Dr. Gabriel Cousins, in his book Conscious Eating, says, “Foods containing chlorophyll have long been known to protect against radiation. Generally speaking, all green foods have chlorophyll. From 1959 to 1961, the Chief of the U.S. Army Nutrition Branch in Chicago found that high-chlorophyll foods reduced the effects of radiation on guinea pigs by 50 percent. This includes all chlorophyll foods: cabbage, leafy green vegetables, spirulina, chlorella, wheatgrass, any sprouts, and the blue-green algae from Klamath Lake called Aphanizomenon flos-aquae (AFA). This variety of blue-green algae is an excellent anti-radiation food because of its high cellular immutability and high regenerative energy, as well as its high chlorophyll content. It should be taken in a dose of four capsules (one gram) four times per day for one week before, and several weeks after, radiation exposure.”
