Watermelon is another valuable safeguard against high blood pressure. It was proved in recent experiments that a substance extracted from watermelon seeds has a definite action in dilating the blood vessels, which results in lowering the blood pressure. A side-benefit of eating watermelon is its generous supply of the phytochemical lycopene. This pigment in red and pink fruit and vegetables can deter various cancers in women and prostate problems in men. It is also helpful in avoiding the problems of aging in the health of the eyes.
