Does eating soy help with PMS symptoms?
Higher dietary intake of soy isoflavones correlated with fewer menstrual symptoms. The link suggests soy might help, but this study cannot prove soy causes the benefit.
What they did
Cross-sectional study of 84 Korean women aged 28-40 years living in the USA. Researchers measured soy isoflavone intake using a food frequency questionnaire and menstrual symptoms using the Moos Menstrual Distress Questionnaire.
What they found
Soy isoflavone intake was significantly correlated with lower menstrual distress scores in the menstrual phase, suggesting a beneficial effect on symptoms.
What it means for you
This preliminary finding suggests soy isoflavones might help reduce certain menstrual symptoms. However, the study was small and cross-sectional, so it cannot prove soy causes the benefit. Other factors could explain the link. More research is needed.
