2. Side effects of drinking Vietnamese green tea improperly
Aside from the potential Vietnamese green tea benefits, it still has some limitations. If not used correctly, it is likely to experience some unexpected effects as below:
2.1 Upset stomach
You should not drink green tea on an empty stomach because the tannins in tea can cause digestive problems such as diarrhea, constipation, irritable bowel syndrome, and stomach upset.
If you have stomach problems after drinking green tea, adding milk and sugar can reduce these problems.
2.2 Reduced absorption of iron and nutrients
The catechins in Vietnamese green tea can inhibit the body’s absorption of iron from the blood. It may reduce red blood cells that are responsible for transporting oxygen to different organs and areas of the body. When your red blood cell count drops, you can develop anemia.
If you are already anemic, drinking large amounts of green tea can worsen existing anemia. To avoid this, you should limit your green tea intake and eat food containing rich in vitamin C.
2.3 Causes headache and insomnia
Drinking a lot of green tea in the long term can cause mild headaches because green tea contains high caffeine content.
You should not drink green tea before going to bed, because the caffeine in green tea can prevent the brain from producing substances that cause sleepiness, thereby making the brain excessively alert and making you sleepless .
3. How to drink Vietnamese green tea properly
Vietnamese green tea has certain ingredients and medicinal properties. To get the most out of green tea benefits, there are a few things you should keep in mind:
3.1 Brew green tea properly
- Wash tea before using: Wash the tea before using (for fresh tea) and then lightly rinse the tea before brewing (this applies to both dry and fresh tea).
- Brew tea at a moderate temperature: The suitable tea-making temperature is about 80 degrees Celsius, do not brew tea with boiling water. You should also not drink too hot tea, when drinking green tea too hot will damage the inner wall of the stomach, leading to stomach ulcers.
- Do not leave the tea overnight, even in the refrigerator.
- Mix green tea with other herbs: Green tea can be mixed with other herbs to enhance its health benefits.
For example, Vietnamese green tea can be mixed with ginger. Ginger boosts the immune system, relieves pain, and boosts brain function. Mixing green tea with ginger is also an effective weight loss drink.
Or just wait for the tea to cool and add lemon juice and honey and you have a delicious cup of lemon tea. Lemons not only make drinks taste better but also helps the body more easily absorb the antioxidants in green tea.
3.2 Drink the proper & suitable amount of green tea
How many cups of green tea people should drink per day depends on the drinker and the purpose of drinking green tea?
In general, green tea contains caffeine, an ingredient that many doctors recommend no more than 200mg per day, equivalent to about 10-15g Vietnamese green tea per day only. For those who have special purposes such as: want to lose weight and promote a faster metabolism, cure stomach cancer, they can drink more, about 20-25g per day.
3.3 Drink green tea at the proper time
- Do not drink tea with medicine: The substances in green tea when “meeting” with the active ingredients in the drug will create chemical reactions that make the drug less effective and difficult for the body to absorb.
- Do not drink tea right after a meal: Many people have the habit of drinking green tea right after eating, this interferes with the absorption of nutrients into the body. Catechins in green tea may also decrease the absorption of iron from food, increasing the risk of anemia. Ideally, you should maintain a gap between drinking green tea at least 1 hour after lunch.
- Do not drink tea in the evening before going to bed: Green tea water contains quite high caffeine content, which stimulates nerves, makes nerves excited, thereby making it difficult to sleep. Therefore, in the evening, you should drink green tea 1 to 2 hours before bedtime.
