A recent Chinese study discovered that drinking tea daily may assist in slowing signs of aging and reducing skin wrinkles – all this thanks to the content of compounds rich in antioxidants. According to the study, three cups of tea a day is the optimal amount to enjoy the anti-aging benefits of tea, especially considering its potential role in supporting heart, brain, and gut health.
The study was conducted by researchers from Sichuan University in Chengdu, China, where data was collected from a large sample of 5,998 British participants aged 37 to 73, and 7,931 Chinese participants aged 30 to 79. The researchers relied on an analysis of the participants’ daily tea drinking habits and also conducted a comparison between the types of tea – green, black, yellow, or oolong, alongside tracking metrics such as blood pressure, cholesterol, and body fat percentage.
The research team noted that a daily consumption of an amount equivalent to six to eight grams of tea leaves – usually about three cups of tea – may have clear effects in slowing down aging. The researchers attributed these benefits to the polyphenols found in tea, which are essential compounds that help support gut health and improve metabolic functions, the immune system, and cognitive abilities.
The study also showed that tea contains antioxidants that may protect the skin from damage caused by environmental factors, which is reflected in the health and appearance of the skin. The study did not identify a specific type of tea as the most effective, and the temperature at which the tea was consumed did not affect the results either, but it did note minor differences between black tea consumers in the UK and green tea consumers in China.
Behind the effect of polyphenols
Polyphenols is a collective name for a group of organic compounds with a similar chemical structure, which are naturally found in plant-based foods, and mainly in fruits and vegetables. Beyond making meals tastier, polyphenols are packed with antioxidants, which help protect cells in the body from damage caused by free radicals. By neutralizing them, polyphenols play a key role in maintaining body health and its proper functioning.
Studies indicate that these compounds can reduce inflammation, improve heart health, and even lower the risk of certain types of cancer. In addition, there is evidence that they improve brain function and help maintain sharp memory as one ages.
The different types of tea in the world
Tea is not a beverage that automatically suits everyone. There are different types of tea, each offering unique health benefits through its unique processing methods:
Green tea is known for its high antioxidant content, and it also contains many polyphenols. Regular consumption of green tea helps improve heart health, assist in weight loss, and reduce the risk of chronic diseases such as diabetes.
Black tea is not only tasty, but also rich in flavonoids that improve heart health. The consumption of black tea helps lower the risk of stroke, lower blood pressure, and reduce LDL cholesterol levels in the blood.
White tea, produced from the young leaves and buds of the Camellia sinensis plant, is known as a tea with a high amount of antioxidants. It helps improve skin health, supports weight loss – and it also contains less caffeine than other types.
Oolong tea is located between green and black tea in terms of oxidation. It is known for its diverse flavors, and it also helps increase metabolism and assists in weight management.
Not only slows down aging
In addition to the potential slowing of aging, tea also helps maintain mental alertness thanks to its caffeine content. The unique blend of caffeine and the amino acid L-theanine in tea improves attention and memory and causes faster reaction times, which leads to improved mental performance.
It is worth noting that tea, and especially green tea, also supports dental health. It is rich in fluoride, strengthens tooth enamel, and reduces the risk of cavities. The polyphenols and catechins found in tea also fight the bacteria responsible for tooth decay and gum disease.
