Green tea is a type of tea made from leaves that are quickly heated after picking to stop oxidation, preserving a lighter color and fresher, grassy flavor. Because its leaves are less processed than those used for black tea, green tea keeps higher levels of certain antioxidants called catechins, including one called EGCG. These compounds are believed to help protect cells from damage and may support aspects of heart and metabolic health. Green tea also contains caffeine and the amino acid L-theanine, a combination that many people find provides a calm but alert feeling. It can be brewed at lower temperatures than black tea to avoid bitterness and is commonly enjoyed plain, with a squeeze of citrus, or as part of flavored blends. Because it has both caffeine and strong antioxidants, green tea attracts people who want an energy lift along with potential health benefits. Drinking it regularly is linked in some studies to modest improvements in cholesterol, blood sugar control, and weight management, though results vary by person and amount consumed. People who are sensitive to caffeine, are pregnant, or take certain medications should check with a healthcare provider about how much green tea is safe for them. Overall, green tea is a simple beverage choice that offers a distinctive flavor and notable bioactive compounds when consumed as part of a balanced routine.
