The health benefits of magnesium : role and food sources

The benefits of magnesium on our body

An essential mineral

Magnesium is the 5th most present mineral in our body. It is a cofactor (non-protein chemical that assists with a biological chemical reaction) of more than 300 enzymes (protein catalyzing a biochemical reaction)! It is therefore an essential player in the regulation of several fundamental functions involved in the following health areas:

  • Bone health
  • Tonus & energy production
  • Cardiovascular function
  • Normal functioning of the nervous system

Dietary sources of magnesium

Our body is not able to produce this mineral. We must therefore get it from our food. As can be seen in the following table, seaweed is an excellent source::

 

The other ingredients most known for their richness are:

 

A worldwide magnesium deficiency

Depending on age, the nutritional reference values for magnesium change. This can be seen in the table below:

The World Health Organization estimates that approximately 75% of the world’s population suffers from magnesium deficiency. The main causes of the high prevalence of this deficiency are :

  • A processed diet: in general, “industrial food” lacks many essential elements.
  • Intensive agricultural practices that result in a magnesium deficit in the soil.
  • A stressful lifestyle that causes the body to lose magnesium (the vicious circle theory).
  • Increased needs in certain situations, especially for pregnant women, athletes and the elderly.

The first symptoms associated with a deficiency are the following:

  • Fasciculation (spontaneous and abnormal contraction of part of the muscle bundles of a muscle), in particular eyelid spasm
  • Contractures, cramps, tingling and numbness
  • Insomnia/fatigue
  • Anxiety/irritability/difficulty concentrating
  • Headaches/vertigo/nausea

Thus, a magnesium supplementation is often recommended at certain times of the life and the year to help our organism to fill this deficiency, allowing it to function at its best.
