Postpartum depression(PPD) is a common emotional disorder in the puerperium, which has negative impact on women, infants and family. There is growing evidence that abnormal concentration of a number of nutrients (including polyunsaturated fatty acids, vitamin D and homocysteine) is associated with depression in postpartum population. Further studies on the mechanisms for the functions of nutrients and regulation of nutritional states in the puerperium will be of great value in the prevention, early diagnosis and treatment of PPD.
