From the 1996 FDA Science Forum. They are the units that will be subjected to statistical analysis. Transglutaminase 2 as a novel target in chronic kidney disease - Methods, mechanisms and pharmacological inhibition. Both cases and controls had a mean age of 62.9 years. The deaths excluded were those caused by hypertensive disease (ICD codes 401–405), ischemic heart disease (ICD codes 410 to 414), diseases of pulmonary circulation (ICD codes 415 to 417), other forms of heart disease (ICD codes 420 to 429), cerebrovascular disease (ICD codes 430 to 438), and diseases of the arteries, arterioles, and capillaries (ICD codes 440 to 448). Also fear of hypertension should not deter anyone from drinking water with low magnesium levels. Yes, they are! This is an important finding for the Taiwan water industry and human health. Copyright © 2021 American Journal of Hypertension, Ltd. Water described as "hard" is high in dissolved minerals, specifically calcium and magnesium. Therefore, the decedent's residence, place of birth, and place of death are likely to be listed as the same municipality, although the place of birth information was not available for this data set. Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (such as antacids and laxatives). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Several studies have reported that calcium and magnesium in drinking water have a dose-dependent protective effect when it comes to cardiovascular disease. This inverse association was not statistically significant except for the comparison involving the group whose calcium exposure was in the second highest quintile with the group with the lowest exposure. Because it is mandatory to register death certificates at local household registration offices and as the household registration information is verified annually through a door-to-door survey, the death registration in Taiwan is very complete. This elimination of unsuitable municipalities left 322 municipalities for analysis. In addition, the acidity of the water influences the reabsorption of calcium and magnesium in the renal tubule. The mean magnesium concentration in the drinking water was 10.9 mg/L (SD = 7.6) for the cases, and 11.2 mg/L (SD = 7.5) for the controls. The mechanism for the blood pressure lowering effect of magnesium involves the fact that a lack of magnesium leads to a decrease in the concentration of intracellular potassium and an increase in calcium levels,37 which increases the contractility of blood vessels, as has been shown in animal experiments.38. This report examines whether calcium and magnesium in drinking water are protective against hypertension. The municipality of residence for all cases and controls was identified from the death certificate and was assumed to be the source of the subject's calcium and magnesium exposure via drinking water. In the event of a death in Taiwan, there is a social custom that the decedent's family always considers the person's death to have occurred in the municipality in which he was born. Many studies have demonstrated a negative association between blood pressure and calcium and magnesium levels. By Joseph Cotruvo, PhD, President, Joseph Cotruvo & Associates LLC, Washington, DC USA. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Hard water is not a health risk, but a nuisance because of mineral buildup on fixtures and poor soap and/or detergent performance. A systematic comparison of commercially produced struvite: Quantities, qualities and soil-maize phosphorus availability. Magnesium plays a critical role in brain function and mood, and low … There are products designed to “fortify” such deionized or distilled water with magnesium … Ray Tackaberry, Successor Librarian. Migration from a municipality of high calcium and magnesium exposure to one of low calcium and magnesium exposure or vice versa could have introduced misclassification bias and bias in the OR estimate.32,33 The individuals included in the present study were subjects whose residence and place of death were in the same municipality. The waterworks in each municipality received a questionnaire requesting information on whether any changes had occurred in the water supply or the treatment of the water during the past 20 years. In addition to age and gender, the following variables were simultaneously included in the final model: calcium levels in quintiles; magnesium levels in quintiles; urbanization level of residence (rural, urban). For controls, the most frequent causes of death were diabetes mellitus (11.0%), liver cancer (9.0%), lung cancer (8.4%), chronic liver disease and cirrhosis (8.0%), diseases of the respiratory system (7.9%), and diseases of the genitourinary tract (5.0%). We believe that this ameliorates the migration problem. This may create collinearity in the regression model making it difficult to detect the effect of calcium. © 1999 by the American Journal of Hypertension, Ltd. This study was partly supported by a grant from the National Science Council, Executive Yuan, Taiwan (NSC-87-2314-B-037-074). If your diet typically includes rich sources of calcium and magnesium, then there are likely no risks in drinking water with lower concentrations of these minerals. As was described earlier, hardness is partially caused by magnesium. : 8.Stitt FW, Crawford