Coffee and tea are globally beloved beverages, beloved in their own rights. Both contain caffeine and antioxidants linked to lower disease risks; the answer as to which is healthier depends on how it’s prepared; adding extra ingredients such as sugar or creamer can significantly increase calorie counts in your beverage, leading to weight gain or health concerns. It is possible to enjoy both beverages responsibly by opting for unsweetened non-fat milk or stevia extract beverages instead of sweetened versions of these drinks.

Camellia sinensis leaves are used to produce green, oolong and black teas by boiling or steaming them until their constituent parts undergo various levels of fermentation; green tea typically uses leaves without any noticeable levels of fermentation so as to contain minimal levels of caffeine; in comparison, Oolong and Black Tea use leaves which have undergone longer-term fermenting processes which release chemicals with unique flavors and colors, giving each style their signature taste and look.

Green tea and coffee both contain catechins, powerful antioxidants that may provide protection from cancer and boost metabolism to aid with fat burning for weight loss.
