Did you know tea could help boost brain health?

The new study looked at 36 healthy participants over the age of 60 years where the participants were classified into two groups according to how much they drank green tea, oolong tea, and black tea around age 45 and at present.

New research has found evidence to suggest that drinking tea could have a positive effect on the structure of the brain, possibly helping to protect against cognitive decline as people age. The study was led by researchers from the National University of Singapore (NUS) along with the University of Essex and University of Cambridge, UK. The new study looked at 36 healthy participants over the age of 60 years where the participants were classified into two groups according to how much they drank green tea, oolong tea, and black tea around age 45 and at present.

The findings, published in the journal Aging, showed that those who drank green tea, oolong tea, or black tea at least four times a week for about 25 years had better-organised brain regions — which is associated with healthy cognitive function — compared to non-tea drinkers.

“Our results offer the first evidence of positive contribution of tea drinking to brain structure, and suggest that drinking tea regularly has a protective effect against age-related decline in brain organisation,” commented team leader assistant professor Feng Lei.

“Take the analogy of road traffic as an example — consider brain regions as destinations, while the connections between brain regions are roads. When a road system is better organised, the movement of vehicles and passengers is more efficient and uses less resources. Similarly, when the connections between brain regions are more structured, information processing can be performed more efficiently,” explained Feng.

A previous study by Feng also showed that daily tea drinking appears to reduce the risk of cognitive decline in older adults by 50 percent.

“We have shown in our previous studies that tea drinkers had better cognitive function as compared to non-tea drinkers. Our current results relating to brain network indirectly support our previous findings by showing that the positive effects of regular tea drinking are the result of improved brain organisation brought about by preventing disruption to interregional connections,” he added.

Key to a good tea experience

1. Buying fresh whole leaf teas is key to savouring delicate tastes and aromas such that the quality and freshness of tea defines a good tea experience.

Green tea contains compounds such as polyphenol and flavonoids which boosts your immune system. These phytoconstituents act as antimicrobial agents, thereby helping the body fight against infection as well. Moreover, the antioxidants in green tea strengthen and protect the immune system against compounds known as free radicals, which are known to harm living cells and tissues. Regular consumption of green tea flushes out unwanted toxins from the body, thereby helping you have healthy skin.

Though it is well considered that drinking green tea regularly is beneficial for health, it is essential to understand that three to five cups a day is ideal. Over consumption can cause some serious side effects on your body including anemia.
