Green Tea Benefits for Your Health
Feb
Green Tea Benefits for Your Health: It is commonly consumed as a beverage or dietary supplement to help alleviate digestive issues, headaches, boost alertness, and support weight loss.
Despite being rich in nutrients, vitamins, and minerals, green tea itself contains almost no calories. A small amount of minerals such as calcium, iron, and potassium can be found in it. Let’s explore the key benefits of green tea below.
1. Contains Plant-Based Antioxidants
Green tea is rich in polyphenols, especially catechins, which are natural antioxidants that protect cells and provide other health benefits.
The most common catechin is epigallocatechin-3-gallate (EGCG), which has shown potential in supporting cardiovascular and metabolic health.
2. Boosts Brain Function
A 2007 study revealed that caffeine and L-theanine in green tea can improve cognition, mood, and brain function.
In 2020, research found that green tea reduced the risk of cognitive decline by 64% in older adults.
3. Enhances Fat Burning
A 2022 review found that green tea boosts metabolism during aerobic and strength training exercises. However, its effect on weight loss remains minimal.
4. May Help Prevent Cancer
Some studies link green tea consumption to a lower risk of cancers such as lung and ovarian cancer.
However, there is no conclusive evidence regarding its overall effect on cancer prevention.
5. Protects the Brain Against Aging
A 2020 study indicated that EGCG and L-theanine in green tea might reduce Alzheimer’s-related symptoms in individuals without cognitive issues.
On the other hand, a 2023 report suggested that drinking more than 13 cups per day could increase the risk of Alzheimer’s.
6. Supports Heart Health
Regular green tea consumption may reduce risk factors for cardiovascular disease, such as high blood pressure and lipid levels.
Further research is needed to confirm these effects.
7. May Help Prevent Type 2 Diabetes
A 2020 study found green tea could lower fasting blood sugar in the short term, though it had no long-term effects on blood sugar or insulin levels.
In 2021, a study in Chinese adults with type 2 diabetes observed a 10% lower mortality rate among those who drank green tea daily.
8. Aids Weight Management
Research from 2022 indicated that drinking four cups of green tea daily could reduce abdominal obesity risk by 44% in women, though it does not affect appetite hormones.
9. Reduces Stroke Risk
A 13-year study involving 82,000 Japanese participants found that high green tea consumption lowered stroke risk, especially for those drinking four cups daily.
10. May Increase Lifespan
Green tea contains compounds that may help reduce cancer risks and promote heart health.
Research shows those who drink more than five cups a day have a lower mortality rate than those consuming fewer than one cup daily.
A 2021 study revealed that drinking seven cups daily reduced mortality risks by 62%, even in individuals with heart disease.
11. Eases Anxiety and Stress
Green tea contains L-theanine, an amino acid that reduces anxiety and stress.
A 2017 study found that students who drank green tea had lower stress levels than those given a placebo.
12. Supports Skin Health
A pilot study showed that green tea extract (containing 40% catechins) could prevent skin redness and inflammation caused by UV exposure.
Other research found green tea extracts possess antibacterial, anti-inflammatory, and antioxidant properties, helping reduce acne and skin infections.
13. Green Tea Benefits for Your Health: Lowers Cholesterol
A 2020 study concluded that green tea significantly reduced total and LDL (“bad”) cholesterol in people with moderate or high body weight.
Larger studies are needed to confirm these findings.
