What is Spirulina?
Spirulina is among the growing numbers of health supplements you can buy online.
But what exactly is spirulina, and what is it for?
It has often been advertised as being a weight loss supplement.
In actual fact it is so much more than that.
In fact, studies seem to suggest that the spirulina is not much cop when it comes to actual weight loss, but has other advantages so wonderful that both NASA and the European Space Agency have proposed spirulina as the primary food to be cultivated for long term space missions.
So complete is spirulina as a foodstuff, and it does so much good to the human body, that scientists reckon it would be perfect for our astronauts in space.
This makes spirulina much more interesting than you previously might have suspected. It's health benefits are amazing, and very few, if any, dietary health supplements can match it.
So what exactly is spirulina?
Spirulina is an algae, a living, growing organism that lives in many fresh and salt water lakes in the world.
It is especially found in alkaline lakes and waterways, where there is a build-up of mineral deposits of carbonate and bicarbonate.
While spirulina is actually it's old name, it has since been re-classified and named as a cyanobacteria, which consists of two types - arthospira platensis and athrospira maxima.
Neither are true algae either. The only relationship they bear to algae is the ability of photosynthesise in water.
The world's largest commercial spirulina plants are located in the US, Thailand, India, Taiwan, China, Pakistan, Burma and Chile where spirulina is grown in what is called open channel raceway ponds that use paddle-wheels to agitate the water.
It is available as health food supplements in powder, flake and tablet form and is used as a food supplement in various agricultural industries including poultry and fish farming.
Arthrospira platensis occurs naturally in tropical and subtropical high pH lakes in Africa, Asia and South America.
Athrospira maxima is found only in Central America.
Historically, spirulina was an important foodstuff of the Aztecs up until the 16th century. It was harvested from Lake Texcoco and turned into cakes.
The Aztecs called it Tecuitlatl, meaning stone's excrement, which makes it sound extremely unappetizing!
In Chad, spirulina has been used as a daily food since the 9th century BC, and is still in use there today where it is made into small cakes known as dihé. It is harvested in Lake Chad and its subsidiaries.
