Magnesium In Your Drinking Water? We Doubt It.
This fascinating article discusses how changes in the way we obtain our drinking water have contributed to widespread magnesium deficiency. Historically, when our communities’ water came from rivers and streams, there was naturally a higher mineral content. Today’s local water purification techniques remove not only impurities but the minerals we need. Furthermore, concerned about the health benefits of tap water, many people buy bottled water instead. Often, however, bottled water does not contain much of any magnesium.
“The upshot of all this is that we cannot rely on drinking water to provide adequate magnesium. The recommended dietary allowance (RDA) for magnesium—that is, the amount required to prevent severe deficiency—is 420 mg a day for men and 320 mg a day for women. In cities with the highest magnesium water content, only 30% of the RDA can be obtained by drinking two liters of tap water a day.4 In most cities, only a meager 10-20% of the daily requirement can be obtained. That leaves 70–90% of the daily magnesium requirement that must be obtained from other sources. Since many people’s diets are also low in magnesium, the average American ingests substantially less magnesium than the RDA.”
