Less severe PMS was noticed in women consuming a diet rich in calcium and vitamin D.
Dr. Elizabeth R. Bertone-Johnson and colleagues at the University of Massachusetts at Amherst conducted the study. They took data from 1,057 women aged 27 to 44 who participated in the Nurse Health Study II and developed PMS during a 10-year period, and 1,968 women who did not develop PMS. This data was analysed and interpreted.
The results revealed that women with the highest vitamin D intake had 40% less likely to have PMS then those with the lowest intake. Calcium intake was also found to be effective in relieving PMS. A 30% difference was found between women with highest calcium intake and lowest intake.
The authors said that high levels of calcium and vitamin D reduced the fluctuation of calcium and vitamin D during menstruation, which causes PMS.
