Chewing gum has become a habit for many people, but excessive consumption can easily harm the stomach, and even lead to abdominal discomfort and diarrhea.
Gum is made with natural resin or glycerin resin as its base, mixed with ingredients like syrup and mint, and then pressed into shape. While manufacturers claim that gum can remove dental plaque and bad breath, the fact is that excessive chewing can severely damage the tooth's surface, cause blood vessels in the tongue to rupture, and in severe cases, harm the gums, leading to recession. Most importantly, gum is also very harmful to the digestive system, especially xylitol gum. Its ingredients are considered "cool" in nature and are not easily broken down by stomach enzymes. After entering the intestines, it has a low absorption rate and can easily accumulate on the intestinal wall. Excessive intake can irritate and damage the gastrointestinal tract, easily causing conditions like abdominal discomfort, bloating, borborygmus (stomach rumbling), and diarrhea. People with stomach ailments should avoid chewing too much, as prolonged chewing can reflexively secrete large amounts of stomach acid. Chewing on an empty stomach can also lead to nausea, loss of appetite, and acid reflux. Over the long term, this can lead to the development of stomach ulcers and gastritis.
Currently, gum sold in domestic markets rarely carries proper warnings on its packaging about the xylitol content and the dangers of excessive consumption, so one must rely on self-control. Experts recommend not exceeding 5 pieces per day. It is generally advisable to chew after meals or snacks to help prevent cavities, but each session should not last longer than 15 minutes.
