Unsweetened tea consumption significantly lowers the risk of all-cause mortality, cancer, and cardiovascular diseases (CVD) compared to sugar-sweetened and artificially sweetened tea. A recent study in Frontiers in Nutrition examined whether the consumption of unsweetened, sugar-sweetened, and artificially sweetened tea influences all-cause mortality and cause-specific mortality.
How does tea consumption affect overall health?
Tea is a popular drink worldwide. More than 2 billion people consume tea daily, and the per capita annual consumption exceeds 100 liters in many countries, including the UK and China.
Tea contains secondary metabolites, such as phenol and flavonoids, with antioxidant properties. Many studies have documented the health benefits of tea, including its protective role against multiple diseases, such as cancer and cardiovascular disease. Moderate tea consumption has also been linked to a reduced risk of all-cause mortality.
Recent studies have shown increased consumption of sugar-sweetened beverages (SSBs) worldwide, leading to higher daily added sugar intake. Some individuals also prefer to have sweet tea as part of their daily intake. Therefore, it is essential to determine whether tea consumed with added sugar or artificial sweeteners affects its overall health benefits.
