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. 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. Health Considerations Essentiality. Mortality data differences between the municipalities in this study do not appear to result from systematic differences in recording and codification. Also, there is substantial geographic variation in hypertension mortality within the country. Tastes great! 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. Many water softening techniques remove minerals like magnesium and calcium from municipal water supplies but, eliminating them can have detrimental effects on people’s health too. The main variables responsible for the sharp difference between the age- and gender-adjusted and full multivariate model were magnesium levels in drinking water and urbanization level of residence. 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. This study used a death certificate-based case-control study and a drinking water quality ecology study to examine the relationship between hypertension mortality and calcium and magnesium exposure from drinking water in Taiwan. Data on calcium and magnesium levels in drinking water throughout Taiwan have been obtained from the Taiwan Water Supply Corporation. Under normal conditions, magnesium levels are carefully regulated, and short-term dietary deficiencies can... Absorption, Distribution and Excretion. 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. 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. Box 1417 Spigot located at Adobe Springs, 24 hours a day, 7 days a week, at 19,000 Del Puerto : 21.Rubenowitz E, Axelsson G, Rylander R: 35.Theophanides T, Angiboust JF, Polissiou M: 40.Cutler JA, Follmann D, Elliott Pet al. Magnesium intake from drinking water was significantly inversely associated with hypertension death risk in a model controlling for age and gender. Subjects who died from gastric cancer (ICD code 151) and colorectal cancer (ICD code 153) were also excluded from the control group because of previously reported negative correlation with hardness (calcium or magnesium) levels in drinking water.24–26 Control subjects were pair matched to the cases by gender, year of birth, and year of death. 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). Also fear of hypertension should not deter anyone from drinking water with low magnesium levels. The significant association between mortality from hypertension and the levels of magnesium in drinking water is supported by knowledge of the functions of magnesium. Cases had a higher rate (43.6%) of living in metropolitan municipalities than the controls (37.9%) (Table 1). 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. Interest concerning the role of calcium and magnesium in human cardiovascular disease was stimulated by ecologic studies that demonstrated an inverse association between water hardness and cardiovascular death rates.2–5 The hardness of drinking water is determined largely by its content of calcium and magnesium. 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. 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. Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply.Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be delivered to homes. Consumers can take FREE magnesium rich water at the Free 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. NSF International and the International Life Sciences Institute assembled a diverse group of nutrition, medical, epidemiological and scientific experts in Baltimore, MD on April 24-26 for an International Symposium on Health Aspects of Calcium and Magnesium in Drinking Water. 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. The increased magnesium group had a 27% to 37% lower risk of death from hypertension. Many of them cover more than one subject. 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. Hard water is water that has high mineral content (in contrast with "soft water"). : 10.Ackley S, Barrett-Connor E, Suarez L: 12.Gruchow HW, Sobocinski KA, Barboriak JJ: 15.Witteman JCM, Willett WC, Stampfer MJet al. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Use the search to find additional articles on your subject. In the multivariate model, the inverse association was somewhat stronger. Magnesium links! loading. This report examines whether calcium and magnesium in drinking water are protective against hypertension. This study was partly supported by a grant from the National Science Council, Executive Yuan, Taiwan (NSC-87-2314-B-037-074). 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. Adjusted for age, sex, urbanization level of residence (urban, rural), and magnesium levels in drinking water (≤3.8, 3.9–8.2, 8.3–11.1, 11.2–16.3, ≥16.4). This is an important finding for the Taiwan water industry and human health risk assessment. Abstract. supported the hypothesis that extra magnesium and/or calcium in drinking-water can contribute to reduced cardiovascular disease and other health benefits in populations. Ray Tackaberry, Successor Librarian The samples were then analyzed by the waterworks laboratory office using standard methods. In Taiwan, the mean daily intake of dietary calcium is 507 mg. the contribution of drinking water to calcium and magnesium intake; health significance of calcium and magnesium; role of drinking-water in relation to bone metabolism; epidemiological studies and the association of cardiovascular disease risks with water hardness and magnesium in particular; water production, technical issues and economics. 