Use the search to find additional articles on your subject. Also, there is substantial geographic variation in hypertension mortality within the country. Iron oxides or iron carbonates can give a reddish brown colouration to hard water deposits . One-half cup, or 4 ounces, of Magnesium Water yields 90 mg of magnesium; one-cup, 8 ounces, yields 180 mg magnesium. 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).

Box 1417 They are the units that will be subjected to statistical analysis. 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. 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). It is expressed as the equivalent amount of calcium carbonate that could be formed from the calcium and magnesium in solution. The ORs for the highest versus the lowest quintile of magnesium intake from drinking water was 0.80 (95% CI 0.67 to 0.95). There is no evidence of adverse health effects specifically attributable to magnesium in drinking water. Excluded from the analysis were 30 aboriginal townships and 9 islets that had different lifestyles and living environments. Data on calcium and magnesium levels in drinking water throughout Taiwan have been obtained from the Taiwan Water Supply Corporation. 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 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. Many studies have demonstrated a negative association between blood pressure and calcium and magnesium levels. Excluded from the analysis were 30 aboriginal townships and 9 islets that had different lifestyles and living environments. 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). Magnesium intake from drinking water was significantly inversely associated with hypertension death risk in a model controlling for age and gender. Patterson, CA 95363. Low mineral intake is associated with high systolic blood pressure in the Third and Fourth National Health and Nutrition Examination Surveys: Could we all be right? 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. Tel: (408) 897-3023 This is an important finding for the Taiwan water industry and human health risk assessment. View More Articles Provided by Andrea Rosanoff here. Consumers can take FREE magnesium rich water at the Free Also fear of hypertension should not deter anyone from drinking water with low magnesium levels. Cases lived in municipalities in which 90.6% of the population was served by a waterworks. Several studies have reported that calcium and magnesium in drinking water have a dose-dependent protective effect when it comes to cardiovascular disease. For a reader-friendly overview of Magnesium, see our consumer fact sheet on Magnesium.. Introduction. Susceptible individuals who are at higher risk of being depleted of magnesium need to be identified, and potential untoward effects of magnesium … 1997;19(2):258-72. Since publication of the third edition, they comprise a series of free-standing monographs, including this one. : 21.Rubenowitz E, Axelsson G, Rylander R: 35.Theophanides T, Angiboust JF, Polissiou M: 40.Cutler JA, Follmann D, Elliott Pet al. 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. How Many Lives Did Adobe Springs Save in 2015. 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. This is a fact sheet intended for health professionals. Common symptoms include diarrhea and an upset stomach. Drinking water comes with a variety of mineral contaminants. This is an important finding for the Taiwan water industry and human health. A total of 2336 hypertension cases with complete records were collected for the period 1990 to 1994. 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. Heart Disease. No municipalities were excluded because of changes in water quality (eg, the use of water softeners) during the past few decades. The number of visitors to this page beginning September 29, 1995 is: Call for papers--previously published or original, Program Announcement, April 24, 2010, The correlation between 1980 and 1990 hardness levels for the study areas was reasonably high (r = 0.85). There are products designed to “fortify” such deionized or distilled water with magnesium … Licensed by the California Department of Health Magnesium plays a critical role in brain function and mood, and low … Magnesium levels in drinking water were inversely related to the risk of death from hypertension. School of Public Health, Kaohsiung Medical College. Hypertension is one of the most important risk factors for cardiovascular and cerebrovascular diseases, especially stroke. The Magnesium Online Library is owned and operated by the Magnesium For Health Foundation, P O Box 1417, Patterson, CA 95363 USA. An inverse relationship between dietary magnesium and BP has also been reported.14–19. 14 pages. Both cases and controls had a mean age of 62.9 years. HTML, Full text: Rolling Revision of the WHO guidelines for Drinking-Water Quality. Abstract. A systematic comparison of commercially produced struvite: Quantities, qualities and soil-maize phosphorus availability. 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.) Sources of Hardness Minerals in Drinking Water; Water is a good solvent and picks up impurities easily. Dr. Burton M. Altura and Dr. Bella T. Altura, Nutrient minerals in drinking-water and the potential health consequences of consumption of demineralized and remineralized and altered mineral content drinking-water: Consensus of the meeting. 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. However, there is no reason to believe that there would be any correlation between these confounders and the levels of magnesium in the water. 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. Canyon Road, Patterson, CA 95363. An overdose of magnesium through dietary sources is unlikely because the body will eliminate any excess magnesium from food through urine. 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. Under normal conditions, magnesium levels are carefully regulated, and short-term dietary deficiencies can... Absorption, Distribution and Excretion. After adjustment for magnesium levels in drinking water, there was no difference between the groups with different levels of calcium. As was described earlier, hardness is partially caused by magnesium. 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. Data collected included the mean levels of calcium and magnesium for the year 1990. A guideline for magnesium has therefore not been specified. Tastes great! Water with a high mineral content, or "hard" water, is also a source of magnesium. 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. Thus, the present review attempts to explore the health effects of hard water and its constituents. Despite their inherent limitations31 studies on the ecologic correlation between mortality and environmental exposures have been used widely to generate or discredit epidemiologic hypotheses. Not only, calcium and magnesium, but other constituents also affect different health aspects. Ray Tackaberry, Successor Librarian. In Taiwan, the mean daily intake of dietary calcium is 507 mg. Is the RDA for Magnesium Too Low? Copyright © 2021 American Journal of Hypertension, Ltd. Hard water is water that has high mineral content (in contrast with "soft water"). The increased magnesium group had a 27% to 37% lower risk of death from hypertension. Marx A(1), Neutra RR. 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. Most minerals from groundwater, including iron, will be absorbed by water. Taiwan is divided into 361 administrative districts, which will be referred to in this report as municipalities. ( 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. 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. Table 2 shows the numbers of cases and controls and ORs in relation to calcium levels in their drinking water. This may create collinearity in the regression model making it difficult to detect the effect of calcium. 200,000,000 died from wars. Note from Paul the Mg Librarian: 4.5 million deaths per annum from Mg-deficient drinking water would be 450,000,000 deaths over the next 100 years. 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. 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. 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. Each case and its matched control had residence and place of death in the same municipality. (Dr. Rowe has linked the cardiovascular complications of space flight with magnesium deficits). Epidemiol Rev. P.O. 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. This elimination of unsuitable municipalities left 322 municipalities for the analysis.
