Healthful drinks are beverages that provide essential nutrients and minerals to the body. TEA, TONIC, and green TEA are all examples of healthful drinks. TEA is a beverage made from the leaves of the Camellia sinensis plant and is usually served hot or iced. TONIC is a carbonated beverage that is often flavored with quinine and other ingredients. Green TEA is a type of TEA made from unfermented leaves of the Camellia sinensis plant and is known for its high antioxidant content. All three of these drinks are considered healthful and can provide numerous health benefits.
