Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The participants with dysmenorrhea will be divided into two groups, the assignment will be random to the intervention group with strawberry intake for a month and comparing its effect with de control group. The results of the evaluations carried out prior, to the month and 2 months of the intervention will be compared.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The methods that women use to relieve dysmenorrhea are usually pharmacological, with NSAIDs (Non Steroidal Anti-Inflammatory Drugs) and hormonal contraceptives, but these are not free of adverse effects, so more and more studies are investigating non-pharmacological methods to relieve pain. Menstrual distress is also being included as an object of study.
A healthy lifestyle has been shown to be beneficial in relieving primary dysmenorrhoea. In particular, exercise and eating at least 2 pieces of fruit per day have been identified as protective habits.
Most of the studies that evaluate food intake in women with dysmenorrhea are observational and the few clinical trials that exist are with small samples. Strawberries are rich in flavonoids and phenolic acids, giving them anti-inflammatory and antioxidant properties. Studies carried out with strawberries have shown their benefits against chronic inflammatory and cardiovascular diseases. For these reasons, it is necessary a clinical trial to evaluate the benefits of strawberry in relieving dysmenorrhea and menstrual distress.
Carrying out a clinical trial with strawberries is a challenge. Firstly, there is no consensus on the optimal dose that should be ingested to influence health biomarkers. On the other hand, the use of fresh strawberries involves a significant cost, in addition to the fact that it is a seasonal fruit, which is why the most of trials with strawberries are carried out with freeze-dried strawberry powder.
The aim of this study is to analyze the benefits of strawberry consumption in relieving menstrual pain using the VAS (Visual Analogue Scale) scale and menstrual distress using the MEDI-Q scale, previously validated in Spanish in a previous phase of the study in female university students. The results obtained will be compared between the intervention group belonging to the intake of strawberry (specifically the "Fortuna" variety) and with a control group that will continue with their usual diet during the same period of time. They will be evaluated previously, one month and two months after receiving the intervention. The project has been approved by the Andalusian Ethics and Research Committee.
For the design of the clinical trial, previous studies on food intake and dysmenorrhea, as well as studies on the health benefits of strawberries, have been taken into account.
The "Fortuna" strawberry variety will be provided by the association Fres Huelva and must be eaten daily for a month. Participants will be provided with a menstrual diary in order to avoid forgetfulness bias. Participants who are part of the intervention group will be invited to participate in focus groups in order to know about their experiences during the trial.
Our hypothesis is that women who regularly consume strawberries in their diet will improve their pain intensity and levels of menstrual distress, as well as other symptoms associated with dysmenorrhea.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control group
Participants in the comparison group will not have intervention and will not receive strawberry supplements, they will follow their conventional treatment and their usual diet. They will be evaluated before the start of the intervention, one month and two months after the intervention.
No interventions assigned to this group
Strawberry intervention with Fortuna variety
This group will receive an intake of strawberries of the Fortuna variety. The participants of this group will have to eat 250 g of this strawberry variety per day for 1 month.
All participants in the intervention group will be invited to participate in focus groups once the intervention has ended, in order to learn about their experiences during it.
They will be evaluated before the start of the intervention, one month and two months after the intervention.
Strawberry Intervention
This is an intervention based on the intake of strawberry, specifically the "Fortuna" variety. This intervention is based on the intake of 250 g of fresh strawberries per day for a month. The amount and duration of strawberry intake has been consulted in other studies carried out with strawberries.
