Barley grass

 Of all the grasses, Barley grass has probably been researched more, due to the efforts of Dr. Yoshihide Hagiwara, President of the Hagiwara Institute of Health in Japan. He found that in barley was the most excellent source of nutrients that the body needs for growth, repair and well-being.

Barley grass contains eighteen amino acids, including the eight essential ones that is, the amino acids that we must get from our diet. Amino acids are the building blocks of proteins, which are the major constituents of every cell and body fluid (except urine and bile) and are thus necessary for the continual cell building, cell regeneration, and energy production that we need for life. An added benefit of the green barley grass leaf proteins is that they are polypeptides-smaller proteins that can be directly absorbed by the blood, where they promote cell metabolism (the chemical changes that we need to live) and neutralize substances that are bad for our health.
The leaves of the cereal grasses provide the nearest thing this planet offers to the perfect food. For reasons of palatability, higher nutrient
Barley juice is much stronger than steroid drugs but has fewer if any side effects.

Contains a multitude of the body's spark plugs, enzymes. (Enzymes are the catalysts for the body's essential chemical reactions and are responsible for our digestive processes, for providing cellular energy, and for antioxidant effects.)

It  has 30 times as much vitamin B1 as in milk, 3.3 times as much vitamin C, and 6.5 times as much carotene as in spinach, 11 times the amount of calcium in cow's milk, nearly five times the iron content of spinach, nearly seven times the vitamin C in oranges, four times the vitamin B1 in whole wheat flour, and 80 micrograms of vitamin B12 per 100 grams of dried barley plant juice.  This analysis was done by the Resource Research Association, Office of Science and Technology, and Japan Food Analysis Center.
