Researchers have claimed that watermelon could significantly reduce blood pressure in overweight individuals both at rest and while under stress.Florida State University Associate Professor Arturo Figueroa said that the pressure on the aorta and on the heart decreased after con-suming watermelon extract.Figueroa’s 12-week study focused on 13 mid-dle-aged, obese men and women who also suffered from high blood pressure. To simu-late cold weather conditions, one hand of the subject was dipped into 39 degree water (or 4 degrees Celsius) while Figueroa’s team took their blood pressure and other vital measure-ments.Meanwhile, the group was divided into two. For the first six weeks, one group was given four grams of the amino acid L-citrulline and two grams of L-arginine per day, both from watermelon extract. The other group was given a placebo for 6 weeks.Then, they switched for the second six weeks.The results showed that consuming water-melon had a positive impact on aortic blood pressure and other vascular parameters.Notably, study participants showed improve-ments in blood pressure and cardiac stress while both at rest and while they were ex-posed to the cold water.The study has been published in the Ameri-can Journal of Hypertension.
