Why Wheatgrass?
Wheatgrass juice is nature’s finest medicine. It is our signature elixir here at Hippocrates. It is a powerful concentrated liquid nutrient. Two ounces of wheatgrass juice has the nutritional equivalent of five pounds of the best raw organic vegetables. For example, wheatgrass as twice the amount of Vitatin A as carrots and is higher in Vitamin C than oranges! It contains the full spectrum of B vitamins, as well as calcium, phosphorus, magnesium, sodium and potas-sium in a balanced ratio. Wheatgrass is a complete source of protein, supplying all of the essential amino acids, and more. It has about 20% of total calories coming from protein. This protein is in the form of poly peptides, simpler and shorter chains of amino acids that the body uses more efficiently in the blood stream and tissues.
In addition to flooding the body with therapeutic dosages of vitamins, minerals, antioxidants, enzymes, and phytonutrients, wheatgrass is also a powerful detoxifier, especially of the liver and blood. It helps neutralize toxins and environmental pollutants in the body. This is because Wheatgrass contains beneficial enzymes that help protect us from carcinogens, including Superoxide Disumates (SOD), that lessens the effects of radiation and digest toxins in the body. It cleanses the body from head to toe of any heavy metals, pollutants and other toxins that may be stored in the body’s tissues and organs.
