very interesting! i wonder if there's been evolutionary impacts of this, if hypothetically repeating the same experiment with westerners who have survived on wheat for thousands of years would yield similar yet quantitatively differentiable results i would also argue that there's a hidden selection going on here in the background, once humans pick up a crop they harvest: the crop that can better influence human psychology on a civilization scale so that those humans become better at harvesting more of that crop, would thereby grant the crop more evolutionary success so i think the psychological aspects of EATING the food are actually important to study in this context. ie have people cultivate wheat and eat rice, vise versa and also compare against wheat-cultivating groups that eat wheat, and so on although this does get messy as if there's already been selection on the human side for traits that better cultivate these crops, then the effects might take generations to show in any meaningful kind of study -- in this case cross-cultural comparisons would be more viable
