Ummmm.....I'm not so sure.

Such "stress" would have to specifically affect the DNA of a person's sperm or egg cells,
not their somatic cells, for inheritance to take place, and even then
inheritance would happen only rarely and randomly
... in a comparatively miniscule number of pregnancies.

When the stress of pregnancies during the severe starvation and war time conditions
at Stalingrad during WWII was investigated for birth defects, the effects could not be shown.

I think UT's emphasis on "culture" is important, not in the food/water sense of "nurture",
but in the overall sense of societal support and traditions.
Unfortunately, some of those traditions are not always beneficial to the individual.
