas in the control condition mothers were told their sons received a placebo; all children actually received the placebo
...
Mothers in the sugar expectancy condition rated their children as significantly more hyperactive. Behavioral observations revealed these mothers exercised more control by maintaining physical closeness, as well as showing trends to criticize, look at, and talk to their sons more than did control mothers
