From the thousands of foods available on our earth, we singled out the World's Healthiest Foods on the basis of nutrient density. These foods provide you with the highest amount and greatest variety of nutrients for the least number of calories. If you apply this principle to water, you get the most astounding result imaginable! One cup of water has zero calories. One quart of water has zero calories. One gallon of water has zero calories. But what you can get for these zero calories is nothing short of amazing. High-quality, naturally cycled water moves down through the earth into the groundwater. In route, it can pick up a wide variety and significant amount of minerals from the soil. As they "percolate" down through the earth, natural rainwater, water from snow melt, and most other forms of water become mineralized with calcium, magnesium, and a dozen other health-supportive minerals. In our health benefits section, we'll describe how these dissolved minerals give water some fantastic health supportive properties, in addition to the unique role that water plays as the world's only guaranteed disease-preventing liquid.
