Drinking Water

Are you having high blood pressure, there you’ve told to cut back on salt. You might even be taking medication. These are good strategies, as nearly half of all adults in the United States work to keep hypertension at bay. What if there were an easier way to make sure nearly everyone took at least one small step toward reducing their blood pressure every time they drank a glass of water.

Lower blood pressure levels

A new study, publish Tuesday in the Journal of the American Heart Association, suggests adding calcium and magnesium to drinking water potentially could help lower blood pressure levels across the population. The strategy stems from research that look at the impact of drinking water sources on the health of people in an area of coastal Bangladesh affect by seawater intrusion. The residents relied upon pond water or groundwater as their main water source.
The study compare blood pressure levels among people who drank salinated water with those who drank freshwater. Even though sodium is known to increase blood pressure levels, study participants who drank the salinated water had lower blood pressure. That wasn’t because of the sodium, the researchers believe, but rather because of two other minerals in the water calcium and magnesium.

Calcium and magnesium are protective; they decrease blood pressure, said Abu Mohammed Naser, a postdoctoral fellow at Emory University’s Rollins School of Public Health in Atlanta and lead author of the study. “What they suspect is happening is that they outweigh the harmful effects of sodium on blood pressure.

That’s good news for people in Bangladesh, who lack alternative sources of drinking water; so unlike people in more develop countries, where treatment plants desalinate contaminate groundwater. But the findings also could have implications for any population struggling to reduce hypertension; which is the leading preventable cause of premature death worldwide; so affecting more than 1.3 billion people globally and 116.4 million Americans.

Salinity in the water fluctuate

The analysis pooled data from two studies following participants in several communities in coastal Bangladesh; so during both dry and monsoon seasons when the amount of salinity in the water fluctuate. It find those who drank mildly salinated water; which had average systolic blood pressure levels 1.55 mmHg lower than those who drank freshwater. Their average diastolic blood pressure levels were 1.26 mmHg lower.

By testing urine samples, researchers determine those with lower blood pressure also had higher levels of calcium and magnesium in their system, which they attribute to drinking the salinated water. The reduction in blood pressure was small but significant, and worthy of further exploration, said Dr. Robert M. Carey, a professor of medicine at the University of Virginia who wasn’t involve in the new study.

Numerous studies have show both calcium and magnesium are important for maintaining good blood pressure. The use of vitamin and mineral supplements to prevent chronic diseases is not recommend, according to the Academy of Nutrition and Dietetics. In fact, the AHA recommends people get their vitamins and minerals directly from a nutrition pack diet. But most Americans fail to get the recommend daily allowance through the foods they eat.
Adding these minerals to drinking water be an effective way of counteracting some of that, Naser said. And water also make a better delivery system; hence for some minerals than food because chemicals in the food can interfere with absorption. Bioavailability is low. If you can supplement or add calcium and magnesium to water; so there is a high chance that they will be absorbed better.
