Understanding the Science Behind Alkaline Water

The pH Scale and Water

The pH scale is a measure of how acidic or alkaline a substance is, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral. When it comes to water, the pH can vary significantly depending on its source and treatment. In Australia, the normal pH range for drinking water is between 6.5 and 8.5, as specified by the Australian Drinking Water Guidelines (National Health and Medical Research Council, 2011).

Alkaline water machines aim to increase the pH of water, typically to a range of 8.0 to 9.5. This is achieved through a process called electrolysis, which separates water molecules into acidic and alkaline components. The alkaline portion is then used for consumption, while the acidic water is typically discarded or used for other purposes such as cleaning.

It's important to note that while alkaline water has a higher pH than regular tap water, the human body has sophisticated mechanisms to maintain its internal pH balance. The stomach, for instance, produces hydrochloric acid to maintain an acidic environment necessary for digestion, regardless of the pH of consumed water (Koufman & Johnston, 2012).

Electrolysis and Ionization Process

Alkaline water machines use electrolysis to produce alkaline water. This process involves passing water over electrically charged plates, typically made of platinum-coated titanium. As water flows over these plates, it is separated into two streams:

1. Alkaline water (higher pH): Contains negatively charged hydroxyl ions (OH-)
2. Acidic water (lower pH): Contains positively charged hydrogen ions (H+)

The alkaline water, which is rich in hydroxyl ions, is collected for drinking, while the acidic water is typically discarded or used for other purposes like cleaning or watering plants.

During this process, the machine also produces molecular hydrogen (H2), which some researchers believe may have antioxidant properties (Ohta, 2011). However, it's important to note that the concentration of molecular hydrogen in alkaline water can vary greatly depending on the specific machine and process used.

Potential Health Effects of Alkaline Water

While proponents of alkaline water claim numerous health benefits, it's crucial to approach these claims with caution, as scientific evidence is still limited and often inconclusive. Some potential effects that have been studied include:

1. Acid reflux: A study by Koufman and Johnston (2012) suggested that alkaline water with a pH of 8.8 might help deactivate pepsin, an enzyme involved in acid reflux. However, more research is needed to confirm these effects.

2. Hydration and exercise recovery: Some studies have suggested that alkaline water might enhance hydration status and improve exercise-induced metabolic acidosis. For instance, a study by Weidman et al. (2016) found that consumption of alkaline water was associated with improved hydration status after exercise-induced dehydration. However, these findings are not universally accepted and require further investigation.

3. Bone health: There's some speculation that alkaline water might help prevent bone loss, but evidence is limited. A study by Wynn et al. (2009) found no significant difference in bone resorption markers between subjects consuming alkaline water versus regular water.

4. Blood pressure: Limited research has suggested a potential link between alkaline water consumption and reduced blood pressure, but these findings are preliminary and require further validation (Tanaka et al., 2012).

Limitations of Current Research

It's crucial to interpret the potential health effects of alkaline water with caution. Many studies in this field have limitations, including small sample sizes, short durations, and potential conflicts of interest. The Australian Government's Therapeutic Goods Administration (TGA) has not approved any specific health claims for alkaline water.

Moreover, the long-term effects of consuming alkaline water are not well understood. Some researchers have raised concerns about potential negative effects, such as reducing stomach acidity, which could interfere with digestion and increase susceptibility to certain infections (Fenton & Huang, 2016).

Given these limitations, consumers should approach alkaline water as a personal choice rather than a proven health intervention. It's always advisable to consult with healthcare professionals before making significant changes to one's diet or water consumption habits.
