According to the data of the Centers for Disease Control and Prevention (CDC), about 75 million adults in the United States suffer from hypertension, which caused or caused more than 465,438+00,000 deaths in 2065,438+04. Excessive blood pressure will increase the force of circulating blood on the arterial wall. If this situation continues, it may damage the heart and increase the risk of stroke and other health problems. A recent study linked drinking water with high salinity to lowering blood pressure. The researchers explained the study in a journal paper of the American Heart Association. Although water with higher salinity contains more sodium, which can raise blood pressure, it also contains more calcium and magnesium. Lead researcher Abu Mohammad Nasser said: "Calcium and magnesium have protective effects; They can lower blood pressure, "he and his collaborators attributed this discovery to the fact that the benefits of magnesium and calcium outweigh the harm of sodium. Studying people living in coastal areas provides a useful method to compare the health effects of different salinities. Nasser and his colleagues pointed out that groundwater is the main source of drinking water for more than 654.38 billion people living in coastal areas. About one-fifth of this population lives in areas where seawater flows into groundwater, resulting in different degrees of mineralization. However, they pointed out that data on "drinking water salinity, mineral intake and cardiovascular health of the population" are limited. Calcium and magnesium cancel out sodium. Their analysis collected data from two studies that recorded the coastal population of Bangladesh. The measurement covers the period when the salinity of drinking water changes due to monsoon and dry weather. The research team found that people who drink low-salinity or medium-salinity water have higher sodium content in urine than those who drink low-salinity fresh water. In addition, people with higher urinary sodium levels also have higher systolic blood pressure. In addition, the analysis shows that people who drink moderate and moderate salinity water have higher calcium and magnesium contents in their urine. The higher content of these minerals is related to the lower systolic and diastolic blood pressure. For example, the average systolic blood pressure of people who drink "lightly salinized" water is lower than 1.55 Hg, and the average diastolic blood pressure is lower than that of people who drink fresh water 1.26 mm Hg. They cited studies that found similar effects in other parts of the world. Some of these studies have linked drinking water rich in calcium and magnesium with reducing cardiovascular death. Dr. Robert M. Carey pointed out that although the drop in blood pressure was not large, it was large enough to have an impact, so these results deserve further study. He continued, "I think many different studies show that a small drop in blood pressure has a significant impact on reducing cardiovascular disease and stroke." "If further research does prove that calcium and magnesium fortified drinking water can lower blood pressure, it may be a brand-new way to solve the public health problem of hypertension. However, researchers point out that most people in the United States do not meet the recommended daily intake of minerals: they do not eat enough foods rich in these foods. Nasser pointed out that the consumption of mineral levels in soil caused by rainfall changes caused by climate change may also be a factor. He suggested that strengthening drinking water with beneficial minerals can make up for the shortage. He also pointed out that minerals absorbed by human body from drinking water are better than minerals absorbed from food, because their bioavailability may be lower. Ensuring the optimal concentrations of [calcium] and [magnesium] in drinking water may be an important public health and nutrition intervention to ensure that the daily needs of these basic macro minerals are met, because there is evidence that the concentrations of these minerals are decreasing all over the world.
