10 Science-Backed Health Benefits of Drinking Green Tea

Sipping Your Way to Wellness: Exploring the Health Benefits of Green Tea

For thousands of years, green tea has been a staple beverage in Eastern culture. And in recent decades, the West has caught on to the many perks this flavorful tea can provide. Beyond just being a comforting warm drink, green tea is brimming with antioxidants and compounds that can benefit your health in numerous ways.

From supporting heart health to enhancing brain function, the potential health benefits of drinking green tea are impressive. Lets explore some of the top research-backed ways that sipping green tea can boost your wellbeing.

1. May Help Protect the Brain

As we age, our brains naturally decline, leading to potential issues like dementia or Alzheimer's disease. Compounds in green tea may help protect the brain against aging. The antioxidants in green tea, especially EGCG, have been shown to boost brain function and improve memory, focus and mood. Green tea may also help reduce risk factors for dementia like high blood pressure, high cholesterol and stroke.

2. Contains Powerful Antioxidants

Antioxidants are substances that reduce oxidative stress in the body and protect cells from damage. Green tea contains high levels of polyphenols, the most potent antioxidants found in plants. The most abundant and beneficial polyphenol is EGCG. Research shows EGCG has anti-inflammatory effects and may lower the risk of chronic diseases like cancer and heart disease.

3. May Promote Heart Health

Heart disease is the leading cause of death worldwide. Compounds in green tea, especially EGCG, have been shown to significantly reduce biomarkers for heart disease, including LDL and total cholesterol levels. Drinking green tea may also lower triglycerides and blood pressure. By protecting artery walls, green tea may prevent plaque buildup and lower heart disease risk.

4. Contains Compounds That Boost Metabolism

Green tea contains small amounts of caffeine as well as epigallocatechin gallate (EGCG), both of which have been shown to boost metabolism. The combination of these compounds gives an added bump to fat burning and may help support weight loss when paired with a healthy diet and exercise.

5. Rich in Antibacterial Compounds

The catechins in green tea, especially EGCG, have natural antibacterial qualities that may help prevent infections and combat bad breath. Compounds in green tea may also inhibit the growth of certain bacteria that cause dental plaque and cavities. More research is needed, but sipping green tea throughout the day may be beneficial for oral health.

6. May Lower Risk of Type 2 Diabetes

Rates of type 2 diabetes have risen globally, but compounds in green tea may help lower risk. Studies link regular green tea consumption with improved insulin sensitivity, lower blood sugar levels and a reduced risk of developing type 2 diabetes. Green tea may also benefit those already diagnosed by helping regulate blood sugar spikes.

7. May Help Protect Skin from Damage

The antioxidants in green tea, especially EGCG, can benefit the health and appearance of your skin when applied topically or consumed. The polyphenols may help reduce sun damage, fight signs of aging, improve skin elasticity, combat acne and reduce redness/inflammation.

8. Linked to Healthier Hair

Green tea's antioxidants may support hair health. EGCG helps hair follicles grow by stimulating the cells. Catechins also prevent hair loss by lowering DHT levels. One study showed that EGCG promoted hair regrowth in mice. While more research is needed, these compounds show promise for healthier hair.

9. Supports Eye Health

Rich in antioxidants that support eye health, green tea may help lower risks of glaucoma and cataracts. The antioxidants fight oxidative damage linked to eye disease. They may also help protect the eyes from harmful UV rays. More research is needed, but green tea appears to boost overall eye health.

10. May Help Reduce Cancer Risk

While more research is needed, many studies link green tea consumption to reduced risk of various cancers including breast, colorectal and prostate cancers. The powerful antioxidants fight free radical damage that can lead to cancer growth. Green tea's anti-inflammatory effects may also lower cancer risk.

To experience the many evidenced-based benefits of green tea, aim to drink 2 to 4 cups per day. Look for high quality, loose leaf or whole leaf green tea for the most antioxidants. Avoid sugary bottled green teas. Brew loose leaves with hot (not boiling) water and steep for 2-3 minutes before drinking.

From supporting brain health to cancer prevention, sipping green tea can serve up an array of health perks. Stay hydrated throughout your day with this refreshing beverage.
