There was a study a few years back that looked at epigenetic shifts that persist for several generations in the instance of malnourishment of a pregnant mother - I think they were looking at Indian populations from around partition - the upshot was that the offspring was much more likely to be type 2 diabetic, which makes sense from an evolutionary perspective, as if you’re going to be born into a low calorie/famine environment, having elevated blood sugar is eugenic.
