The pH of the water you drink matters. Alkaline water has been compared to acidic water in clinical testing and alkaline water has been shown to have a beneficial effect on some health issues. Acidic water has been shown to have no effect on health, or in some cases it may have a negative effect on health.
Alkaline water better than acidic water for calcium nutrition
The World Health Organization recommends you get 10 – 20 % of your daily needs for essential minerals like calcium from drinking water. A study called: Alkaline mineral water lowers bone resorption even in calcium sufficiency compared the effect of alkaline water and acidic water on calcium retention in the body. Both waters had equal amounts of calcium added to them. The alkaline water was shown to reduce calcium loss, and lowered two important markers of bone loss. Acidic water was shown to have no effect on calcium loss, and did not reduce markers of bone loss.
Alkaline water better, safer, than acidic water
Minerals like calcium are 30% easier for the body to absorb from water than they are from food. If your water is alkaline, you get healthy minerals in it, if your water is acidic, you can absorb toxins like mercury from it. It’s probably OK to drink tap water because the EPA requires the pH of tap water to be at least 6.5. But beware of distilled water or water from Reverse Osmosis; both of these become acidic when exposed to air.
For healthy bones your water had better be alkaline. Drinking water is the best way to get essential minerals for good health. Research shows that you get benefits from the calcium in alkaline water – even if you get enough calcium in your diet! Acidic water has no effect on bone health. You can avoid drinking acidic water; simply avoid distilled or reverse osmosis water (or add minerals to it before drinking).
