Magnesium and stroke


The study below found some significant facts regarding health effects of certain food.  This is an attempt by us to interpret the findings so that it could be implemented in everyday health practices.  It has to be understood that good eating habits are necessary for optimal health and that means that a variety of good foods have to be consumed every day.  We do believe that some food has medicinal value and could be used to help in the prevention and support of treatment in certain illnesses.  However, if it is not part of a good nutritious diet, it might lose its value.    Although we do believe in the power of natural food, we absolutely do not claim to cure any disease through the consumption of specific food.

This study followed healthy men over a course of 24 years, starting in 1986.  Their diets were compared, looking specifically at the consumption of foods rich in magnesium, calcium and potassium as well as the intake of supplements with these three nutrients.  As they got older they were followed for the risk factors (hypertension and high cholesterol) and the development of stroke.  It was found that a diet rich in all three these nutrients, and no single ones, were associated with a reduced risk to suffer from stroke.

This study summarized a total of eight studies, with 8367 stroke cases among 304,551 participants and looked at magnesium intake and the likelihood of the risk of suffering from a stroke.  The researchers found that higher magnesium intake was associated with a reduced risk.

This study looked at the ability to predict left ventricular hypertrophy which is associated with cardiac risk.  They followed 4203 patients for five years and showed low magnesium levels in the blood is an independent indicator of the possibility of developing an enlarged left ventricle over the following years.  This means it is an indicator which, if detected early enough, gives the person enough time to adjust magnesium levels with a balanced diet and or supplementation.
