Green tea

Green tea comes from the same plant as black tea (Camellia sinensis), but is less processed so it undergoes less oxidation. Loose leaf green tea is used to make tea (what else?) and infusions.
Green tea is rich in antioxidant polyphenols, specifically catechins (notably EGCG) and L-theanine, which provide potent anti-inflammatory, neuroprotective, and metabolism-boosting properties. Regular consumption is linked to improved brain function, enhanced fat burning, reduced cancer risk, and better cardiovascular health.
