The Effect of Seed Cycling-Based Nutritional Intervention on Premenstrual Symptoms
Evaluation of the Effect of Seed Cycling on Premenstrual Symptoms in Healthy Adults
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.

Assessment of Premenstrual Syndrome Scale at the beginning and End of the Study
Lasso di tempo: The premenstrual weeks of the first and fourth months of the study
|
To evaluate the severity of symptoms experienced during the premenstrual period, the Premenstrual Syndrome Scale, a validated instrument, will be administered during the premenstrual weeks of the first and fourth months. The Premenstrual Syndrome Scale is a self-report measure developed to assess the physical, emotional, and behavioral symptoms experienced by women during the luteal phase of the menstrual cycle. The scale consists of a total of 44 items and comprises nine subdimensions. Each item is rated on a five-point Likert scale. Higher total scores obtained from the scale indicate greater severity of premenstrual symptoms. Subdimension scores may be calculated separately, and an overall assessment can also be conducted based on the total score. |

Assessment of Dietary Diversity Score at the Beginning and End of the Study
Lasso di tempo: At the beginning of the first month and at the end of the fourth month of the study
|
The Dietary Diversity Score is based on the nine food groups recommended by the Food and Agriculture Organization.
According to the scoring system, a score of ≥6 points is classified as high dietary diversity, 4-5 points as moderate dietary diversity, and ≤3 points as low dietary diversity.

Assessment of Composite Dietary Antioxidant Index at the Beginning and End of the Study
Lasso di tempo: At the beginning of the first month and at the end of the fourth month of the study
|
The Composite Dietary Antioxidant Index (CDAI) is a quantitative measure that reflects the overall impact of the major antioxidant nutrients consumed through the diet and is used to assess the total antioxidant capacity of the diet.
This index is considered a reliable indicator as it represents the cumulative effect of dietary antioxidants.The Composite Dietary Antioxidant Index will be calculated based on individuals' 24-hour dietary intake records, by assessing the intake of six antioxidant nutrients: vitamin A, vitamin C, vitamin E, carotenoids, zinc, and selenium.
