Scientists have identified a popular beverage that could help reduce wrinkles and slow down the ageing process. A study from Sichuan University in Chengdu, China, suggests that drinking three cups of tea daily may offer significant anti-ageing benefits.
Optimal Tea Consumption for Anti-Ageing
According to the research, consuming around three cups of tea or six to eight grams of tea leaves per day provides the most evident anti-ageing effects. The study involved 5,998 British volunteers aged 37 to 73 and 7,931 Chinese volunteers aged 30 to 79. Participants were asked about their daily tea-drinking habits and the type of tea they preferred, including green, black, yellow, or oolong.
Key Findings on Ageing Markers
The researchers assessed various ageing markers such as cholesterol levels, blood pressure, and body fat percentage to determine the biological age of the volunteers. They found that regular tea consumption was associated with slower biological ageing. The study authors stated: "The exposure-response relationship suggested that consuming around three cups of tea or six to eight grams of tea leaves per day may offer the most evident anti-ageing benefits."
The Role of Polyphenols
The anti-ageing properties of tea are largely attributed to polyphenols, a bioactive compound present in tea. Polyphenols are known to influence the gut microbiome, which can impact age-related changes in metabolism, immunity, and cognitive function. Additionally, tea is rich in antioxidants that protect the skin from damage and decelerate the ageing process.
No Significant Difference Between Tea Types
The researchers did not identify a particular variety of tea as superior. The study found negligible differences in ageing between black tea drinkers in the UK and green tea drinkers in China. Black tea, specifically, is praised for its potential health perks, including supporting gut, heart, and brain health.
Practical Implications
For those looking to incorporate this habit, black tea is widely available. For example, Tesco sells 80 tea bags for £1.35, while Asda offers 50 tea bags for £1.24. While the study highlights the benefits of tea, it is important to note that individual results may vary, and a balanced diet and lifestyle remain key to healthy ageing.
