1. Soda water has strong alkalinity, which can make urine alkaline in the kidney, which is beneficial for the kidney to excrete uric acid, but acid-base neutralization reaction will not occur in the blood, so soda water can not change the acidic constitution, and its real value is to alkalize urine and promote uric acid excretion.

2. Soda water that has a healthy effect on the human body mainly refers to water containing "baking soda", that is, sodium bicarbonate. In addition to gout patients, people with excessive gastric acid secretion can also drink more to neutralize gastric acid. However, people with low gastric acid secretion should not drink a lot of soda water, otherwise it will aggravate the lack of gastric acid. Patients with hypertension had better not drink soda water, because soda water contains more sodium, and reducing sodium intake is an important measure to treat hypertension. Healthy people should also not drink soda water in large quantities for a long time, otherwise it will easily lead to excessive sodium in the diet.

3. Pay attention to whether there is "sodium bicarbonate" in the ingredient list when buying soda water. Soda water containing only carbon dioxide can't play a healthy role, and try to choose products with relatively few additives in the ingredient list. If you don't like the taste of soda, you can drink it after refrigeration or ice cooling.
