About Magnesium

Tuesday, May 31st, 2011

Most of us are deficient in magnesium.

While this macro-mineral is easily obtained from many foods, magnesium deficiencies are extremely common for many Americans. Alcohol consumption, the presence of fluoride, and the consumption of certain foods either increase our need for magnesium, or decrease its absorption. Magnesium is not only one of the key nutrients required in both calcium utilization and protein synthesis, but it also plays a tremendous role in virtually every enzymatic reaction in our body.

Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission and bone mineralization. It is required cofactor for an estimated 300 enzymes. Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis and glucose metabolism.

Essential for:

  • Nervous System Support
  • Energy Production
  • Enzyme Function
  • Bone health
  • Sleep and calmness
  • Decalcification
  • Regular bowel movement
  • Muscles and leg cramps

Quote:

Magnesium ions are essential to the basic nucleic acid chemistry of life, and 80 percent of the enzymes in the body need Mg in order to function. Mg deficiency can affect every organ system in the body. In skeletal muscles, Mg deficiency causes twitches, cramps, back aches, neck pain, tension headaches. With the heart Mg deficiency can cause angina (from spasm of the coronary arteries), high blood pressure, and rhythm disturbances, including sudden death.

Weston Price – That a Clean Tooth Does Not Decay and that Mouth Cleanliness Affords the Best Known Protection Against Dental Caries

Sunday, December 12th, 2010

This article is posted here for “preservation” and archival reasons, sometimes you come across information online that you want to make sure others read, but the internet world is ever-changing, something maybe available today and gone tomorrow, thus I sometimes re-post articles like the one below here but take NO CREDIT for any of them.

Here is the article:

Weston Price – That a Clean Tooth Does Not Decay and that Mouth Cleanliness Affords the Best Known Protection Against Dental Caries.

Dental Cosmos Page 871 1934: by Weston A Price, DDS:

Oral cleanliness is not the best known means for the control of dental caries because:

(I) Since primitive man has had high immunity to dental caries he becomes our control in the great experiment of civilizations.

It is essential there fore, that we study the controlling factors of his environment, of which he is the product, and use these as our yardstick for studying modern civilization.

For this I have studied remnants of several primitive racial stocks where their physical isolation had sheltered them from the influences of our modern civilization, and by studying them and their foods and their methods of living, certain underlying factors are found to be common to all these primitive groups, even though they were living in different countries and on very different foods. This permits us to critically analyze modern civilizations at their points of contact with the primitives and, by studying them and their problems with the standards of immune primitives, not the factors which are contributing to dental caries.

By studying the children in four isolated valley in Switzerland; Loetschental, Visperterminen, Grachen, and Ayer in the Swiss Alps, I found the incidence of dental caries to be only 4.6 percent of the teeth studied. Here oral prophylaxis and modern equipment for practicing it were largely unknown. At St. Moritz, however, at approximately the same altitude, which is highly modernized community with excellent training in oral prophylaxis, the incidence of caries was 29.8 per cent of teeth studied.

At Vissoie and Zinal, which were partially modernized, 22 percent of the teeth examined had been attacked by dental caries. At Herisau, in the plains country of Switzerland, also a highly modernized community with splendid instruction and equipment for mouth cleanliness, the incidence of cares was 24.7 per cent of the teeth examined.

Salt, Tea and Blood Pressure in Pastoral Nomads from Phala Tibet

Monday, August 2nd, 2010

These are a few quotes, resources I used in my research relating to the Tibetan Pastoral Nomads and their diet.

Title: Anthropological Fieldwork in Tibet Studying Nomadic Pastoralists on the Changtang
By: Melvyn C. Goldstein and Cynthia M. Beall (Case Western Reserve University)

Quote:

For example, the nomad diet is exclusively animal products and grain, i.e., they consume no vegetables or fruits, yet they show no obvious signs of vitamin or mineral deficiency. And despite the fact that they consume large Quantities of fat and salt from the Tibetan tea (made with butter and salt) they drink throughout the day and from their heavy consumption of meat, cheese and yogurt, they also have low blood pressure–we found no cases of hypertension.

Read the full paper free here: http://digitalcommons.macalester.edu/cgi/viewcontent.cgi?article=1148&context=himalaya

Another quote, this one is from findarticles.com

The high consumption of salt and animal fat does nottranslate into high blood pressure, at least among Tibetan nomads studied last summer by anthropologist Cynthia M. Beall of Case Western Reserve University. Beall, who is working with Goldstein in Tibet, found no cases of hypertension among more than 120 Phala nomads. The average blood pressure of those measured so far is below reported averages for men and women in the United States. The nomads’ diet consists of meat, dairy products, barley flour and tea flavored with salt and butter; fresh fruits and vegetables are scarce at the 3-mile-high elevation. Beall now plans to measure the amount of salt consumed by nomads. Several factors, including extreme altitude, may help to depress blood pressure, she suggests.

