Magnesium content of the food supply in the modern-day world.

A large-scale US survey has shown that the dietary magnesium intake tends to be lower than recommended. The suboptimal intake prevalent among US adults is consistent with the pattern observed in other North American and European surveys. Several factors are discussed, including the waterborne magnesium factor, the loss of magnesium during food refining and the magnesium content of vegetarian diets, as well as various metabolic situations, e.g., hypertension, pregnancy, osteoporosis, drug therapy, alcoholism, stress and cardiac trauma. The benefits of magnesium supplementation among those with sub-RDA intakes are illustrated.

Quantifying the role of magnesium in the interrelationship between human mortality/morbidity and water hardness.

An attempt has been made to quantify the effect of waterborne magnesium on human mortality/morbidity, based on epidemiological and clinical observations reported in several regions of the modern-day world. A consistent pattern has emerged, indicative of a global phenomenon, which illustrates the importance of waterborne magnesium in protecting against cardiovascular trauma and other ailments. These findings attest to the inadequate metabolic magnesium status among modern-day humans, especially those who reside in ultra-soft-water localities.

Cardio-protective contribution of hard waters to magnesium in-take.

The reported inverse correlation between water hardness and incidence of cardiac fatalities has led to tentative hypotheses concerning the role of magnesium intake in this phenomenon. The present article reviews the evidence in favor of the magnesium hypothesis, with emphasis on differentiating between diet-derived and water-borne magnesium intake, and their respective cardio-protective potentials.

Some current aspects of environmental fluoride.

This review presents a Total Environment evaluation of current inorganic fluoride intake by human populations. Inorganic fluoride is a persistant bioaccumulator, and the ever-increasing use (and release) of fluoride compounds in the environment should be of long-term concern in population sub-groups who are most susceptible, and therefore, most "at risk". One of these sub-groups consists of people with impaired kidney function, including subjects with nephorphatic diabetes. The diabetes factor is of particular relevance, not only because the incidence of diabetes has increased by 6%/yr during the period 1965-1975, but also because subjects with nephropathic diabetes can exhibit a polydipsia-polyurea syndrome that results in increased intake of fluoride, along with greater-than-normal retention of a given fluoride dosage. People with inadequate dietary intakes (particularly of Ca and/or Vitamin C) are also likely to be more "at risk" as a consequence of low-dose long-term fluoride ingestion. Evidence is presented, showing that there has been an escalation in dialy fluoride intake via the total human food-and-beverage chain, with the likelihood that this escalation will continue in the future. Recent observations, relating to an increasing incidence of chronic fluoride intoxication among humans, is also emphasized.
