Alkaline water may provide temporary relief from acid reflux
Alkaline water has a higher pH level than regular drinking water, typically with a pH of 8 or 9, compared to the neutral pH of 7 in regular drinking water. Some advocates of alkaline water believe that it can neutralise the acid in the body, specifically the stomach acid that causes acid reflux. However, these claims are not supported by research.
A 2019 study by Hassan Tariq and his team suggested that drinking water can help clear acid from the oesophagus, providing relief from acid reflux. The higher pH of alkaline water may help neutralise stomach acid and alleviate acid reflux symptoms. André-Michael Beer and his team also found that drinking water with high levels of hydrogen carbonate content may assist in reducing the severity and frequency of acid reflux.
However, it is important to note that there is insufficient scientific evidence to support the health claims made by users and sellers of alkaline water. Many health professionals argue that more research is needed to validate these claims. Additionally, drinking excessive amounts of water can disrupt the balance of minerals in the stomach and potentially increase the likelihood of acid reflux.
While alkaline water may provide temporary relief from acid reflux, it should not be solely relied upon. It is recommended to combine it with other lifestyle changes and medication, especially for those with GERD (Gastroesophageal Reflux Disease). Consulting a healthcare professional is advisable to determine the most suitable treatment approach for acid reflux, as individual responses may vary.

There is no evidence that alkaline water can prevent cancer
Alkaline water is water that has been treated to make it less acidic and give it a higher pH level than regular drinking water. Regular drinking water has a neutral pH of 7, while alkaline water typically has a pH of 8 or 9. Proponents of alkaline water claim that it can neutralise the acid in the body and prevent cancer. However, there is no scientific evidence to support these claims.
The theory behind the idea that alkaline water can prevent cancer is that cancer cells thrive in an acidic environment, so consuming alkaline water may prevent tumours from forming. However, cancer experts say that drinking alkaline water does not impact the pH level of the blood, so it would not affect tumour growth. The human body is designed to maintain a safe, slightly alkaline level of 7.4, and it naturally balances its internal pH level. While tumour cells may produce lactic acid, it is usually not enough to alter the body's pH level.
Some studies have suggested that alkaline water might have some health benefits. For example, a 2022 study found that women who drank alkaline water were less likely to have metabolic syndrome, which includes risk factors such as high blood sugar and blood fats, elevated blood pressure, and belly fat. However, there was little difference in weight between women who drank alkaline water and those who didn't, and more research is needed to prove that alkaline water improves metabolism. Another small 2018 study found that athletes who drank alkaline water performed better during rigorous workouts.
While alkaline water is generally considered safe to drink, it is not necessary for health or cancer prevention. It may also have some negative effects, such as interfering with nutrient absorption and causing dryness or irritation if used on the skin.

Alkaline water is less acidic than regular water
Proponents of alkaline water believe that it can neutralise the acid in the body, though there is little scientific evidence to support this claim. The theory behind the alkaline diet suggests that replacing acid-forming foods with alkaline foods can improve health and prevent serious diseases like cancer. However, cancer experts refute this, stating that drinking alkaline water does not impact the pH level of the blood and, therefore, would not affect tumour growth.
Some studies have suggested potential health benefits associated with drinking alkaline water. For example, a 2018 study found that athletes who drank alkaline water performed better during rigorous workouts. Another study from the New York Medical College found that consuming pH 8.8 alkaline water alleviated acid reflux symptoms. Additionally, a 2022 study reported that postmenopausal women who drank at least one litre of alkaline water per day for two months experienced marginal reductions in blood sugar, cholesterol, and blood pressure.
Despite these findings, many health professionals maintain that there is insufficient research to support the numerous health claims made by users and sellers of alkaline water. Some doctors and researchers argue that the claims are not backed by quality research, and there are safety concerns associated with regular consumption of alkaline water. For instance, it may hinder growth, deplete minerals and vitamins from the body, and interfere with nutrient absorption.

There is little evidence that alkaline water promotes weight loss
Alkaline water is water that has been treated to have a higher pH level than regular drinking water. Regular drinking water has a neutral pH of 7, while alkaline water typically has a pH of 8 or 9. The main idea behind the alkaline diet is that consuming or avoiding certain foods can change the body's pH levels, and that these pH levels are associated with different health conditions.
One common claim about alkaline water is that it boosts metabolism and helps with weight loss. However, there is little evidence to support this assertion. In a 2022 study published in PLoS One, researchers found that women who drank alkaline water were less likely to have metabolic syndrome, which includes risk factors such as high blood sugar, blood fats, elevated blood pressure, and belly fat. However, there was little difference in weight between the women who drank alkaline water and those who did not.
While some proponents of the alkaline diet suggest that people monitor their urine pH to ensure it is alkaline, this is not an accurate indicator of overall body pH and general health. Urine pH can vary greatly, and diet does not significantly affect blood pH in healthy individuals. The body has several effective ways to regulate blood pH, and the kidneys play a crucial role in maintaining the necessary pH range for life.
Additionally, the potential benefits of alkaline water for weight loss may be outweighed by possible disadvantages. Drinking alkaline water with a pH level above 9 can lead to a bitter taste and may be dangerous for individuals who regularly take stomach acid production blockers. There are also concerns that regularly consuming alkaline water could hinder growth, deplete minerals and vitamins, and interfere with nutrient absorption.
In conclusion, while the alkaline diet may have some health benefits due to its emphasis on whole foods and reducing processed foods, there is little evidence to support the claim that alkaline water specifically promotes weight loss. More research is needed to prove any direct correlation between alkaline water consumption and metabolic changes or weight loss.

Alkaline water may be unsafe for people with kidney disease
Alkaline water is water that has a higher pH level than regular drinking water, typically with a pH of 8 or 9. It is believed by some to have unique health advantages, such as neutralizing acids that contribute to gastroesophageal reflux disease (GERD) and enhancing hydration. However, these claims are not supported by scientific research. While some studies suggest that alkaline therapies may benefit patients with kidney disease, there is no conclusive evidence to support these claims.
The kidneys are responsible for regulating the blood's pH level and maintaining the balance of vitamins, minerals, and nutrients in the body. Altering the body's pH level through a high-alkaline diet may not be suitable for all patients with kidney disease, and it is essential to consult with a medical professional before making any dietary changes.
One concern regarding alkaline water is the potential impact on kidney function. The kidneys regulate blood pH by reabsorbing water and electrolytes and removing excess hydrogen ions. Drinking alkaline water with a pH greater than 9.8 may disrupt this delicate balance and lead to health issues.
Additionally, the production methods of alkaline water have raised safety concerns. The water quality before ionization is crucial to ensuring the absence of contaminants. Some scientists recommend using reverse osmosis to purify water before increasing its pH and adding minerals.
While there are claims that alkaline water can be beneficial for kidney health, it is important to approach these assertions with caution. The current lack of conclusive scientific evidence underscores the necessity of seeking personalized medical advice before incorporating alkaline water into the diet, especially for individuals with kidney disease.
