Tea, green, infusion

Green tea infusion is the liquid made by steeping green tea leaves in water. The figures here describe brewed Sencha Fukujyu and Bancha types, rather than dry tea leaves. It provides mainly water, with trace energy and carbohydrate and small amounts of vitamins and minerals. Per 100g, it contains 0.1g protein, 3mg vitamin C and 20mg potassium.

Vitamin C supports normal collagen formation, while potassium contributes to normal nerve and muscle function. The infusion contains only trace sugars and no fat. Adding sugar, honey or milk changes its nutrient content, so these figures do not describe tea prepared with those additions. Full nutrient figures are provided in the tables below.

About these figures

Values are per 100g of the food as described (Literature sources; Sencha Fukujyu and Banch type). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