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. Magnesium in water appears as hydrated ions, which are more easily absorbed than magnesium in food.22,35 The contribution of water magnesium among persons who drink water with high magnesium levels could thus be crucial in the prevention of magnesium deficiency. Licensed by the California Department of Health A control group was formed using all other deaths, excluding those deaths that were associated with cardiovascular diseases. Data collected included the mean levels of calcium and magnesium for the year 1990. 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. 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. 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. There are products designed to “fortify” such deionized or distilled water with magnesium … A water filtration system can help remove unwanted iron from your water supply and easily remove metallic tastes and odors. 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. 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. 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. (Dr. Rowe has linked the cardiovascular complications of space flight with magnesium deficits). Four finished water samples, one for each season, were collected from each waterworks. Furthermore, Taiwan is a small island with a convenient communication network, and the accessibility of medical service facilities is comparable among study municipalities. A recently proposed hypothesis suggests that an impairment of the cell membrane sodium transport system is responsible for the increased total peripheral resistance found in essential hypertension.36 Magnesium is an enzyme (Na/K-ATPase) activator and regulates cellular energy metabolism, vascular tone, and cell membrane ion transport. Is the RDA for Magnesium Too Low? 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. Hypertension is one of the most important risk factors for cardiovascular and cerebrovascular diseases, especially stroke. Iron is an essential element in human nutrition, and the health effects of iron in drinking water may include warding off fatigue and anemia. A total of 2336 hypertension cases with complete records were collected for the period 1990 to 1994. The OR in relation to magnesium levels in drinking water are shown in Table 3. Iron oxides or iron carbonates can give a reddish brown colouration to hard water deposits . Sources of Hardness Minerals in Drinking Water; Water is a good solvent and picks up impurities easily. Also, magnesium competes with calcium for absorption. 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. These can include calcium, magnesium, manganese, and so on. Cases lived in municipalities in which 90.6% of the population was served by a waterworks. We believe that this ameliorates the migration problem. The urbanization level of each municipality was based on the urban–rural classification scheme of Tzeng and Wu.43. 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. Some of the conditions magnesium may be useful in treating or preventing are: Articles are listed under one heading only. Odds ratios (OR) and 95% confidence intervals (CI) for hypertension death by calcium levels in drinking water, 1990–1994. : 16.Ma J, Folsom AR, Melnick SLet al. The completeness and accuracy of a death registration system should be evaluated before any conclusion based on the mortality analysis is made. Several studies have reported that calcium and magnesium in drinking water have a dose-dependent protective effect when it comes to cardiovascular disease. 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. 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. Magnesium Fights Depression. As was described earlier, hardness is partially caused by magnesium. 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. How Many Lives Did Adobe Springs Save in 2015. They are the units that will be subjected to statistical analysis. provides information on the health and organoleptic (color, taste, odor, etc.) Odds ratio adjusted for age (50–59, 60–69 years) and sex (male, female). Books about magnesium! An inverse relationship between dietary magnesium and BP has also been reported.14–19. 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. Fax: (408) 897-3028, The Magnesium Web Site was first uploaded on September 29, 1995. 200,000,000 died from wars. Guidelines for magnesium content in drinking water are unlikely, because negative human and animal health effects are not expected. To go directly to a specific category, click on an item in the list below. 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. Thus, the present review attempts to explore the health effects of hard water and its constituents. Iron and manganese are not health concerns in drinking water. I didn't find anything about the threshold value of magnesium in drinking water via the World Health Organization. Transglutaminase 2 as a novel target in chronic kidney disease - Methods, mechanisms and pharmacological inhibition. Such a geographic distribution may suggest an environmental risk factor. Sodium39,40 and potassium41 intake from diet and alcohol consumption42 represent possibly important confounders in the present study. CONTACT: Ray Tackaberry, Successor Librarian, at (408) 897-3023 or email to ray@mgwater.com. Manganese often results in a dense black stain or solid. Among the 322 municipalities, 70 were excluded as they were supplied by more than one waterworks and the exact population served by each waterworks could not be determined. per liter. Calcium and Magnesium in Drinking-water: Public health significance. Consensus of the meeting: Nutrient minerals in drinking-water and the potential health consequences of consumption of demineralized and remineralized and altered mineral content drinking-water. In addition, the acidity of the water influences the reabsorption of calcium and magnesium in the renal tubule. DONATIONS/BEQUESTS TO SUPPORT THIS LIBRARY AND FURTHER MAGNESIUM RESEARCH WILL BE GRATEFULLY ACCEPTED. Large amounts of iron in drinking water can give it an unpleasant metallic taste. : 8.Stitt FW, Crawford M, Clayton DGet al. From the 1996 FDA Science Forum. Location: Central California, at 19,000 Del Puerto Canyon Road, Such a geographic distribution may suggest an environmental risk factor. ( Dr. Harold D. Foster , " Groundwater and Human Health," Groundwater Resources of British Columbia, Ministry of Environment, Lands, and Parks and Environment Canada, pp 6.1-6.3 (reprint), 1994. 