Celebrating Tea’s Rich Legacy on International Tea Day
Every year on May 21, the world celebrates International Tea Day to recognize tea’s deep-rooted cultural, economic, and health-related value. First introduced in China in 2737 BC, tea has traveled across centuries and continents to become the second most consumed beverage globally, after water.
In India, tea is not just a drink—it’s a tradition. From roadside chai tapris to formal tea ceremonies, India’s connection with tea is profound and emotional. As we celebrate International Tea Day 2025, one question continues to stir debate among health enthusiasts and tea lovers alike: Is green tea healthier than black tea?
To unravel the answer, we consulted Sakshi Singh, Certified Nutritionist at Dietetic Place, Lucknow, who breaks down the health benefits, differences, and best consumption practices of green tea and black tea.
Green Tea vs. Black Tea: What Sets Them Apart?
Though both green tea and black tea come from the same plant—Camellia sinensis, the difference lies in the processing method.
Key Differences in Processing:
- Green Tea: Leaves are quickly steamed or pan-fried to prevent oxidation.
- Black Tea: Leaves are fully oxidized, giving it a darker color and stronger flavor.
This oxidation process impacts the chemical composition, caffeine content, and antioxidant levels, leading to different health benefits.
Green Tea: A Powerhouse of Antioxidants
Green tea is often considered a super drink for health-conscious individuals. Here’s why:
Health Benefits of Green Tea:
- 🟢 Rich in Catechins: Especially EGCG (Epigallocatechin Gallate), known for powerful antioxidant and anti-inflammatory effects.
- 🟢 Aids in Weight Loss: Helps boost metabolism and burn fat, particularly in the abdominal region.
- 🟢 Heart Health: Reduces bad cholesterol (LDL) and improves arterial function.
- 🟢 Brain Booster: Contains L-theanine and moderate caffeine which improve focus, memory, and mood.
- 🟢 Cancer Prevention: Some studies link green tea with a lower risk of breast, prostate, and colorectal cancers.
- 🟢 Supports Skin Health: Protects against UV damage and premature ageing.
Ideal Time to Drink Green Tea:
- Morning or between meals for maximum absorption.
- Avoid late evenings to prevent sleep disturbances.
Black Tea: Bold Taste with Robust Benefits
Black tea, more oxidized than green tea, carries a richer flavor and slightly higher caffeine content.
Health Benefits of Black Tea:
- ⚫ Improves Heart Health: Regular intake linked to reduced risk of heart disease and stroke.

Ideal Time to Drink Black Tea:
- Morning or early afternoon for a natural energy boost.
- Best consumed without milk for maximum antioxidant absorption.
Which Is Healthier: Green Tea or Black Tea?
According to Nutritionist Sakshi Singh, both types of tea offer unique health benefits, but your choice should depend on your health goals and lifestyle.
✅ Choose Green Tea If You:
- Want to lose weight
- Need antioxidant support
- Have a sensitive stomach (lower caffeine)
- Prefer a mild, subtle taste
✅ Choose Black Tea If You:
- Need a mental energy boost
- Like strong, bold flavors

Expert Tips to Maximize Tea’s Health Benefits
🫖 Avoid Sugar: Skip sugar or honey to retain the natural benefits of tea.
🫖 Use Filtered Water: Ensures better flavor and proper infusion of antioxidants.

India’s Role in the Global Tea Landscape
India is the second-largest tea producer in the world, after China. Major tea-producing regions include:
- Assam
- Darjeeling
- Nilgiris
India is also a major exporter of black tea, while green tea production is rapidly increasing due to global demand for healthier options.

Green Tea vs Black Tea: Health Benefits, Antioxidants & Key Differences
Understanding the Basics of Green Tea and Black Tea
Tea lovers around the world often wonder about the differences between green tea and black tea, and more importantly, which one offers greater health benefits. Surprisingly, both teas originate from the same plant – Camellia sinensis. What sets them apart is the processing method, which significantly affects their color, taste, caffeine content, and antioxidant profile.
As more people become health-conscious and turn to natural beverages, the debate between green tea vs black tea continues. So, let’s explore the basics, shared health benefits, and reasons why these teas deserve a place in your daily routine.
🌿 The Origin: One Plant, Two Teas
Both green tea and black tea are made from the Camellia sinensis plant. However, they undergo different processing techniques:
🔄 Green Tea Processing:
- Leaves are steamed or pan-fired quickly after harvesting to prevent oxidation.
- This process helps the leaves retain their green color, mild flavor, and delicate aroma.
- Minimal oxidation means more catechins (antioxidants) remain intact.
🔁 Black Tea Processing:
- Leaves are rolled and fully oxidized, which causes them to turn a dark brown or black.
- The oxidation process gives black tea its strong flavor, rich color, and higher caffeine levels.
- Produces more theaflavins and thearubigins, antioxidants specific to black tea.
💚 Green Tea and Black Tea: Shared Health Benefits
Despite their differences, green tea and black tea share numerous science-backed health benefits due to their high content of polyphenols and flavonoids.
✅ Common Benefits of Green and Black Tea:
- 💪 Rich in Antioxidants: Both are loaded with polyphenols, which neutralize harmful free radicals in the body.
- ❤️ Heart Health: Regular consumption may reduce the risk of heart disease and improve cholesterol levels.
- 🧠 Brain Function Support: Natural caffeine and L-theanine enhance brain activity, mood, and alertness.
- 🩸 Blood Sugar Regulation: Polyphenols may help lower blood sugar levels and improve insulin sensitivity.
- ⚖️ Supports Weight Management: Promotes fat oxidation and helps regulate metabolism.

☕ Black Tea: A Robust Beverage with Powerful Benefits
Black tea offers a stronger taste and higher caffeine content, making it a preferred morning drink for many. Its oxidation process produces unique antioxidants such as theaflavins and thearubigins, which have powerful anti-inflammatory and cholesterol-lowering effects.
⚫ Unique Benefits of Black Tea:
- 💓 Lowers Blood Pressure: Daily intake has been linked to reduced systolic and diastolic blood pressure.
- 🌿 Improves Gut Health: Encourages growth of beneficial gut bacteria, aiding digestion.
- 🧠 Cognitive Support: Caffeine improves alertness, memory, and mental clarity.
