Understanding Alkaline Water Ionizers: Kangen Water vs. Naturopress

What Are Alkaline Water Ionizers?

Alkaline water ionizers are devices that use electrolysis to separate water into alkaline and acidic components. This process allows users to adjust the pH level of their drinking water, typically making it more alkaline. The basic principle behind these machines involves passing water over electrically charged plates, which causes the water molecules to split into positively charged hydrogen ions and negatively charged hydroxide ions (Huang et al., 2018).

Most alkaline water ionizers, including both Kangen and Naturopress models, incorporate built-in filtration systems to remove impurities from the water before the ionization process. These systems typically use activated carbon filters and other media to reduce contaminants like chlorine, sediment, and some heavy metals.

The key features of alkaline water ionizers include:

• Adjustable pH levels, usually ranging from slightly acidic (around pH 6) to highly alkaline (up to pH 11 or higher)
• Production of water with negative oxidation-reduction potential (ORP), which is claimed to have antioxidant properties
• Multiple water types for different uses (e.g. drinking, cooking, cleaning)
• Self-cleaning functions to prevent scale buildup on the electrodes

Proponents of alkaline water claim various health benefits, including improved hydration, acid reflux relief, and enhanced antioxidant intake. However, it's crucial to note that many of these claims lack robust scientific evidence, and more research is needed to conclusively prove the purported health benefits of alkaline water (Fenton & Huang, 2016).

The Science Behind Alkaline Water

The current scientific understanding of alkaline water effects is limited, with mixed results from existing studies. While some research suggests potential benefits, the overall evidence is not strong enough to make definitive health claims.

A systematic review by Fenton et al. (2016) examined the available evidence on alkaline water consumption and concluded that there was a lack of high-quality studies to support many of the claimed benefits. The review found some limited evidence for potential effects on acid-base balance and hydration status, but noted that more rigorous research is needed.

Some proposed mechanisms of action for alkaline water include:

1. Improved hydration: Some studies suggest that the smaller water cluster size in ionized water may enhance cellular hydration (Weidman et al., 2016).

2. Antioxidant effects: The negative ORP of alkaline water is thought to potentially neutralize free radicals, though this effect may be limited when consumed orally due to stomach acid (Shirahata et al., 2012).

3. Acid-base balance: Alkaline water consumption may have a mild alkalizing effect on the body, potentially helping to buffer acid load from diet and metabolism (Koufman & Johnston, 2012).

However, it's important to approach these potential mechanisms with caution, as the human body has robust systems in place to maintain pH balance, and the effects of alkaline water consumption may be minimal in healthy individuals.

Given the current state of evidence, health authorities and researchers generally advise against making strong health claims about alkaline water. The Australian Therapeutic Goods Administration (TGA) has strict guidelines on advertising health products and warns against making unsubstantiated health claims (TGA, 2020).

How do water ionisers affect the mineral content of water, and is this beneficial or detrimental?

Water ionisers can affect the mineral content of water in several ways:

• Concentration of minerals: The ionisation process tends to concentrate certain minerals in the alkaline fraction of the water, potentially increasing mineral content.
• Bioavailability: Some proponents claim that the ionisation process makes minerals more bioavailable, though scientific evidence for this is limited.
• Mineral types: Ionisers may affect different minerals to varying degrees. Calcium and magnesium, for example, are often concentrated in the alkaline water.
• Potential loss of trace minerals: Some trace minerals might be lost or reduced during the ionisation process.

The impact of these changes can be both potentially beneficial and detrimental:

Benefits: - Increased mineral intake: For those with low mineral intake, ionised water could provide additional minerals. - Potential improved absorption: If the claim of increased bioavailability is true, it could enhance mineral absorption.

Potential drawbacks: - Mineral imbalances: Excessive consumption of certain minerals could lead to imbalances in some individuals. - Loss of beneficial trace minerals: The potential loss of some trace minerals could be a drawback, especially if these are not obtained from other dietary sources.

It's important to note that the mineral content of ionised water can vary based on the source water and the specific ioniser used. Additionally, for most healthy individuals with a balanced diet, the mineral content of water (ionised or not) is not a significant factor in overall mineral intake. As always, it's advisable to consult with a healthcare professional for personalised advice.

How do water ionisers perform in areas with hard water, and what additional maintenance might be required?

Water ionisers can function in areas with hard water, but they may require additional care and maintenance:
