Introduction:
The popularity of alkaline water has grown significantly in recent years, with many enthusiasts claiming that it can improve health and prevent diseases. But is there any truth to these claims? In this article, we will explore the potential benefits of alkaline water, the reasons why people consume it, and whether it is truly better than ordinary water.
What is Alkaline Water?
Alkaline water is simply water that has a pH level above 7 on the pH scale, which ranges from 0 to 14. A pH of 7 is considered neutral, while values above 7 are alkaline. Tap water typically has a pH range of 6.5 to 7.5, whereas alkaline water has a pH range of 8.0 to 10.0.
To achieve an alkaline pH, devices called water ionizers are used to increase the pH level of tap water. These devices create an ionic imbalance and increase the concentration of hydroxide ions in the water, making it more alkaline.
Why Drink Alkaline Water?
Although there is much media hype surrounding alkaline water, there is limited scientific evidence to support its benefits. However, some research suggests that alkaline water might have therapeutic benefits for individuals with gastroesophageal reflux disease (GERD).
A study found that alkaline water with a pH of 8.8 can neutralize the digestive enzyme pepsin in the stomach, reducing symptoms of acid reflux. Additionally, alkaline water may have a buffering capacity that helps reduce stomach acidity.
However, it is important to note that these benefits of alkaline water for GERD are not widely accepted by the scientific community and require further research.
The Alleged Benefits of Alkaline Water
There are numerous alleged benefits of alkaline water that lack strong scientific evidence. Some individuals claim that alkaline water can alkalize the body, slow down aging, or even cure cancer. However, there is no scientific proof to support these claims.
It is crucial to maintain a skeptical attitude towards unsubstantiated claims and consult reliable sources before believing in the benefits of alkaline water.
The Body’s Acid-Base Balance
Another common claim about alkaline water is that it helps maintain the body's acid-base balance. However, it is important to understand that our bodies have a natural ability to regulate their acid-base balance, regardless of our dietary choices.
The pH of human blood is naturally maintained within a narrow range between 7.35 and 7.45, which is slightly alkaline. This balance is critical for optimal cellular function. Drinking alkaline water will not alter the body's acid-base balance, as it is already regulated by our internal systems.
The Side Effects of Alkaline Water
Consuming moderate amounts of alkaline water (pH of 7.0 to 8.5) is considered safe and should not result in any adverse side effects. However, drinking excessive amounts of highly alkaline water (pH of 9 to 10) can cause stomach discomfort. Additionally, alkaline water may lower the pH of gastric acid, which can affect the absorption of oral medications.
It is important to note that if you are taking prescription medications, it is advisable to consult your healthcare professional before drinking alkaline water, as it may interfere with the effectiveness of certain medications.
How to Make Alkaline Water at Home
There are several methods to prepare alkaline water at home. The simplest approach is to add a pinch of baking soda to a glass of tap water. Baking soda has a pH of approximately 9, which increases the alkalinity of the water. However, excessive consumption of baking soda can have negative health effects.
Another method involves adding alkaline fruits and vegetables to tap water. For example, you can add cucumber slices to a pitcher of water and let it sit in the refrigerator for a few hours before drinking. This can give the water a slight alkalinity and a refreshing flavor.
There are also commercially available water filters and ionizing machines that produce alkaline water. However, before investing in an expensive device, it is recommended to test the pH of your tap water to determine if it is already balanced or slightly alkaline.
