Objectives This study examined the influence of nutrition on the severity of menstrual pains and associated transient changes in blood pressure (BP) and vascular-health indicators. It has also investigated the influence of nutrition on angiotensin (ANG II) and vascular cell adhesion molecules (VCAM-1). Methods A total of 207 university students, aged between 18 and 25 years, were grouped into three groups: a no-dysmenorrhoea (control) group, a moderate dysmenorrhoea (MDys) group, and a severe dysmenorrhoea (SDys) group, using the NRS-11 scale and initial contactin-1 (CNTN-1) levels. The groups were separately fed vegetable, protein, and carbohydrate meals. The meal plan involved three different types of food served three times a day (for breakfast, lunch, and dinner), beginning 48 h before menstruation. Results We found that 73.9% and 100% of the MDys patients on the protein and carbohydrate diets, respectively, had severe dysmenorrhoea. As many as 69.6% of the SDys patients on vegetable diets experienced no dysmenorrhoea; the BP of 61% of SDys normalised to the standard values of 120/80. The BP of 87% MDys had systolic BP ≥ 130 and ≥90 diastolic BP after carbohydrate meals. On the other hand, 30% of SDys had higher BP after protein meals. With respect to the choice of food, the severity of menstrual pain was positively correlated with ANG II (r = 0.5158) and VCAM-1 (r = 0.5849). ANG-II. Similarly, VCAM-1 were significantly elevated (p < 0.05) in the dysmenorrhoeal participants. The mean VCAM-1 and ANG-II levels of dysmenorrhoeal participants placed on vegetable meals were comparable to the control baseline levels. Conclusions This study recommends the intake of a vegetable meal at least 48 h before menstruation as an effective nutritional approach to preventing and managing severe menstrual cramps. This approach can also prevent associated vascular changes. Carbohydrate meals should be avoided at least 48 h before menstruation.
