Does what you eat affect your menstrual cycle and PMS symptoms?

This study looked at the link between diet and the menstrual cycle and found a connection, but it does not give a clear, measurable answer to how strong that link is.

Early or limited evidence Women studied in relation to diet and menstrual cycle regularity

What they did

This was an observational study that looked at how a woman's need for different nutrients changes across the stages of her menstrual cycle, and how this relates to having regular periods and fewer PMS symptoms.

What they found

The study found that the body's nutrient needs shift at different points in the cycle, and that matching diet to these needs is tied to more regular periods and milder PMS symptoms. No specific numbers, percentages, or sample size are given.

What it means for you

Eating a balanced diet that fits your body's changing needs across the month may help support regular periods and ease PMS, but this study cannot say how big that effect is. It does not describe its sample size, location, or method in detail, so the findings should be treated as a general pointer rather than solid proof.
