Tea lovers —did you know that black and green actually come from the same plants? According to Lifehack, different processing produces their varied colors and tastes. Just like green tea, black tea also comes with health benefits. Whether served hot or cold, Lifehack explains that black tea can not only wake you, up but is great for cardiovascular health. It is also packed with antioxidants, which can help fight off illness and lower the risk for certain cancers. Another surprise? When consumed without sugar, black tea is reportedly great for your teeth. Lifehack says that it "prevents plaque build up and kills bacteria that causes cavities."
