Sparkling water is also known as Carbonated water . This is prepared by mixing CO2 with water on high pressure. Carbonated water is a refreshing beverage and good alternative to sugary soft drinks.
However , some people thinks that it is not good for health.
This article covers the effects of sparkling water on health
What is Carbonated water ?
Carbonated water is a type of water in which CO2 ( Carbon Dioxide ) is mixed with high pressure.
This process creates small bubbles in the water & make it bubbly . This water is also known as sparkling water , soda , lime water , Seltzer water & fizzy water.
Carbonated water has some amounts of salts added into it to improve the taste .
Natural sparkling mineral waters, such as Perrier and San Pellegrino, are different.
These waters are captured from a mineral spring and tend to contain minerals and sulfur compounds. They are often carbonated as well.
Tonic water is a form of carbonated water that contains a bitter compound called quinine, along with sugar or high-fructose corn syrup.
Carbonated water is infused with CO2 Gas under high pressure . Sodium and other minerals are often added for taste enhancement.
Carbonated water is slightly acidic
Carbon dioxide and water infused chemically to produce carbonic acid, a weak acid that’s been shown to stimulate the same nerve receptors in your mouth as mustard.
The pH of carbonated water is between 3–4, which means it’s slightly acidic.
However, drinking an acidic beverage like carbonated water does not make your body more acidic.
Your kidneys and lungs remove excess carbon dioxide. This keeps your blood at a slightly alkaline pH of 7.35–7.45 regardless of what you eat or drink.
Carbonated water is Slightly acidic, but your body is able to maintain stable alkaline PH , no matter what you eat or drinks.
Does it affect our teethes ?
One of the biggest problems of sparkling water , that it directly effects our teethes & expose our enamel to acidic environment.
There is no clear research , but one study found that sparkling mineral water damaged enamel only slightly more than still water. Furthermore, mineral water was 100 times less damaging than a soda drink (3).
In one study, carbonated beverages showed strong effect to destroy enamel — but only if they contains sugar.
In fact, a non-carbonated sweet beverage (Gatorade) was more harmful than a carbonated sugar-free drink (Diet Coke) (4).
Another study placed samples of tooth enamel in various beverages for up to 24 hours. The sugar-sweetened carbonated and non-carbonated beverages resulted in significantly greater enamel loss than their diet counterparts (5).
A review of several studies found that the combination of sugar and carbonation may lead to severe dental decay (6).
However, plain sparkling water appears to pose little risk to dental health. Only the sugary types are harmful (7).
If you’re concerned about dental health, try drinking sparkling water with a meal or rinsing your mouth with plain water after drinking it.
Sugar-sweetened carbonated beverages erodes tooth enamel, but plain carbonated water has no effect on enamel.
Effect on Digestion ?
Carbonated water improves our digestive system in may ways :
Can improve swallowing ability
In one study, 16 healthy people were asked to repeatedly swallow different liquids. Carbonated water showed the strongest ability to stimulate the nerves responsible for swallowing (9).
Another study showed that the combination of cold temperature and carbonation strengthened these beneficial effects (10).
In a study in 72 people who felt a persistent need to clear their throats, drinking ice-cold carbonated water led to improvements in 63% of participants. Those with the most frequent, severe symptoms experienced the greatest relief (11).
May increase feelings of fullness
Carbonated water may also extend feelings of fullness after meals to a greater extent than plain water.
Sparkling water may help food remain in your stomach longer, which can trigger a greater sensation of fullness (12).
May help relieve constipation
Sparkling water is very much helpful in relieving stress from constipation.
In a 2-week research in 40 older individuals who had experienced a stroke, average bowel movement frequency nearly doubled in the group that drank carbonated water, compared with the group that drank tap water.
What’s more, participants reported a 58% decrease in constipation symptoms (14).
There’s also evidence that sparkling water may improve other symptoms of indigestion, including stomach pain.
Carbonated water has benefits for digestion. It may improve swallowing, increase feelings of fullness, and reduce constipation.
Does It Affect Bone Health
Many people believe that carbonated beverages are bad for bones because of their high acid content. However, research suggests the carbonation has no effects on the same.
A large observational study in over 2,500 people found that cola was the only beverage associated with significantly lower bone mineral density. Carbonated water appeared to have no effect on bone health (16).
Unlike carbonated water and clear soda, cola drinks contain a lot of phosphorus which effects bone density.
The researchers proposed that the cola drinkers may have been consuming too much phosphorus and insufficient calcium, providing a potential risk factor for bone loss.
In another study, teen girls who consumed carbonated drinks were found to have lower bone mineral density. This was attributed to beverages that replaced milk in their diet, resulting in inadequate calcium intake (17).
Additionally, no negative effects on bone health were observed in the sparkling water group.
Supplementing hens’ diets with carbonated water for 6 weeks led to increased leg bone strength compared with tap water (19).
Drinking carbonated cola drinks may harm bone health, but plain sparkling water appears to have a neutral or positive effect.
Does it affect heart health?
Research suggests carbonated water may improve heart health, although the evidence is very limited.
One study in 18 postmenopausal women showed that drinking sodium-rich carbonated water decreased LDL (bad) cholesterol, inflammatory markers, and blood sugar.
What’s more, they also experienced an increase in HDL (good) cholesterol (20).
Additionally, the estimated risk of developing heart disease within 10 years was 35% lower among those drinking carbonated water than those drinking the control water.
However, since this was only one small study, significantly more research is needed before any conclusions can be reached.
Carbonated water may have beneficial effects on your cholesterol, inflammation, and blood sugar levels, potentially reducing your risk of heart disease. However, more studies are necessary.
At last there is no perfect research which states that carbonated water is bad for health.
It has no effect on tooth enamel until carbonated water contains sugar element. It greatly improves constipation relief .
Interestingly, a carbonated drink may even enhance digestion by improving swallowing ability and reducing constipation.
