Green tea has long been known as a healthy drink, but recent studies further affirm its role in protecting the cardiovascular system.
According to Dr. Deebanshu Gupta - Cardiologist at Sarvodaya Hospital, Jalandhar (India) - green tea contains natural compounds that help reduce inflammation and oxidative stress. These are 2 factors closely related to heart disease.
High cholesterol is the leading risk factor for cardiovascular events. Dr. Gupta explains that green tea has the ability to reduce LDL cholesterol (bad type) - a factor that causes plaque buildup in arteries, while also supporting a slight improvement in HDL cholesterol (good type).
A review in the Journal of Nutrition also confirmed that consuming green tea significantly reduces total cholesterol and LDL levels.
In addition, green tea also helps improve blood vessel flexibility, making blood circulation easier. A meta-analysis of 13 clinical trials shows that regular consumption of green tea helps reduce systolic and diastolic blood pressure. Although this effect is more supportive than the main treatment, it still plays an important role in long-term blood pressure control.
The most valuable compound in green tea is catechin, especially EGCG. This is an antioxidant that protects blood vessels from damage, prevents atherosclerosis plaque buildup and supports the production of nitric oxide, helping blood vessels relax.
Dr. Gupta advises adults to drink 2-3 cups of green tea per day to achieve the best benefits. However, excessive consumption can cause side effects due to caffeine levels such as insomnia, headache, rapid heartbeat or stomach acid.
Groups of subjects who need to be cautious when consuming green tea include pregnant women, people with arrhythmia or those taking blood thinners.
To make green tea best for the heart, you should drink pure sugared tea. Adding too much sugar or milk can increase calories and reduce the activity of antioxidants.
In addition, green tea also supports fat metabolism, helping to control weight - a key factor in maintaining a healthy heart. If you experience symptoms such as chest palpitations or dizziness after drinking, consult your doctor for appropriate advice.
