Preeclampsia and reproductive performance in a community of vegans

Studies at "the Farm," a community of spiritually gathered young people in Summertown, Tenn, have shown that it is possible to sustain a normal pregnancy on a vegan diet. The source of dietary protein (ie, animal or vegetable) does not seem to affect birth weight, as long as vegans are health conscious, receive continuous prenatal care, supplement their diets with prenatal vitamins, calcium, and iron, and apply protein-complementing nutritional principles. Preeclampsia may be caused by a relative prostacyclin deficiency in the face of excessive production of thromboxane A2. A vegan diet (one low in arachidonic acid) might provide protection against this condition, especially if the conversion of linoleic acid to arachidonic acid is inhibited by decreased activity of the enzyme delta-6-desaturase. We examined the maternity care records of 775 vegan mothers for symptoms of preeclampsia, and only one case met the clinical criteria. Since preeclampsia in our culture is frequently associated with unrestrained consumption of "fast foods" (foods having high levels of saturated fat) and rapid weight gain, it is possible that a vegan diet could alleviate most, if not all, of the signs and symptoms of preeclampsia.
