This claim falsely assumes childless people will have successfully developed enough intimate and reliable relationships by the time they are on their deathbed.Research shows establishing “fictive kin” at any age is challenging and nearly impossible when the elderly show signs of dementia or Alzheimer's.
I think the problem with most vegan dishes in the west is the lack of a cultural context. Unlike food conglomerates, cultures give an unbiased generational assessment of what it means to have flavor and health benefits e.g - vegan burger in america (processed as hell) < vegan dumplings (fresh leeks, vegetables, garlic). Also as a woman you do face low iron levels naturally and vegan diets affect how we menstruate.
