I wouldn't mind living off of just this + greens + water...
"One of the oldest life forms on Earth, spirulina is a blue-green microalgae that helped produce the oxygen in our atmosphere billions of years ago so that other life forms could appear (
http://www.chinese-herbs.org/spirulina/). The original ‘superfood,’ spirulina is so nutrient dense that you could survive on it and water alone.
Hundreds of studies have confirmed spirulina’s powerhouse status. It has 60-70% complete protein, meaning it has all 8 essential amino acids and 10 non-essential ones that support good health (
http://www.naturalnews.com/031635_superfood_spirulina.html). That’s more protein than beef, chicken or soybeans. According to Balch, it contains concentrations of nutrients “unlike any other single grain, herb, or plant.” Some of its other valuable components include: gamma-linolenic acid (GLA), linoleic acid, arachidonic acid, vitamin B12, iron, nucleic acids RNA & DNA, chlorophyll and phycocyanin, which is found only in blue-green algae and has been shown to increase survival rates in mice with liver cancer (Balch).
Spirulina is highly digestible, protects the immune system, aids in mineral absorption and reduces cholesterol. Originally from warm alkaline lakes in Africa and Central and South America, spirulina was consumed by Aborigines of those places (including the Aztecs) for centuries, verifying its safety and healthful effects on the body."