M, Clayton DGet al. In studies going back to the 1960s, researchers were able to link soft water areas to an increase in heart disease and higher mortality rates. The association between hypertension death with calcium and magnesium levels in drinking water was measured using odds ratios (OR) and their 95% confidence intervals (95% CI) from conditional logistic regression models. Information on magnesium! Not only, calcium and magnesium, but other constituents also affect different health aspects. The urbanization level of each municipality was based on the urban–rural classification scheme of Tzeng and Wu.43. To go directly to a specific category, click on an item in the list below. Adverse Effects. Furthermore, Taiwan is a small island with a convenient communication network, and the accessibility of medical service facilities is comparable among study municipalities. Cases had a higher rate (43.6%) of living in metropolitan municipalities than the controls (37.9%) (Table 1). ORs and their 95% CIs were calculated using the group with the lowest exposure as the reference group.30 Values of P < .05 were considered statistically significant. Start low, e.g., no more than 4 ounces, then build up to 8 ounces 2-3 times per day to obtain the full benefit. All eligible hypertension deaths (2336 cases) of Taiwan residents from 1990 through 1994 were compared with deaths from other causes (2336 controls), and the levels of calcium and magnesium in the drinking water of these residents were determined. loading. DONATIONS/BEQUESTS TO SUPPORT THIS LIBRARY AND FURTHER MAGNESIUM RESEARCH WILL BE GRATEFULLY ACCEPTED. Nonetheless, in the modern-day world, intake of dietary magnesium is often lower than the recommended dietary amount of 6 mg/kg/day.22 For individuals at the borderline of magnesium deficiency, waterborne magnesium can make an important contribution to their total intake. A control group was formed using all other deaths, excluding those deaths that were associated with cardiovascular diseases. Manganese often results in a dense black stain or solid. Such a geographic distribution may suggest an environmental risk factor. Epidemiologic studies have shown that dietary calcium is inversely associated with BP.7–12 Studies conducted in several animal models of hypertension have also been consistent in demonstrating a hypotensive effect of calcium supplementation.13 Magnesium and calcium are the main determinants of water hardness. : 10.Ackley S, Barrett-Connor E, Suarez L: 12.Gruchow HW, Sobocinski KA, Barboriak JJ: 15.Witteman JCM, Willett WC, Stampfer MJet al. Mandibular-related bone metabolism in orchiectomized rats treated with sex hormones. CONTACT: Ray Tackaberry, Successor Librarian, at (408) 897-3023 or email to ray@mgwater.com. These can include calcium, magnesium, manganese, and so on. The significant association between mortality from hypertension and the levels of magnesium in drinking water is supported by knowledge of the functions of magnesium. Hardness (calcium and magnesium) remains reasonably constant for long periods of time and is a quite stable characteristic of a municipality's water supply.29 Some information on the levels of water hardness was available for the study areas in 1980. 1997;19(2):258-72. The increased magnesium group had a 27% to 37% lower risk of death from hypertension. Many of them cover more than one subject. For a reader-friendly overview of Magnesium, see our consumer fact sheet on Magnesium.. Introduction. A guideline for magnesium has therefore not been specified. Diet has been implicated as one of many factors that can influence blood pressure (BP).6 Dietary calcium is the main source of calcium intake. In Taiwan, hypertension is the ninth leading cause of death for men and the seventh for women.1The age-adjusted mortality rate for hypertension was 12.27 per 100,000 among men and 12.34 among women in 1995. In addition, the loss of magnesium from food is lower when the food is cooked in magnesium-rich water.34 Another reason why magnesium in water can play a critical role is its higher bioavailability. In the general population, the major proportion of magnesium intake is through diet, and to a lesser extent via drinking water (in Sweden, generally <5% is from drinking water).21 There is no available data for assessing the percentage that drinking water contributes to the total magnesium intake in the present study. Licensed by the California Department of Health By comparison, in the previous century only about Universal drinking water and beverages containing moderate to high levels of magnesium (10–100 ppm) could potentially prevent 4.5 million heart disease and stroke deaths per year, worldwide. We need to better understand the interrelation of various water and food constituents, as well as individual risk factors, in the pathogenesis of IHD. 7.McCarron D, Morris C, Holly Jet al. Testing drinking water for iron and manganese The quality of water supplied by public water systems is regulated by the U.S. Environmental Protection Agency (EPA.) The samples were then analyzed by the waterworks laboratory office using standard methods. Magnesium Water does not need to be refrigerated, as there is nothing that spoils in the mixture. After adjustment for magnesium levels in drinking water, there was no difference