For millions of people, tea is an essential part of daily life.
But when it comes to choosing between green and black tea, which one offers greater health benefits? In 2021 alone, Americans consumed nearly 84 billion servings of tea—84% of which was black tea and 15% green tea—keeping this debate alive. To clarify the differences, nutritionists have analyzed the benefits of each.
Nutritional Comparison
Both green and black tea originate from the Camellia sinensis plant, but their processing methods set them apart. Green tea undergoes minimal processing, preserving a high concentration of antioxidants known as catechins. In contrast, black tea is oxidized, reducing catechin levels but creating other beneficial compounds like theaflavins and thearubigins.
