1. Benefits of Vietnamese green tea
According to dozens of studies, green tea contains many natural antioxidants which can benefit the drinkers as follows:

1.1 Keeps the brain awake
Vietnamese green tea leaves also have a amount of caffeine content, which stimulates nervous excitement [1]. If you are not familiar with the taste of coffee, you can start your day with a hot cup of tea to keep your mind sharp and work more efficiently.
1.2 Helps to improve and protect the brain
L-theanine in green tea has the function of promoting the activity of the inhibitory neurotransmitter GABA to combat anxiety. This acid also increases dopamine and alpha wave production in the brain. Studies show that caffeine and L-theanine can help each other. The combination of these two substances gives a particularly powerful effect in improving brain function.
Catechin compounds in Vietnamese green tea can protect neurons in test tubes and animal models, and demonstrate a potential ability to help reduce the risk of Alzheimer’s disease and Parkinson’s disease [2].
1.3 Helps to lose weight
According to many scientific studies, green tea helps to increase the rate of energy-burning by 4% and the oxidation process by 17%. So, if you are on a diet to lose weight or lose fat, tea is definitely a great aid [3].

1.4 Helps detoxify the body
The majority of Vietnamese green tea consists mainly of water. As a result, it can promote hydration and help meet your daily fluid needs. When you apply the method of cleansing the body by drinking green tea, that means you will drink from 0.7 – 1.4 liters of liquid only from green tea every day.
You should try using tea to purify the body because it contains many natural polyphenol compounds and the antioxidant epigallocatechin-3-gallate (EGCG), which helps to prevent cell damage while preserving youthfulness for your skin.

1.5 Improves breath
There are many things that can help quickly solve bad breath problems, such as mints, gum, and of course, brushing (and tongue scrubbing). But there is another remedy to have a fresh breath is using green tea.
According to “Eat This, Not That!”, people who used green tea as a mouthwash had improved bad breath effectively [4].
1.6 Protect heart health
According to many studies, if cardiovascular patients drink green tea regularly, their mortality will be reduced because the flavonoid compounds in green tea have the ability to prevent oxidation of bad cholesterol LDL which can lead to heart disease and stroke [5].
1.7 Helps to prevent cancer
Preventing cancer is one of the incredible benefits of Vietnamese green tea. People who drank more than 2 cups of green tea per day had a 46% lower risk of cancer than those who didn’t. The active ingredient EGCG in green tea helps inhibit the formation of free radicals and unstable molecules, which can damage healthy cells in the body and cause cancer.
In addition, thanks to the compound EGCG, green tea is considered the most effective antioxidant herb today, helping to slow down the aging of cells and improve the body’s immune system [6].

1.8 Reduces the risk of developing diabetes
Some research indicates that the amount of flavan-3-ols and/or anthocyanins found in green tea can improve blood sugar control and help regulate blood sugar.
Due to its anti-inflammatory properties, green tea is thought to be beneficial for people at risk or diagnosed with type 2 diabetes. Green tea catechins, especially EGCG, may have anti-obesity and anti-obesity effects.[7].
1.9 Helps lower cholesterol
Cholesterol is a fat-like substance found in the cells of the body and having a high cholesterol level is not beneficial for overall health. In fact, high cholesterol can lead to an increased risk of heart disease.
But if you’re a green tea drinker, fear not, because according to a study in the Journal of Nutrition, green tea lowers two types of cholesterol – low-density lipoprotein cholesterol as well as total cholesterol [8].
1.10 Improves skin health
Vietnamese green tea isn’t just a refreshing beverage that helps keep the body hydrated. It also contains a host of other healthy compounds that have anti-inflammatory and anti-aging effects on the skin.
The skin, the largest organ in the human body, is also home to countless problems. Those having psoriasis should try drinking some green tea before making an appointment with a dermatologist. In a study conducted by the Medical University of Georgia (USA), green tea consumption was associated with a reduction in lesions caused by psoriasis [9].

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 [10].

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.