between the groups with different levels of calcium. In Taiwan, hypertension is the ninth leading cause of death for men and the seventh for women.1 The age-adjusted mortality rate for hypertension was 12.27 per 100,000 among men and 12.34 among women in 1995. However, controlling for magnesium levels eliminates the perceived effect of calcium levels on hypertension mortality. The modern processed food diet, low in magnesium and spreading globally, makes this well-researched potential of drinking-water magnesium worth serious consideration, especially in areas where insufficient dietary intake of magnesium is prevalent. Excluded from the analysis were 30 aboriginal townships and 9 islets that had different lifestyles and living environments. Canyon Road, Patterson, CA 95363. Magnesium intake from drinking water was significantly inversely associated with hypertension death risk in a model controlling for age and gender. Of the 2336 cases, 1500 were men and 836 were women. You may be thinking, aren’t these all minerals that are good for our health? For each death, detailed demographic information, including gender, year of birth, year of death, cause of death, place of death (municipality), and residential district (municipality) were recorded on computer tapes. may not be sold. Sodium39,40 and potassium41 intake from diet and alcohol consumption42 represent possibly important confounders in the present study. The number of visitors to this page beginning September 29, 1995 is: Call for papers--previously published or original, Program Announcement, April 24, 2010, Pages 440 through 447 of the Report of the Safe Drinking Water Committee of the National Academy of Sciences, 1977. This figure is only 81.9% of the recommended daily intake.20 The mean calcium concentration in Taiwan's drinking water is 34.7 mg/L. Location: Central California, at 19,000 Del Puerto Canyon Road, Calcium and Magnesium in Drinking-water: Public health significance. Information on the levels of calcium and magnesium in each municipality's treated drinking water supply was obtained from the Water Quality Research Center of the Taiwan Water Supply Corporation27 to whom each waterworks is required to submit drinking water quality data including the levels of calcium and magnesium. Water with a high mineral content, or "hard" water, is also a source of magnesium. Under normal conditions, magnesium levels are carefully regulated, and short-term dietary deficiencies can... Absorption, Distribution and Excretion. It is also unlikely that there would be a direct relationship between other risk factors and the level of magnesium in drinking water. The WHO concluded that the magnesium in drinking water is the mineral in drinking water that’s likely to have the most beneficial effect on heart health. Magnesium links! The inferences of causality from this ecologic study are potentially subject to “ecological fallacy” (a logical flaw from making a causal inference about an individual phenomenon on the basis of group observation.” Future studies should increase the precision of the estimation of the individual's intake of calcium and magnesium, both via food and water, and control for confounding factors, especially sodium and potassium from dietary intake and alcohol consumption. The reason for not finding a protective effect of calcium on risk of hypertension death may be the fact that calcium and magnesium levels in the drinking water are highly correlated (correlation coefficient, 0.65). The Yi People study, Magnesium in drinking water and death from acute myocardial infarction, Recommended dietary amounts of magnesium: Mg RDA, Calcium and magnesium in drinking water and risk of death from cerebrovascular disease, Calcium and magnesium in drinking water and risk of death from colon cancer, Calcium, magnesium, and nitrate in drinking water and gastric cancer mortality, Calcium and magnesium in drinking water and risk of death from rectal cancer, The Statistical Data of Water Quality, Taiwan. Interest concerning the role of calcium and magnesium in human cardiovascular disease was stimulated by ecologic studies that demonstrate… School of Public Health, Kaohsiung Medical College. Health Considerations Essentiality. Although causes of death may be misdiagnosed or misclassified, the problem has been minimized through the improvement in the verification and classification of causes of death in Taiwan since 1972. Marx A(1), Neutra RR. Nonetheless, in the modern world, intake of dietary magnesium is often lower than the recommended dietary amounts of 6 mg/kg/day.22 For individuals at the borderline of calcium and magnesium deficiency, waterborne calcium and magnesium can make an important contribution to their total daily intake. The Role of Mitochondrial Dysfunction in Preeclampsia: Causative Factor or Collateral Damage? Their details have already been described in earlier publications.23,,,26,28 The final complete data consisted of drinking water quality data from 252 municipalities. Is the RDA for Magnesium Too Low? In the first and second editions, these constituted Volume 2 of the GDWQ. In addition, iron and manganese bacteria are not known to present a health risk. : 21.Rubenowitz E, Axelsson G, Rylander R: 35.Theophanides T, Angiboust JF, Polissiou M: 40.Cutler JA, Follmann D, Elliott Pet al.

