More than two-thirds of all deaths in the United States are directly related to nutritional deficiencies, so it's no surprise that many people are turning to juicing to ensure optimum nutrition and health. The juices from fresh fruits and vegetables provide every nutrient needed for health and longevity, condensing the nutrients from several pounds of produce into a quart of beverage. Ninety percent of the antioxidant action in produce is in the fruit, not the fiber. Juicing removes the fiber from produce, allowing the body to more quickly absorb and assimilate nutrients.
