What Is Alkaline Water?
Answer :
Water is important to every cell, tissue, and organ in your body. The best way to stay hydrated: glug-glug-glug glasses of water throughout the day. But which kind of water? Some people claim that alkaline water is better than anything you could get from the tap. But the science isn't there to back it up.
What Makes Alkaline Water Different?
Answer :
Water is a combination of hydrogen and oxygen. That's why you call it H2O. The amount of hydrogen in water is measured as pH levels. Alkaline water has more hydrogen or a higher pH than regular water. The lower the hydrogen level, the higher the acid levels. Water’s pH level ranges on a scale from 0 to 14. Seven is considered neutral or balanced between acidic and alkaline. If water is below 7 on the pH scale, it's "acidic." If it's higher than 7, it's "alkaline." Bottled alkaline water has a pH level above 7. In some cases, manufacturers use a special device to change the chemical makeup of the water. Other times, they add nutrients to the water to change its pH. For comparison, orange juice has a pH of 3.3 and black coffee is about a 5. Pure water has a neutral pH of 7. But tap water in the U.S. tends to fall below that in the 4.3 to 5.3 range depending on where you live.
Checking the Health Claims:
Answer :
Alkaline water enthusiasts claim that its increased hydrogen provides greater hydration than regular water, especially after a hard workout. Fans of the stuff also say that regular drinking water with a pH below 7 creates too much acid in your blood and cells. They blame plain water's low pH for all sorts of health problems, from osteoporosis to cancer.
Water that is more alkaline supposedly reduces acid in the bloodstream and:
  • Improves metabolism
  • Increases energy
  • Slows aging
  • Improves digestion
  • Reduces bone loss
Can Alkaline Water Do All This?
Answer :
The health claims about alkaline water are more about sales than science. There isn't much research to support them. Also, your body, on its own, can keep your pH levels at an even keel. Your kidneys are your built-in filtration system. It's their job to balance the acid levels in your body. If your blood gets too acidic, your body brings it down by breathing out more carbon dioxide. Your stomach is the great equalizer. Your gastric juices -- a combination of digestive enzymes and hydrochloric acid -- neutralize everything you eat and drink. Basically, your stomach will re-acidify alkaline water before it can do anything the health claims promise.
