A study of 607 women in Türkiye aged 18 to 30 found that those who reported eating more ultra-processed foods also reported more severe premenstrual syndrome (PMS) symptoms. The findings were published in Scientific Reports and are based on women recalling symptoms from the week before their period, which means the link is an association, not proof of cause.
Why it matters
For women who experience PMS, diet is a factor that is often overlooked, and this study adds to evidence that everyday eating patterns may be linked to how symptoms feel. It also suggests that how people respond to hunger and cravings, not just what they eat, may play a role, which could shape future approaches to managing PMS.
This was a survey of 607 women in Türkiye, aged 18 to 30, recruited through university networks, social media and referrals, so the sample is not representative of all women. Its design captures a single snapshot of recalled symptoms and eating habits rather than tracking changes over time, which limits conclusions about cause.
The details
Ultra-processed foods are industrially formulated products that typically contain added sugars, fats and additives, and researchers have linked high intake to a range of health concerns. In this study, women who ate these foods more often reported more intense PMS symptoms, and those who were less likely to act on eating urges or to judge their own eating also reported milder symptoms. The link with ultra-processed food remained after accounting for overall diet quality, eating habits, age and menstrual cycle regularity, while closer adherence to a Mediterranean diet showed no clear association in that analysis.
Timeline
Women recalled PMS symptoms from the week before their period when completing the survey.

Health Landscape
Research on PMS has increasingly examined appetite and diet alongside mood and physical symptoms, moving beyond purely hormonal explanations. Studies like this one add to a growing body of work asking whether nutrition and eating behavior are modifiable factors in how severe menstrual-cycle symptoms feel.
If you experience PMS, it may be worth noting how often you eat ultra-processed foods and how you respond to cravings, and discussing these patterns with your doctor. Because this is a single survey of young women, the findings should be seen as a starting point rather than a reason to change your diet on its own.
The takeaway
The strongest signal here is an association between frequent ultra-processed food intake and more severe PMS symptoms among young women in this survey. Keeping a simple record of eating patterns alongside symptoms across a few cycles can give you useful information to bring to a conversation with your physician.
What happens next
Researchers plan to follow women across several menstrual cycles with repeated measurements of eating, cravings and mood, and a future trial may randomly assign participants to different diets to test whether changing eating eases symptoms.
