Green foods are some of the lowest-calorie, lowest-sugar, and most nutrient-rich foods on the planet. While green foods comprise a wide variety of different types, from single celled algae to flowering plants, they all share one thing in common, chlorophyll. It is Chlorophyll which produces the green color in plants and is considerd the "blood" of plants.

Chlorophyll's molecular structure is similar to the hemoglobain of human blood. Hemoglobin is our body's oxygen transporter. From a chemical standpoint, the components of chlorophyll are almost identical to those of hemoglobin. A German chemist, Dr Richard Wilsstatter, determined in 1913 that the two molecules closely resemble on another. He found that hemoglobin is composed of four elements - carbon, hydrogen, oxygen and nitrogen - organized around a single atom of iron. Hemoglobin's iron content is the main reason we need a dietary supply of that mineral. Chlorophyll has the same elements, however they are organized around a single atom of magnesium.

The benefits of various green foods seem related to their chlorophyll content. Chlorophyll has the power to regenerate our bodies at the molecular and cellular level. It is known to help cleanse the body, fight infection, help heal wounds, and promote the health of the circulatory, digestive, immune, and detoxification systems. Chlorophyll consumption increases the number of red blood cells and, therefore, increase oxygen utilization by the body. Chloropyll also reduces the binding of carcinogens to DNA in the liver and other organs. It also breaks down calcium oxalate stones for elimination, which are created by the body for the purpose of neutralizing and disposing of excess acid.

Two of the best sourcces of chlorophyll are wheat grass and barley grass. Grass - this humble plant that we walk on, mow and usually take for granted is an amazing doorway to health. It is no coincidence that some of the strongest animals in the world such as gorilias, elephants and cows all eat grass and leaves as the main staple of their diets.