Beall uncovered another surprising finding after takingblood samples from 110 Phala men and women and calculating their hemoglobin concentration–a measure that usually increases at high altitudes. Hemoglobin concentration was greater for Phala nomads than for sea-level populations or for Tibetans living at 12,000 feet above sea level, but residents of Chile’s Andes Mountains have the highest known hemoglobin rates at elevations several thousand feet lower than the Tibetan plateau. A larger sample of Phala nomads will be studied for hemoglobin concentration as well as for other measures of oxygen delivery in the body, says Beall.

Does sodium play an adverse role in hypertension?

Singh RB, Singh NK, Mody R, Cameron EA.

Medical Hospital and Research Centre, Moradabad.

Abstract

It is clear that salt is known to be a health hazard from the ancient times. Sodium intake, which was minimal during evolution, increased significantly with the civilization. The rise in prevalence of hypertension in populations with increased consumption of salt suggested a casual relationship. However, several of these studies showed conflicting results.

Many investigators agree that salt-sensitive persons often have a family history of hypertension. Such individuals possess a sodium transport inhibitor in the arterial smooth muscle cells, which affects their sodium handling (as compared to other persons).

However, many of the putative defects related to sodium can be dissociated from blood pressure and sodium consumption status. It is possible that calcium defects of deficiency of potassium and magnesium follow hypertension and sodium status. For example, the pressure response to sodium chloride may be dissociated from sodium, which may be secondary to adverse effects of chloride on calcium homeostasis. Clinical studies also indicate that the role of sodium is controversial in hypertension.

Sodium restriction can benefit salt-sensitive persons and might not otherwise. However, most authorities believe that moderation of salt intake to a relevant extent is justifiable.

Hypertension induction in Dahl rats.

Flowers SW, Jamal IA, Bogden J, Thanki K, Ballester H.

University of Medicine and Dentistry of New Jersey, Maplewood.

Abstract

There is experimental and epidemiologic evidence that some minerals and trace elements play a role in hypertension. We designed an experiment in which salt and water sources were manipulated to examine the possible impact of this relationship. A strain of rats (Dahl rats) known to become hypertensive with sodium chloride ingestion was used to study the effect of salt source and water source on the induction of hypertension.

The group on tap water and table salt had blood pressures (184 mmHg +/- 19) significantly higher than every other group in the experiment. The experimental animals receiving tap water plus table salt had the highest blood pressure levels, although they consumed the lowest quantity of sodium.

Analysis of the tap water samples showed “soft water” by analysis of calcium and magnesium concentration. This could adversely affect blood pressure.

The relatively high magnesium concentration in sun evaporated sea salt may play a protective role in hypertension induction. The zinc and copper present in tap water may play an exacerbating role.

Magnesium transport in hypertension.

Sontia B, Touyz RM.

Kidney Research Centre, University of Ottawa, Ottawa Health Research Institute, 451 Smyth Rd, #2513, K1H 8M5 Ottawa, ON, Canada.

Abstract

Epidemiological, clinical and experimental evidence indicates an inverse association between Mg(2+) levels (serum and tissue) and blood pressure. Magnesium may influence blood pressure by modulating vascular tone and structure through its effects on numerous biochemical reactions that control vascular contraction/dilation, growth/apoptosis, differentiation and inflammation. Magnesium acts as a calcium channel antagonist, it stimulates production of vasodilator prostacyclins and nitric oxide and it alters vascular responses to vasoactive agonists. Mammalian cells regulate Mg(2+) concentration through specialized influx and efflux transport systems that have only recently been characterized. Magnesium efflux occurs via Na(2+)-dependent and Na(2+)-independent pathways. Mg(2+) influx is controlled by recently cloned transporters including Mrs2p, SLC41A1, SLC41A1, ACDP2, MagT1, TRPM6 and TRPM7. Alterations in some of these systems may contribute to hypomagnesemia and intracellular Mg(2+) deficiency in hypertension. In particular increased Mg(2+) efflux through altered regulation of the vascular Na(+)/Mg(2+) exchanger and decreased Mg(2+) influx due to defective vascular and renal TRPM6/7 expression/activity may be important. This review discusses the role of Mg(2+) in vascular biology and implications in hypertension and focuses on the putative transport systems that control vascular magnesium homeostasis. Much research is still needed to clarify the exact mechanisms of Mg(2+) regulation in the cardiovascular system and the implications of aberrant transcellular Mg(2+) transport in the pathogenesis of cardiovascular disease.
