Benefits of Green Tea for Health and Wellbeing

Green tea has long been hailed as one of the healthiest beverages, suitable for daily consumption. According to nutrition experts, this tea may help reduce the risk of cardiovascular disease by lowering LDL cholesterol and improving blood circulation. These benefits are largely attributed to the powerful anti-inflammatory properties of green tea.

In addition to its cardiovascular benefits, regular consumption of green tea may also reduce the likelihood of developing certain cancers, including prostate cancer. Green tea is also a valuable ally for those looking to lose weight, thanks to its ability to enhance lipid oxidation.

Furthermore, green tea helps scavenge free radicals, which are a primary cause of oxidative stress. This plays a significant role in preventing diseases associated with insulin insensitivity, such as type 2 diabetes, and various other cellular damages.

Research by Master of Science (M.Sc.) Đặng Thị Hoàng Khuê has revealed that green tea contains numerous beneficial bioactive compounds, including epigallocatechin gallate (EGCG), l-theanine, potassium, iron, calcium, and caffeine. The caffeine content in green tea is considered moderate, at approximately 35mg per 220ml. The l-theanine in green tea contributes to a mild, steady stimulation without spiking blood sugar levels.

Green tea also provides a good amount of vitamin B, along with tannin and folic acid, contributing to a balanced diet. These benefits further solidify green tea’s position as an excellent choice for health-conscious individuals.

Individuals Who Should Refrain from Drinking Green Tea

Despite the numerous health benefits of green tea, it may not be suitable for everyone. According to Doctor Huỳnh Tấn Vũ, who teaches at the University of Medicine and Pharmacy in Ho Chi Minh City, there are some cases where caution is advised when consuming this beverage.

People suffering from constipation should limit their intake of green tea due to the tannin content, which has an astringent effect and could exacerbate the condition. Similarly, those taking blood-thinning medication should refrain from drinking green tea as the vitamin K in the tea may increase blood-clotting ability, leading to potential risks.

Additionally, Doctor Vũ advises that individuals with neurological issues such as neurasthenia, insomnia, or a history of high blood pressure should consume green tea in moderation. This is because green tea contains relatively high levels of caffeine, which can stimulate the nervous system, potentially increasing heart rate and blood pressure, leading to undesirable health consequences.

In conclusion, while green tea offers a plethora of benefits, it is crucial to listen to your body and be aware of your own health conditions to ensure safe and sensible consumption.

Important Considerations for Optimal Benefits

Doctor Dương Ngọc Vân, a specialist in her field, emphasizes that to maximize the benefits of green tea without encountering side effects, individuals should take note of the following points:

– Ideal time to drink: Consume green tea after meals to optimize its health benefits. Avoid drinking tea right after waking up or on an empty stomach, as this may cause stomach discomfort and lead to dizziness or nausea.

– Proper brewing technique: To preserve the flavor and beneficial compounds, use water at approximately 85 degrees Celsius when brewing. Boiling water at 100 degrees Celsius may diminish the taste and nutritional value of green tea.

– Avoid strong infusions: Strong green tea infusions can stimulate the nervous system, leading to insomnia and even increasing the risk of liver toxicity, while also burdening the kidneys during the excretion process.

– Do not mix with prescription medication: If you are undergoing treatment with prescription drugs, refrain from simultaneously consuming green tea to minimize the risk of potential drug interactions.

– Moderate intake: A daily consumption of 100 to 200ml of green tea is recommended to maintain good health.

– Avoid overnight tea: Green tea left overnight may form substances that are not beneficial to health, so it is best to consume it immediately after brewing.

– Test for skin sensitivity: If you plan to use green tea for skincare, test your skin for any allergic reactions to green tea and carefully read the ingredient list of products containing green tea extracts.

Test your skin for allergies before using green tea for skincare purposes.

– Tailoring intake to specific conditions:

+ Individuals with high cholesterol: Drink tea once or twice daily, with 150 to 250mg per serving.

+ Individuals with high blood pressure: Drink tea three times a day, about 2 hours after meals, using 3g of tea per 150ml of water.
