Orhan Derman, DO, Professor in the Department of Pediatrics at Ihsan Dogramaci Childrens Hospital at the Hacettepe University School of Medicine, et al., wrote in their 2004 article "Premenstrual Syndrome and Associated Symptoms in Adolescent Girls," published in the European Journal of Obstetrics & Gynecology, that:

“In the group of girls who consumed more than 200 ml of milk, 300 ml yoghurt and more than 50 g of cheese per day, the frequency of PMS was less. The relation between calcium consumption and the symptoms of PMS was also found to be statistically significant. It was found that the girls whose consumption of milk was greater had significantly less abdominal bloating (P ¼ 0.017) and less cramps (P ¼ 0.017), less craving for some foods (P ¼ 0.021) and a lower incidence of increased appetite (P ¼ 0.021)…

Calcium was effective on negative affect, water retention, food cravings and pain. Calcium was not found to be effective during the menstrual or intermenstrual phase of the cycle. Similarly we pointed out that girls with the higher dietary calcium consumption had symptoms of PMS (negative affect, pain and water retention symptoms) to a lesser extent, regardless of additional calcium treatment. However, the only statistically significant relationship was between increased milk consumption of the girls and decreased severity of some symptoms (abdominal bloating and cramps, craving for some foods and increased appetite).”