Consumers can take FREE magnesium rich water at the Free One may hypothesize that waterborne calcium can make an important contribution to the total daily intake for subjects with insufficient calcium intake. per liter. This figure is only 81.9% of the recommended daily intake.20 The major portion of magnesium intake is through diet, and to a lesser extent by drinking water.21 There are no available data for assessing the percentage contribution of drinking water to the total magnesium intake in Taiwan. Data collected included the mean levels of calcium and magnesium for the year 1990. Iron is an essential element in human nutrition, and the health effects of iron in drinking water may include warding off fatigue and anemia. Thus, the present review attempts to explore the health effects of hard water and its constituents. This Drinking Water Health Advisory contains Health Advisories as well as aesthetic properties (e.g., taste, odor, color) of manganese in drinking water. Of all the cardiovascular risk factors, magnesium now takes first place as judged by the accumulation of epidemiological, pathophysiological, clinical and experimental data, both pharmacological and therapeutic. I didn't find anything about the threshold value of magnesium in drinking water via the World Health Organization. It makes up 2.5 percent of the Earth’s crust and is commonly found in such minerals as magnesite, Age- and gender-adjusted calcium intake from drinking water was inversely associated with hypertension death risk. supported the hypothesis that extra magnesium and/or calcium in drinking-water can contribute to reduced cardiovascular disease and other health benefits in populations. Cases lived in municipalities in which 90.6% of the population was served by a waterworks. Also all the subjects used for the present study were at least 50 years old, and it is assumed that the elderly are more likely to remain in the same residence and, therefore, that most of their lifetime was spent at the address listed on the death certificate. There is also some evidence that calcium and magnesium in drinking water may help protect against gastric, colon, rectal cancer, and pancreatic cancer, and that magnesium may help protect against esophageal and ovarian cancer. This potential is calculated with 2010 global mortality figures combined with a recent quantification of water-magnesium’s inverse association with heart disease and stroke mortality. Each case and its matched control had residence and place of death in the same municipality. No municipalities were excluded because of changes in water quality (eg, the use of water softeners) during the past few decades. Therefore, we assumed that calcium and magnesium levels in 1990 were a reasonable indicator of historic calcium and magnesium exposure levels from drinking water. In the analysis, the subjects were divided into quintiles according to the levels of calcium and magnesium in their drinking water. : 16.Ma J, Folsom AR, Melnick SLet al. The control group consisted of people who died from other causes and the controls were pair matched to the cases by sex, year of birth, and year of death. Anaheim Convention Center, Send Email to The Magnesium Online Library, Pages 440 through 447 of the Report of the Safe Drinking Water Committee, The High Heart Health Value of Drinking-Water Magnesium, Head Injuries, Central Nervous System Injuries. Drinking water comes with a variety of mineral contaminants. Data on calcium and magnesium levels in drinking water throughout Taiwan have been obtained from the Taiwan Water Supply Corporation. The OR in relation to magnesium levels in drinking water are shown in Table 3. They also conduct routine water analyses to assess the suitability of water for drinking from both the sources and at various points in the distribution system. An inverse relationship between dietary magnesium and BP has also been reported.14–19. Taiwan is divided into 361 administrative districts, which will be referred to herein as municipalities. PDF: The High Heart Health Value of Drinking-Water Magnesium. Tastes great! The correlation between 1980 and 1990 hardness levels for the study areas was reasonably high (r = 0.85). The case group consisted of all eligible hypertension deaths (including deaths caused by essential hypertension (International Classification of Disease, ninth revisions [ICD-9], code 401), hypertensive heart disease (ICD-9 code 402), hypertensive renal disease (ICD-9 code 403), hypertensive heart and renal disease (ICD-9 code 404), and secondary hypertension (ICD-9 code 405)) occurring in people between 50 and 69 years of age. Spigot located at Adobe Springs, 24 hours a day, 7 days a week, at 19,000 Del Puerto Data on all deaths of Taiwan residents from 1990 through 1994 was obtained from the Bureau of Vital Statistics of the Taiwan Provincial Department of Health, which is in charge of the death registration system in Taiwan.

There is no evidence of adverse health effects specifically attributable to magnesium in drinking water. Iron and manganese are not health concerns in drinking water. Books about magnesium! : Oxford University Press is a department of the University of Oxford. effects of contaminants in drinking water. "According to the U.S. National Academy of Sciences (1977) there have been more than 50 studies, in nine countries, that have indicated an inverse relationship between water hardness and mortality from cardiovascular disease. The U.S. National Academy of Sciences has estimated that a nation-wide initiative to add calcium and magnesium to soft water might reduce the annual cardiovascular death rate by … the effects on human health of the substances or contaminants of potential health concern in drinking-water. The levels of calcium and magnesium of that municipality were used as an indicator of exposure to those substances for an individual residing in that municipality. Some of the conditions magnesium may be useful in treating or preventing are: Articles are listed under one heading only. There is unfortunately no information available on these variables for individual study subjects and they could not be adjusted for directly in the analysis. PDF. Epidemiol Rev. This is a fact sheet intended for health professionals. Synthesis and sintering of B, Sr, Mg multi-doped hydroxyapatites: Structural, mechanical and biological characterization. The results of the present study show that there is a significant protective effect of magnesium intake from drinking water on the risk of hypertension.

Instead, they both have secondary or recommended drinking water standards because they cause aesthetic problems that make the water undesirable to use in the home and a bitter metallic taste that can make the water unpleasant to drink for both humans and farm animals.Iron can also cause an orange or brown stain in sinks and in the laundry. Heart Disease. 14 pages. Chun-Yuh Yang, Hui-Fen Chiu, Calcium and magnesium in drinking water and the risk of death from hypertension, American Journal of Hypertension, Volume 12, Issue 9, September 1999, Pages 894–899, https://doi.org/10.1016/S0895-7061(99)00065-5.
