SPIRULINA: GREEN ENERGY!
Raise your hand if you don't have a friend who has ever told you about spirulina! Really? In this article we will talk a little about spirulina and its properties, dispelling some mega myths that circulate around this blue-green micro algae!
STORY OF A CYANOBACT
Spirulina ( Arthrospira platensis ) is improperly defined as an algae while more precisely it belongs to the class of cyanobacteria. It is an ancient form of life on our planet that dates back over 3.5 billion years . The name Spirulina derives from the particular spiral shape of these organisms that grow naturally in the warm and alkaline waters of tropical and subtropical areas of the planet. Spirulina is able to photosynthesize thanks to chlorophyll and some pigments called phycobiliproteins . Among these, the most present in spirulina is phycocyanin , a water-soluble substance with antioxidant and immunomodulatory properties.
COMPOSITION OF SPIRULINA
The FAO ( Food and Agriculture Organisation) in 2008 indicated spirulina as the "food of the future" and the reason can be found in the nutritional completeness of its composition. In particular, when we talk about spirulina we must remember its very high percentage of proteins which can reach up to 70% of its weight. Furthermore, these proteins contain all 8 essential amino acids, i.e. those that our body needs to introduce through the diet. For this reason it is an excellent supplement for vegetarians and vegans.
It is also rich in vitamins including Vitamin E, Beta-carotene and all B vitamins (even if B12 is present in a non-absorbable form for humans). Among the minerals present in spirulina we remember iron, calcium, potassium, magnesium, zinc, selenium and manganese.
In addition to these micronutrients, spirulina is rich in essential fatty acids including linoleic acid, gamma linolenic acid, alpha linolenic acid, EPA and DHA.
Fibres, carbohydrates, phycocyanins and chlorophyll complete this very complete pool of nutrients that make spirulina a true superfood !
PROPERTY'
Spirulina has recognized restorative properties, suitable both for those who play sports but also for those with a highly stressful lifestyle. The restorative activity is in fact due to the presence of vitamins, minerals and proteins, important nutrients for overcoming physical tiredness and improving energy metabolism.
Regarding metabolism, spirulina is a supplement capable of improving the lipid profile, reducing triglycerides and LDL cholesterol. Especially in recent years, again with regard to metabolism, spirulina has been commercially presented as slimming. This benefit has not been proven so you will never hear me recommend spirulina for weight loss! In this case it is best to contact a nutritionist and undertake a targeted dietary program.
The presence of omega-3 polyunsaturated fatty acids can promote an anti-platelet and vasodilation action which makes it a good aid for the cardiovascular system. At the same time, however, these properties are the reason why spirulina should not be taken by people being treated with anticoagulants.
Another precious function of spirulina is to help the immune system by improving the formation of cells of the innate immune system (Natural Killer, macrophages, dendritic cells...). Furthermore, since spirulina is also a good prebiotic , this further promotes our immune defenses.
CONSIDERATIONS ON THE USE OF SPIRULINA
Modern nutrition offers the possibility of eating in a complete and conscious way in order to provide the essential substances for our well-being. However, in so-called Western countries there is on the one hand the increasingly widespread tendency to use "junk" food rich in sugars, additives and preservatives. On the other hand, the rhythms imposed by "modern" life increase levels of tiredness and stress, consequently increasing the need for natural supports such as spirulina.
CONTRAINDICATIONS
Spirulina generally has no contraindications for use, however, in some particular cases, it is preferable to contact your doctor to agree on its use. The conditions that require attention are: thyroid problems (iodine is present in some types of spirulina), pregnancy and breastfeeding, pharmacotherapy with anticoagulants as already mentioned and immunosuppressants.
