I suspect that the Flynn effect begins and ends with the improvement to diet, as is the case with height. Though really, society has changed in so many ways in 100 years, that it's impossible to say this or that was responsible, therefore let's replicate it. At any rate, there's a serious upper limit to it.

Flynn points to data from a World War II famine in the occupied Netherlands showing that the famine region had no difference in IQ changes over time from the region that didn't experience famine. The IQ score increase has also occurred in countries that were well nourished to begin with for the most part.
