Tea, especially traditional teas like green tea, black tea, oolong tea, and herbal tea, can have many positive effects on the digestive system.
Here are some of the key benefits of tea for the digestive system:
1. Aids digestion:
- Ginger tea: Ginger tea is well known for its digestive benefits. Ginger helps stimulate the production of gastric juices, which aids in the digestion of food, reducing bloating and indigestion. It also has a soothing effect on the stomach and reduces nausea.
- Peppermint tea: Peppermint tea has a soothing effect on the digestive tract, helping to reduce stomach cramps, reduce bloating and improve intestinal gas flow. Peppermint can also help relieve symptoms of functional gastrointestinal disorders such as irritable bowel syndrome (IBS).
- Chamomile tea: Chamomile tea has a relaxing and soothing effect, which helps reduce inflammation and irritation in the stomach. It can help relieve symptoms of indigestion and heartburn.
2. Reduce inflammation and protect the stomach lining:
- Green tea: Green tea contains a lot of catechins, especially EGCG (epigallocatechin gallate), which has anti-inflammatory effects and protects the stomach lining from damage caused by free radicals. Some studies also show that green tea can help reduce the risk of stomach-related diseases such as stomach ulcers.
- Black tea: Black tea also has the same antioxidant compounds as green tea, which help reduce inflammation and protect the digestive tract. However, black tea may contain more caffeine, which can irritate the stomach if consumed in excess.
3. Enhance liver function: Green tea: Green tea is not only good for the stomach but also helps improve liver function. The antioxidants in green tea can help protect the liver from damage and support the detoxification process. Many studies have shown that green tea can help reduce fat in the liver and protect the liver from diseases such as fatty liver.
4. Support digestion after meals: Black tea and oolong tea: These teas can help promote digestion after meals, especially in breaking down fats. Black tea also has the ability to reduce blood sugar, helping the digestive system process food more effectively.
5. Enhance intestinal motility: Herbal teas (such as lotus tea, licorice tea): Some herbal teas help stimulate intestinal motility, support easier excretion and help solve problems such as constipation. For example, licorice tea can help soothe the digestive tract and stimulate the digestive system to work better.
6. Reduces uncomfortable symptoms of digestive disorders: Chamomile tea and peppermint tea help relieve symptoms of digestive disorders such as bloating, gas, flatulence or nausea. This herbal tea has the effect of relaxing the muscles in the digestive tract and helps reduce stress on the digestive system.
7. Reduces the risk of constipation: Lotus tea and some other herbal teas have the effect of promoting the excretion process and supporting the digestive system, reducing the symptoms of constipation. They help soften stools and make them easier to pass.
8. Diuretic effect: Some types of tea such as pineapple tea or bitter melon tea have diuretic effects, helping to cleanse the body and support the digestive process by reducing water retention and reducing pressure on the kidneys.
A few notes:
- Although tea has many benefits for the digestive system, drinking too much caffeinated tea (such as black or green tea) can irritate the stomach, leading to heartburn or stomach pain in some people.
- It is also important to note that drinking tea immediately after a meal can affect the absorption of iron and protein from food, as certain compounds in tea can reduce the absorption of these substances.
Tea can provide many benefits for the digestive system, from aiding digestion, reducing inflammation, to enhancing liver function and soothing digestive symptoms. However, it is also necessary to drink tea reasonably and pay attention to the interaction between tea and other foods to achieve the best effect on digestive health.
