Anapsytikophobia (from Greek anapsyktiko, meaning "soft drink") is the fear of soft drinks. Causes of fear include knowing that soft drinks can have negative health effects like obesity and diabetes and worrying that consuming fizzing drinks would put too much gas in the stomach.
Other underlying causes are the fizz of the soda, the flavor, the popping of the can, and lastly the smell. Levels of fear may vary on the type of soda /color as well.
