Bottled aerated soda water：
1、Soda water is weakly alkaline. The internal environment of the human body is also weakly alkaline. The meat and fish we eat every day are acidic foods. Therefore, acid-base balance is required, so soda water is beneficial to health (no history of gastrointestinal disease);
2、Soda water is good for maintaining stomach, because soda water can neutralize stomach acid. But if the stomach acid secretes less, drinking soda water for a long time can also cause harm.
