Spirulina restores the body to a state of high energy according to those who use it. The process may be through its high levels of polysaccharides and essential fatty acids. In Healing with Whole Foods, Paul Pitchford writes, "The special form of protein in spirulina benefits those with problems resulting from excessive animal protein, which does not assimilate well and further burdens the body with waste products." If you already have cancer, making a few diet modifications, such as adding spirulinaand restricting meat and cheese, can make all the difference in your recovery, according to Patrick Quillin's Beating Cancer with Nutrition and Joseph B. Marion'sAnti-Aging Manual. This difference can be the deciding factor between life and death. Spirulina is rich in phycocyanin, a pigment with anti-cancer properties. Spirulina is also the highest plant source of gamma-linolenic acid (GLA), a fatty acid which strengthens immunity and inhibits excessive cell division. (Healing With Whole Foods by Paul Pitchford, page 378) Several animal studies have documented the ability of spirulina to arrest the development of cancer progression, reduce risk of cancer initiation, and boost the immune system.
