Chandigarh, May 1 —Green tea, long celebrated in traditional medicine across Asia, is now gaining global scientific recognition for its wide-ranging health benefits.
Recent studies and health experts suggest that daily consumption of green tea can contribute to improved heart health, enhanced immunity, better metabolic function, and even reduced risk of chronic diseases.
With its roots tracing back thousands of years in Chinese and Japanese cultures, green tea is made from unoxidized Camellia sinensis leaves and contains a high concentration of antioxidants and polyphenols.
These compounds, particularly catechins such as epigallocatechin gallate (EGCG), are believed to be responsible for most of the beverage’s health-promoting properties.
Medical professionals and nutritionists agree that green tea supports cardiovascular health.
“Green tea contains bioactive compounds that can reduce inflammation and improve the function of the lining of blood vessels, which can lower the risk of heart disease,” said Dr. Sameer Kaul, a Delhi-based cardiologist.
Several clinical trials have shown that regular green tea drinkers experience lower LDL (bad cholesterol) levels, reduced blood pressure, and better regulation of blood sugar — all critical factors in maintaining a healthy heart.
Researchers have also found that the beverage can support the immune system. Rich in antioxidants, green tea has been shown to help the body fend off viral and bacterial infections by neutralizing harmful free radicals.
A 2022 study published in the Journal of Nutritional Biochemistry suggested that the polyphenols in green tea may enhance immune cell activity, especially during periods of stress or seasonal change.
Weight management and metabolic health are among the most widely cited benefits of green tea.
“The combination of caffeine and catechins can aid fat oxidation and improve energy expenditure,” said clinical nutritionist Anjali Mehra.
While green tea alone is not a magic bullet for weight loss, it has been found to complement a healthy diet and exercise regimen, especially in improving fat metabolism.
Beyond physical health, there is growing evidence to support green tea’s role in cognitive well-being.
Some studies indicate that compounds in green tea may help protect against neurodegenerative disorders like Alzheimer’s and Parkinson’s by reducing oxidative stress in brain cells. While conclusive evidence is still developing, researchers remain optimistic.
Green tea also contains L-theanine, an amino acid that promotes relaxation without causing drowsiness. In combination with caffeine, it is known to improve attention, focus, and mood, making it a preferred alternative to coffee for many.
Despite these benefits, health experts caution against overconsumption. Drinking three to four cups a day is generally considered safe for most individuals.
However, excessive intake may lead to issues such as insomnia or stomach discomfort, especially when consumed on an empty stomach or late in the day.
As health trends continue to evolve, green tea remains a time-tested staple that now carries modern scientific validation.
Whether sipped in the quiet of morning or incorporated into a balanced diet, green tea’s potential to support long-term well-being is clearer than ever.
