Carbonated drinks are beverages that contain dissolved carbon dioxide. The dissolution of CO2 in a liquid gives rise to fizz or effervescence. The process usually involves carbon dioxide under high pressure. When the pressure is removed, the carbon dioxide is released from the solution as small bubbles, which causes the solution to become effervescent, or fizzy. A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. Carbon dioxide is only weakly soluble in water, therefore it separates into a gas when the pressure is released.
Carbonated beverages are prepared by mixing the flavored syrup with carbonated water, both chilled. Carbonation levels range up to 5 volumes of CO2 per liquid volume. Ginger ale, colas, and related drinks are carbonated with 3.5 volumes. Other drinks, often fruity ones, are carbonated less.
4 Health Benefit of Sparkling Water
1) Sparkling Water Keeps You Hydrated
Many people think that drinking carbonated or sparkling water can dehydrate you, but health experts say this is just a myth. Drinking sparkling water offers the same thirst-quenching benefits of plain water, and even more healthy advantages if the sparkling water is filtered. Filtered water removes organic compounds, contaminants, and harmful chemicals so you can ensure the water you're drinking is clean and healthy.
2) Drinking Carbonated Water May Aid Digestion
If you suffer from frequent indigestion, dyspepsia, or just have an upset stomach on occasion, drinking a tall glass of filtered, sparkling water could help tame your tummy troubles. According to a study published in the European Journal of Gastroenterology and Hepatology, patients who had a predisposition to gallstone formation, dyspepsia or constipation showed that their gallbladder issues, overall digestion, and constipation problems all improved after drinking sparkling water for two weeks.
3) Sparkling Water Keeps You Feeling Full
Those tiny carbonation bubbles in a glass of sparkling water may offer a mighty punch when it comes to controlling your weight or even losing some extra pounds. The carbon dioxide in sparkling water allows fizzy bubbles to fill your stomach and trick your brain into feeling full, which means you will probably eat less. A 2012 study published in the Journal of Nutritional Science and Vitaminology showed that participants who drank sparkling water on an empty stomach shared that they felt fuller than when they drank still water. To avoid overeating during meals, try drinking two eight-ounce glasses of filtered, sparkling water 30 minutes before you eat.
4) Drinking Sparkling Water Can Increase Productivity
Scientists have long touted that even mild dehydration during the workday can have a significant impact on employee productivity because our brains just don't work as well without replenishing the water we have lost. According to a 2014 study published in the Journal of Cerebral Blood Flow & Metabolism, researchers found that mild dehydration (5 percent of our body weight) can actually disrupt blood vessels in our brains; reducing cognitive performance -- especially in terms of reaction time, paying attention, and our short-term memory.
