Should you drink green tea or black tea?

Things to keep in mind when drinking tea.

According to Dr. Huynh Tan Vu, a specialist in Traditional Medicine and lecturer at the Ho Chi Minh City University of Medicine and Pharmacy, drinking tea correctly offers many benefits such as reducing the risk of cancer, preventing and protecting cardiovascular health, combating aging, maintaining healthy bones and joints, improving memory, protecting the liver, preventing complications of diabetes, reducing the risk of infectious diseases, supporting the treatment of asthma, and reducing the risk of tooth decay…

However, there are a few things to keep in mind when drinking tea. It's best to drink hot tea, as its cooling properties can increase phlegm production. The caffeine in tea stimulates the central nervous system, increasing concentration and brain activity. Therefore, drinking tea in the evening can cause difficulty falling asleep and insomnia. It's best to drink tea in the early morning to keep your mind alert and improve work and study performance.

Avoid drinking tea immediately after meals because the tannins can reduce the absorption of iron and other nutrients from food.

People who are taking blood-thinning medication should not drink tea because tea contains vitamin K, which increases the likelihood of blood clotting.

In addition, people with nervous exhaustion, insomnia, and high blood pressure should also limit their tea consumption, as tea contains a lot of caffeine which stimulates the nervous system, increases the burden on the heart, and raises heart rate and blood pressure.

In addition, the tannins in tea have an anti-diarrheal effect, so people with constipation should limit their consumption.
