The American Assoication for Retired Persons (AARP) has endorsed spirulina as the best anti-aging one can consume.
“1. Spirulina (blue-green algae) Spirulina contains not only the antioxidant phycocyanin but also a bundle of protein, plus omega fatty acids. Once a mainstay food of the Aztecs, spirulina additionally works as an ibuprofenlike nonsteroidal anti-inflammatory. Add one teaspoon to one tablespoon of spirulina a day to smoothies or yogurt, or take it in capsule form. Caution: for some people, spirulina can be overstimulating (kind of like too much coffee), so experiment to find the right balance.” http://www.aarpmagazine.org/health/longevity_foods.html
Bob McCauley wrote about spirulina in his best-selling book, Achieving Great Health. Also available in Chinese translation. The Watershed Wellness Center promotes spirulina as a central part of everyone’s diet and as a food that should be used for a protein source, or replacement, for meat, fish eggs and dairy products.
