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).

(NaturalNews) The vegetable known as the beetroot in Great Britain (and usually called the table beet, garden beet, red beet or just plain beet in the U.S.) has been studied in recent years for its health-building properties. For example, scientists have found it is rich in the nutrient betaine, which reduces the blood concentration of homocycsteine, a substance linked to heart disease and stroke. Now a study just published in the American Heart Association's Hypertension journal concludes drinking beet juice lowers high blood pressure quickly and effectively -- and could be a natural approach to helping prevent cardiovascular problems.
