Diet and lifestyle have a major impact on your hormones and levels of inflammation all of which can in turn affect your period and menstrual pain. Most people blame their hormones directly for their period problems, but in reality, following an anti-inflammatory diet can be just as effective as taking ibuprofen (Motrin) or paracetamol (Advil). In fact, several studies have shown that an anti-inflammatory diet can be very effective at reducing menstrual and endometriosis pain.
