No matter how you slice it, watermelon has a lot going for it sweet, low calorie, high fiber, nutrient rich and now, there's more. Evidence from a pilot study led by food scientists at The Florida State University suggests that watermelon can be an effective natural weapon against prehypertension, a precursor to cardiovascular disease. It is the first investigation of its kind in humans. FSU Assistant Professor Arturo Figueroa and Professor Bahram H. Arjmandi found that when six grams of the amino acid L-citrulline/L-arginine from watermelon extract was administered daily for six weeks, there was improved arterial function and consequently lowered aortic blood pressure in all nine of their prehypertensive subjects (four men and five postmenopausal women, ages 51-57).

NORMAN, Okla.—Consumption of a low-calorie energy drink may improve physiological adaptations to strength training, according to a new study (J Strength Cond Res. 2010;24(8):2227-38. DOI: 10.1519/JSC.0b013e3181aeb0cf). Researchers from the Human Performance Laboratory, Department of Health and Exercise Science at the University of Oklahoma, assessed the effects of daily consumption of an energy drink alone or with exercise on measures of body composition, cardiorespiratory fitness, strength, mood and safety in previously sedentary males. A total of 38 men were recruited for the 10-week study and randomly assigned to energy drink + exercise (EX-A), energy drink (NEX-A), placebo + exercise (EX-B) or placebo (NEX-B). Subjects in the exercise group participated in resistance and endurance exercise.
