Spirulina – the research and some tasty recipes!

The popularity of spirulina stems from the fact that it contains over 100 kinds of nutrients. It is described to be the most complete food source ever!

The WHO (World Health Organisation) has called it one of the greatest super foods on earth and New Agers all over the world are rediscovering the wonders of spirulina. Here we will take a look at some of the research on spirulina and what makes this food so remarkable.

Spirulina is a potent, nutrient dense super food that is derived from a single-celled blue-green alga grown in temperate waters around the world. Spirulina boasts a high content of GLA[i][ii], chlorophyll and contains minerals such as calcium, magnesium potassium and zinc[iii]. Spirulina possesses the highest quantity of protein (65%) of any natural food, far superior to animal flesh which contains 15-25%[iv].

 What are antioxidants?

Antioxidants help us to protect ourselves from harmful free radicals that we encounter and produce daily. They accomplish this by quenching them (by donating an electron) and rendering them harmless so they can be expelled.

Spirulina contains beta-carotene, tocopherols, phenolic acids (phycocyanin)4 and chlorophyll, all of which exhibit antioxidant properties[v], though phycocyanin is thought to be the main component responsible for spirulina’s potent antioxidant activity[vi]. Phycocyanin scavenges peroxyl, hydroxyl and alkoxyl radicals (types of free radicals) in vitro (samples of a tissue/cell taken and tested); and may also reduce tumour necrosis factor-alpha and inhibit microsomal lipid peroxidation (oxidation of lipids forming harmful free radicals).

Further studies have shown the potential of spirulina to increase antioxidant enzymes to near normal levels where they have previously been reduced due to toxicity[vii].

Spirulina aids humoral and cellular mechanisms of the immune system[viii]; it achieves this via varied mechanisms, it stimulates the production of beneficial antibodies and cytokines, increases the level of natural killer cells (that attack tumour cells) and increases the activity of macrophages[ix] (a type of white blood cell that ingests foreign material). With these immunological functions being increased, spirulina may help to enhance disease resistance potential.

Mao et al (2005) carried out a study showing allergic patients consuming spirulina can decrease the allergic response. Spirulina accomplishes this by reducing the production of Interleukin-4 (causes B cells to make antibodies and increases the production of T cells) from phytohemagglutinin stimulated peripheral blood mononuclear cells (type of blood cell) by 32%[x].

Spirulina is easily digested, as its cellular wall consists from mucopolysaccharides (no cellulose wall). Spirulina may also aid proliferation of intestinal lactobacilli thereby assisting gastrointestinal function[xi].

Spirulina is rich in iron; iron is involved in ATP synthesis[xii] and required for immune function as part of peroxide-generating enzymes and nitrous oxide-generating enzymes[xiii].

Spirulina boasts antioxidant and immune properties and also makes a great alternative to synthetically manufactured multivitamin supplements.

The quality (organic) and quantity in which you take spirulina will inevitably affect the results you obtain, consuming an amount equivalent to what you wish to address is most advisable. Numerous research trials have used a plethora of dosages in their studies; some trials used 800mg per kg of body weight, others up to 20g a day and everywhere in between depending on the situation. This indicates that a mere consumption of a few tablets would unlikely produce an affect (i.e. at minimum, 5x 1000mg tablets for a 65kg person).


Recipe ideas!

Spirulina energy balls

Ingredients

1 cup ground almonds

1 tbsp Chia seeds

1 cup medjool dates, chopped fine

2 tbsp sultanas

1 tsp Spirulina powder (preferably organic)

2 tbsp Goji Berries

1 tsp lemon rind

1 tsp Agave syrup or honey

1 tbsp desiccated coconut

 

Add nuts into food processor and blend until chunky. Add all ingredients into the same food processor except the coconut. Once it comes away from the sides it is ready to roll into balls (if it doesn’t come away use a little water to form a dough), roll the balls in coconut.

Store in an airtight container. Refrigerate – will last 1 week.

  1. Is that poisness ?!

  2. Hi Karla,

    Thanks for your question.

    You will be pleased to know that spirulina is not poisonous, it is an algae that contains major macronutrients such as protein and fatty acids plus beneficial phytonutrients, like antioxidants. Due to its nutrient breakdown it is often considered a whole food.

    However, there are some people that may be intolerant to spirulina. This is not because it is poisonous, it is more due to their own body and digestive capabilities.

    For anyone that cant use spirulina, barley grass or wheat grass is another great superfood to consider using.

    Cheers
