Unlocking the Secrets of Longevity: Three Cups of Tea a Day Could Slow Biological Ageing, Suggests Study.

**Now Chinese researchers have discovered these bioactive substances could help reduce age-related cell damage and help the body's metabolism and immunity system**

In a revelation that may have tea enthusiasts cheering, scientists believe that indulging in three cups of tea daily could be the secret to slowing down biological ageing, according to a recent study. While coffee has taken center stage among the preferences of millennials, the humble cuppa may hold the key to enhanced longevity, as Chinese researchers explore the potential 'anti-ageing' benefits lurking within tea.

The study, conducted by experts at Sichuan University in Chengdu, China, delved into the habits of 5,998 Britons aged 37 to 73 and 7,931 individuals aged 30 to 79 in China. Participants were questioned about their tea consumption habits, including the type of tea consumed (such as green, black, yellow, or oolong) and the average number of cups consumed per day.

The analysis aimed to uncover whether regular tea consumption had any discernible impact on markers of ageing, including blood pressure, cholesterol levels, and body fat percentage. The researchers then calculated the biological age of participants to identify patterns associated with slower ageing.

The findings revealed that individuals who regularly consumed tea exhibited patterns indicative of slower biological ageing. These tea enthusiasts were more likely to be male, follow a healthier diet, and consume alcohol in moderation. Additionally, they were less likely to experience symptoms of insomnia and anxiety.

Publishing their observations in the journal The Lancet Regional Health - Western Pacific, the scientists highlighted an 'exposure-response relationship,' suggesting that consuming approximately three cups of tea or six to eight grams of tea leaves daily could yield the most evident anti-ageing benefits. Moderate tea consumption emerged as a consistent theme among those who experienced the strongest anti-ageing benefits.

Furthermore, the study found that individuals who ceased drinking tea displayed a 'higher increase' in biological ageing acceleration, underscoring the potential long-term impact of regular tea consumption on the ageing process.

The researchers pointed to polyphenols, the primary bioactive substances in tea, as potential contributors to its anti-ageing effects. These compounds have been linked to modulating gut microbiota, with potential implications for regulating age-related changes in immunity, metabolism, and cognitive function.

Despite not differentiating between specific types of tea in their study, the researchers noted that there were no 'substantial differences' in the impact on biological ageing between tea drinkers in the UK and China. This is noteworthy as black tea is more prevalent in the UK, while green tea is the favored choice in China.

Additionally, the study found that the temperature preference of tea, whether piping hot or cooled down, did not significantly influence the observed benefits.

However, it is crucial to note that the study was observational, meaning it cannot definitively establish a causal relationship between tea consumption and slowed biological ageing. The researchers acknowledged a limitation in not recording the size of tea cups used by participants.

In a nation where a staggering 100 million cups of tea are consumed daily, this study may reignite interest in tea's potential health benefits, especially at a time when demand for coffee has surged, particularly among younger demographics. As the scientific community continues to unravel the secrets of longevity, the age-old ritual of sipping tea might just be a small but significant step toward a healthier, longer life.
