Drinking more water is good for your health and can help you stay hydrated, according to scientists.
The new research suggests that drinking water that is alkaline, with less hydrogen atoms than the standard water, may help prevent certain types of cancer and other health problems.
“What we have found is that drinking alkaline water may help reduce the risk of certain cancers,” said David M. Johnson, a researcher at the University of Iowa.
“It might even prevent some of the side effects associated with drinking more hydrogen, such as high blood pressure and cardiovascular disease.”
Researchers tested the effects of a new drinking water formulation on six types of human cells, including the pancreas, colon, breast, kidney, prostate and thyroid.
The findings, published online Wednesday in the journal Nature Communications, are the latest evidence that drinking a high-quality water with less than 1,000 parts per million (ppm) of hydrogen is safe.
The study is a collaboration between researchers at the U.S. Centers for Disease Control and Prevention (CDC), the University in Illinois at Urbana-Champaign and the University at Buffalo.
The researchers first tested a formulation of water made from a blend of two types of plants: water from an algae-derived water source and water from a conventional tap.
They then tested the water with a combination of the alkaline and the standard, or distilled water, for a total of eight compounds, including hydrogen sulfide (H2SO4), which causes hydrogen to form in the water, as well as the oxygen isotope, carbon monoxide (CO).
In each case, the water was filtered, which removes the carbon dioxide.
The results were surprising, Johnson said.
The water had no noticeable effect on the immune system, but it did not significantly reduce cancer risk.
The alkaline solution was not a significant risk factor for human cells.
For example, there were no differences in the levels of nitrates in the drinking water samples between the two groups, but there was a slight decrease in the amounts of nitrate in the alkali solution compared to the distilled water.
“These results suggest that the alkalinity of drinking water may have no effect on tumor cell growth,” Johnson said in a statement.
He added that it could be important for people to use less of the standard drinking water because of health concerns.
Johnson is not the first to find that drinking more water can help protect against cancer.
A 2015 study found that drinking tap water could protect against certain types to lung cancer.
“This study shows that drinking distilled water with the highest levels of hydrogen sulfides may reduce the development of lung cancer, and there is increasing evidence that the presence of hydrogen in the blood stream is linked to a reduced risk of cancer,” Dr. Stephen G. Kull, a professor of epidemiology at the New York University School of Medicine, said in the same statement.
