Summary

This study aims to investigate the effects of the seed-cycling intervention on premenstrual symptoms and nutritional status. At the beginning of the study, written informed consent will be obtained from all individuals who agree to participate.

During the month prior to the intervention, participants' menstrual cycles will be monitored to determine their menstrual phases. In this period, dietary intake records and menstrual symptoms will be documented, and the estimated ovulation date will be determined based on reported symptoms.

After identifying the participants' follicular phase (approximately days 1-14) and luteal phase (approximately days 15-28), the intervention will be implemented for three consecutive months. Participants will be instructed to consume flaxseed and pumpkin seeds daily during the follicular phase, and sesame seeds and sunflower seeds daily during the luteal phase.

The oilseeds to be consumed will be provided to the participants at the beginning of each month in vacuum-sealed single-use packages.

Seed consumption

After identifying the participants' follicular phase (approximately days 1-14) and luteal phase (approximately days 15-28), they will consume specific seeds daily for three consecutive months. During the follicular phase, participants will consume flaxseed and pumpkin seeds per day. During the luteal phase, they will consume sesame seeds and sunflower seeds per day.
