As people age, brain health often becomes a concern, with risks of neurodegenerative diseases like Alzheimer’s and vascular dementia increasing. Researchers and health enthusiasts continually seek foods and beverages that may help prevent cognitive decline. One such potential ally is green tea. A study published in npj Science of Food reveals how this popular beverage offers protective benefits for brain health and beyond.
Green Tea and Brain Health
Green tea has long been celebrated for its weight loss benefits, but its impact extends far beyond the scales. According to the study, green tea may play a significant role in preserving brain health by reducing cerebral white matter lesions—an indicator of small vessel disease linked to cognitive decline, vascular dementia, and Alzheimer’s disease.
White matter lesions occur due to the narrowing of arteries in the brain, often caused by inflammation or the buildup of misfolded proteins, as explained by the American Brain Foundation. These lesions can lead to memory loss, impaired cognitive function, and other neurological issues.
The study also examined the size of the hippocampus, the brain region responsible for memory. Participants who consumed green tea regularly showed fewer white matter lesions and potentially better memory retention than those who drank less.
How Much Green Tea to Drink
The research found that the amount of green tea consumed directly impacts its benefits. Participants who drank approximately 600 ml (around three cups) of green tea daily experienced 3% less brain damage (white matter lesions) compared to those who consumed only 200 ml or less.
Green tea’s effectiveness is attributed to its rich content of antioxidants and anti-inflammatory compounds, particularly epigallocatechin gallate (EGCG). This compound may reduce vascular damage in the brain, offering a natural defence against age-related cognitive decline.
Interestingly, when the study compared the effects of green tea and coffee, it found that coffee did not significantly impact white matter lesions, further emphasizing green tea’s unique benefits.
Other Health Benefits of Green Tea
Green tea isn’t just a brain booster; its health benefits span various aspects of well-being:
1. Aids in Weight Loss:
Green tea is renowned for its metabolism-boosting properties. It contains catechins that help in burning fat and improving physical performance.
2. Supports Heart Health:
Regular consumption of green tea may lower cholesterol levels and reduce the risk of heart disease by improving blood flow and preventing blood clots.
3. Enhances Skin Health:
The antioxidants in green tea help fight oxidative stress, reduce signs of ageing, and may even protect against UV damage.
4. Improves Digestion:
Green tea’s anti-inflammatory properties promote gut health by reducing bloating and improving digestion.
5. Boosts Immunity:
Rich in polyphenols, green tea enhances the body’s immune system, helping ward off infections and illnesses.
6. Reduces Stress and Improves Mood:
Green tea contains L-theanine, an amino acid that promotes relaxation and reduces stress while enhancing focus and mental clarity.
Why You Should Switch To Green Tea
If you’re a coffee lover, this study offers an important reason to consider green tea as a healthier alternative. Its unique properties not only support brain health but also provide other benefits that contribute to overall well-being.
Incorporating three or more cups of green tea into your daily routine could be a simple yet powerful step towards better brain health, improved memory, and a healthier lifestyle. With its antioxidant-rich profile and versatility, green tea proves to be more than just a drink—it’s a lifestyle choice for better health.
