It significantly reduces quality of life and impairs daily activities. Strawberry consumption has demonstrated benefits in chronic and inflammatory diseases. Therefore, the aim of this study was to evaluate the effectiveness of consuming fresh strawberries from Huelva on menstrual pain in young female university students with primary dysmenorrhea.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A randomized clinical trial was conducted including 64 participants with PD, who were randomly assigned to either the control (\n                      <jats:italic>n<\/jats:italic>\n                      = 31) or intervention group (\n                      <jats:italic>n<\/jats:italic>\n                      = 33).

The primary outcome was pain intensity assessed using the visual analog scale (VAS). The secondary outcomes included the variables menstrual cycle length, bleeding duration, hours of sleep, absenteeism, perception of health status, State\u2013Trait Anxiety Inventory (STAI) and mental well-being.
