Absolutely food, or at most a hormonal change based on food. Possibly with s side-order of lack of a few of the childhood diseases that have been controlled with inoculations. 30 years is WAY too small a timeframe for human evolution. That works on the order of 50-100 generations, not a single generation.

If something greatly changed how we select partners the past 100 years it could have an effect within a single generation generation. What could that be? Well, maybe feminism so women don't need to rely on a man to provide income, maybe socialist policies so nobody has to go hungry, and so on, plenty of reasons why some genes could be selected out of the gene pool that was previously fine there.
