NASA studied spirulina as a potential food source for long space missions in the 1970s and 1980s because of its extraordinary nutritional density. It is approximately 60-70% protein by dry weight — higher than beef by weight. Spirulina has been consumed by humans for thousands of years — the Aztecs harvested it from Lake Texcoco as a food source called tecuitlatl.
