Is there a nutritional connection to preeclampsia? That idea seems plausible at first, as when the blood samples of women have been analyzed, some researchers have found altered levels of various vitamins and minerals. Furthermore, preeclamptic women have altered patterns of weight gain during pregnancy; and obese women are more likely to develop preeclampsia.
Such considerations may lead one to speculate that certain diets may prevent or reverse the disease, in which case the appropriate diet becomes a therapeutic intervention. However the best research to date suggests this just isn't so.
