Avoid caesars with vitamin D

According to a new study from the Boston University School of Medicine, women who have a deficiency of vitamin D are four times as likely to have a caesarean birth. The authors of the study think that vitamin D deficiency has an effect on muscle strength which may contribute to difficulties giving birth.

"At the turn of the 20th century, women commonly died in childbirth due to 'rachitic pelvis,' " write Anne Merewood, MPH, IBCLC, from Boston University School of Medicine in Massachusetts, and colleagues. "Although rickets virtually disappeared with the discovery of the hormone 'vitamin' D, recent reports suggest vitamin D deficiency is widespread in industrialized nations. Poor muscular performance is an established symptom of vitamin D deficiency, [and] the current US caesarean birth rate is at an all-time high of 30.2%."