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. Calcium also showed benefits, but the evidence wasn’t as clear-cut as it was for magnesium. Pages 440 through 447 of the Report of the Safe Drinking Water Committee of the National Academy of Sciences, 1977. Age- and gender-adjusted calcium intake from drinking water was inversely associated with hypertension death risk. Patterson, CA 95363. Our recent study found that there is a significant protective effect of magnesium but not calcium intake from drinking water against cerebrovascular disease.23 The objective of this study was to study the relationship between the levels of calcium and magnesium in drinking water and risk of death from hypertension in Taiwan. 1997;19(2):258-72. Information on magnesium! You may be thinking, aren’t these all minerals that are good for our health? In addition, iron and manganese bacteria are not known to present a health risk. 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. 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. A guideline for magnesium has therefore not been specified. This is a fact sheet intended for health professionals. It is expressed as the equivalent amount of calcium carbonate that could be formed from the calcium and magnesium in solution. In more severe cases, older pipes may need to be replaced, or your system may need to be flushed. Hard water is not a health risk, but a nuisance because of mineral buildup on fixtures and poor soap and/or detergent performance. Adverse Effects. There is no evidence of adverse health effects specifically attributable to magnesium in drinking water. For a reader-friendly overview of Magnesium, see our consumer fact sheet on Magnesium.. Introduction. 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. Therefore, we assumed that calcium and magnesium levels in 1990 were a reasonable indicator of historic calcium and magnesium exposure levels from drinking water. Odds ratios (OR) and 95% confidence intervals (CI) for hypertension death by magnesium levels in drinking water, 1990–1994. 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. The number of visitors to this page beginning September 29, 1995 is: Call for papers--previously published or original, Program Announcement, April 24, 2010, Ray Tackaberry, Successor Librarian. This figure would contribute, on average, 13.7% to an individual's total dietary calcium intake, given a daily consumption of 2 L of water. PDF: The High Heart Health Value of Drinking-Water Magnesium. Because the laboratory office examines calcium and magnesium levels on a routine basis using standard methods, it was thought that the problem of analytical variability was minimal. The adjusted odds ratios (95% confidence interval) for the highest versus lowest quintiles of exposure was 0.63 (0.47 to 0.84). Interest concerning the role of calcium and magnesium in human cardiovascular disease was stimulated by ecologic studies that demonstrate… Heart Attack, Atherosclerosis, Cardiovascular Disease, etc. Canyon Road, Patterson, CA 95363. 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 150,000 in the United States." By comparison, in the previous century only about The association was even positively, although not significantly, associated with the risk of hypertension in the fully adjusted model. Not only, calcium and magnesium, but other constituents also affect different health aspects. Many studies have demonstrated a negative association between blood pressure and calcium and magnesium levels. However, there is no reason to believe that there would be any correlation between these confounders and the levels of magnesium in the 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. How to Treat Magnesium and Iron in Drinking Water. School of Public Health, Kaohsiung Medical College. Water described as "hard" is high in dissolved minerals, specifically calcium and magnesium. Each matched control was selected randomly from the set of possible controls for each case. Excluded from the analysis were 30 aboriginal townships and 9 islets that had different lifestyles and living environments. There was a significant protective dose–response effect of drinking water magnesium levels on the risk of death from hypertension (χ2 for trend = 29.05, P < .001). We need to better understand the interrelation of various water and food constituents, as well as individual risk factors, in the pathogenesis of IHD. Taiwan is divided into 361 administrative districts, which will be referred to herein as municipalities. may not be sold. Synthesis and sintering of B, Sr, Mg multi-doped hydroxyapatites: Structural, mechanical and biological characterization. Address correspondence and reprint requests to Dr. Chun-Yuh Yang, 100 Shih-Chuan 1st RD, Kaohsiung 80708, Taiwan. 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. 2 pages. One-half cup, or 4 ounces, of Magnesium Water yields 90 mg of magnesium; one-cup, 8 ounces, yields 180 mg magnesium. 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. They are the units that will be subjected to statistical analysis.

For controls this number was 89.8%. Magnesium plays a critical role in brain function and mood, and low … 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. 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.
