Green tea is one of the most popular drinks, not only helping to quench thirst but also being concerned about thanks to its benefits for cardiovascular health. Many studies show that the natural compounds in green tea can support cholesterol reduction, improve blood pressure and protect blood vessels.
Supports cardiovascular protection
Green tea contains strong antioxidants, especially catechins. These compounds help reduce inflammation and oxidative stress, two factors that can damage blood vessels over time. When blood vessels are affected, the risk of heart disease and stroke will increase.
According to Dr. Deebanshu Gupta, a cardiologist at Sarvodaya Hospital (India), drinking green tea regularly can support cardiovascular health by protecting blood vessels and improving circulation.
Impact on cholesterol
High cholesterol is the main cause of cardiovascular disease. In which, LDL cholesterol (bad cholesterol) can accumulate in the walls of arteries and cause atherosclerosis.
Some studies show that green tea can help reduce LDL and slightly improve HDL (good cholesterol).
Green tea can help lower LDL cholesterol and support cardiovascular protection," said Dr. Deebanshu Gupta.
However, this effect is usually moderate, and needs to be combined with a healthy diet and lifestyle to be effective.
Affects blood pressure
High blood pressure is a major risk factor for heart disease. Green tea can help blood vessels relax, improve elasticity and support better blood circulation.
Drinking green tea regularly for a long time can help lower blood pressure slightly. Although the reduction is not large, it is still beneficial for the cardiovascular system.
Does it help reduce the risk of heart disease?
Some long-term studies have noted that people who drink green tea regularly have a lower risk of heart disease and stroke. This benefit may be related to improving circulation, reducing inflammation and limiting cholesterol buildup.
In addition, compounds such as catechin and polyphenol also help reduce the oxidation of cholesterol, an important factor in the formation of atherosclerotic plaques.
How much should I drink to be enough?
According to Dr. Deebanshu Gupta, although it is good for health, green tea should not be drunk too much. Adults should drink about 2-3 cups per day. Drinking too much can cause insomnia, heartburn or rapid heartbeat due to caffeine.
Side effects and notes
Green tea is generally safe, but overuse can cause:
Insomnia
Headache
Goosebumps
Rapid heartbeat
Reduced iron absorption
Pregnant women, people with gastroesophageal reflux, arrhythmia or taking cardiovascular medication should be cautious.
In addition, adding more sugar can reduce the benefits of green tea. It is best to drink pure or add lemon.
Notes
Green tea can support cardiovascular health by reducing cholesterol, improving blood pressure and fighting inflammation, but does not replace treatment.
Drinking in moderation, combining healthy eating and exercise will help promote better results.
