Korea's "time of the month" remedy

I came to work today and it was, well, "that time of the month" for me so I went to the nurse for some pain relievers to help with cramps.  She gave me two Women's Tyenol and then gave me some little advice on what to eat and not to eat (according to what Koreans believe is best).  Her advice was: don't eat any fruit, don't eat any cold food, and eat only warm food.  Apparently the belief is that if you keep your body warm then it will help keep you more balanced and reduce any potential symptoms that will surface.
