# Does diet affect PMS severity?

Yes. Women eating a Western-style diet were 2.35 times more likely to have severe PMS than those with a healthy diet. Women eating very little food had up to 3 times higher odds of moderate or severe PMS. However, this does not prove diet causes PMS.

 Moderate study design

609 women aged 18-35 from Central Europe

## What they did

609 women aged 18-35 from Central Europe reported what they ate using a food frequency questionnaire and rated their PMS symptoms. Researchers grouped their eating patterns into three types: healthy, Western-style, and very low food intake.

## What they found

Compared to healthy eating, women following a Western diet were 2.35 times more likely to have severe PMS (95% CI 1.02-5.44). Women with very low food intake were 2.92 times more likely to have moderate PMS (95% CI 1.09-7.84) and 3.01 times more likely to have severe PMS (95% CI 1.14-7.92).

## What it means for you

Eating patterns may be connected to PMS severity, with Western diets and very restricted eating linked to worse symptoms. But this was a snapshot study so we cannot prove diet causes PMS. The link could work the other way, or both could be caused by something else. Controlled studies would be needed to test this.
