How does drinking water support a healthy heart?

Fluid intake may help support heart health, by affecting factors such as the thickness of blood and plasma. In fact, a study in the American Journal of Epidemiology found that subjects who drink five or more glasses of water per day have half the risk of fatal coronary heart disease compared with those who drink less than two glasses of water each day. A diet that is rich in fruits and vegetables provides additional hydration help, as produce can provide roughly 20 percent of your water needs. Cucumbers, celery, zucchini, tomatoes, watermelon, strawberries, spinach, grapefruit and broccoli are all more than 90 percent water.
