Regulating of the cardiac rhythm, magnesium probably has a protective effect of the arteries. He would contribute to warn the factors of risk essentials of the cardiovascular illnesses. The cardiovascular illnesses represent the 2nd reason of mortality in France after the cancers. They are characterized by the athérosclérose, a very progressive change of the coronary arteries (the blood vessels that irrigate the heart), with deposits of cholesterol that plug them little by little, coupled to phenomena of oxidization and inflammation. in the beginning, one speaks of chest angina. When forms itself a clot of blood (thrombosis) that comes to obstruct an artery completely, and that a part of the heart cannot receive an oxygen anymore, one speaks of coronary thrombosis. The big factors of risk of the cardiovascular illnesses are perfectly identified: genetic, hypercholesterolemia, tobacco addiction, arterial hypertension, diabetes, overweight and obesity, sedentary lifestyle. He seems also that a deficit in magnesium can contribute to a cardiovascular dysfunction. ..The good magnesium for the heart and the arteries It makes more than twenty years that the researchers observe some ties between some illnesses and some life styles. Among the identified factors, he/it appears that smallest consumers of magnesium (or those of which the magnésémie - blood rate of magnesium - is the lowest) have more risks to develop an illness cardiovasculaire1. The tie between lack of magnesium and cerebral vascular accidents remained the object of critiques. It is not necessary to forget that the magnesium, that is indispensable to the neuro-muscular transmission, participate in the regulation of the cardiac rhythm. One uses it besides in intravenous drip to take care of some people enduring unrest of the cardiac rhythm. To the level of the arteries, the lack of magnesium would encourage a stress oxydatif, responsible of a change of the cells endothéliales (of the partition of the blood vessels) by premature ageing. The deficit in magnesium would also have a tie with the inflammatory phenomena observed in the athérosclérose. Other works also join the weak consumption of magnesium with more elevated blood rates of Protein C Réactive (PCR), a good scorer of the inflammation joined to the risk cardiovasculaire2,3. ..Magnesium, hypertension and diabetes Magnesium, hypertension and diabetes Of the epidemiological studies at the man and works among the rat suggest that an insufficient contribution in magnesium can contribute to the development of an arterial hypertension. The lack of magnesium would increase the effect hypertenseur of salt, and would encourage the vasoconstriction (constriction of the blood vessels). A meta-analysis, compilation of 20 studies regrouping 1 220 volunteers showed a very light reduction of the arterial tension, for a middle supplémentation of 365 mg of magnesium by jour4. Otherwise, a deficit in magnesium could also lead an insulinorésistance, a lack of efficiency of the insulin to reduce the blood sugar (rate of glucose or blood sugar), that would drive little by little to the diabetes of type 2. Finally, some recent studies underline the tie more globally, between insufficient contribution in magnesium and development of a metabolic syndrome: association of several factors of risk of the cardiovascular illnesses, hypertension, diabetes, hypertriglycéridémie (too many triglycérides in blood), good cholesterol (HDL) too low, obésité5. ..To make the full of magnesium to protect her heart From what deficit in magnesium one deludes her cardiovascular risk? The numbers descended of the studies are variable. In one, one leads unrests of the cardiac rhythm while limiting during some weeks the contribution to 100 mg. In another, one nearly observes 2 times more of cardiovascular unrests at people consuming between 50 and 185 mg of magnesium compared to those of whose contribution is consisted between 340 and 1 183 mg. What is certain, it is that the French consume less magnesium than the counseled contribution, 360 mg per day for the women, 420 mg for the men. And that the nutritionists consider that a deficiency can get settled when the contribution is lower to the 2/3 of the contribution counseled, either 240 mg for the women, 280 mg for the men. One has interest therefore to put often to the menu food or drinks particularly rich in magnesium as: .The mollusks: periwinkles, bulots, molds,: until 300 mg for 100 g; .The oleaginous dry fruits: walnut, almonds, pistachios, hazelnuts,: until 250 mg for 100 g; .The dry vegetables: white beans, kidney beans,: until 50 mg for 100 g; .The complete bread: 70 mg for 100 g; Some mineral waters: Hépar, 119 mg by liter, Contrex, 84 mg by liter. .The fruits and fresh vegetables complete the contribution. However, in cardiovascular prevention, to make the full of magnesium is not sufficient. The physical activity and of other dietary measures, are incontournables6: .To reduce her consumption of saturated greases: butter, cream, cheeses, butcher's shops, Viennese breads,.
.To prefer the greases insaturées: to cook with varied oils, colza, walnut, soy, olive,.
.To eat fish at least 2 times per week;
.To make the beautiful part to the fruits and vegetables (5 per day), and to food complete céréaliers; .Not too to salt, to curb the alcohol, to supervise her weight.
