Tea, black, infusion, weak

Weak black tea is an infusion of tea leaves in water, strained after brewing. The figures here describe the infusion without added milk or sugar. It provides mainly water, with very small amounts of nutrients. Per 100g, it contains 2 kJ of energy, 0.1g of protein and 18mg of potassium.

Tea contributes to fluid intake, which helps replace water lost by the body. This infusion contains only trace amounts of fat, saturated fat, carbohydrate, sugars and salt. Adding milk or sugar changes its nutrient and energy content, so these figures do not describe tea prepared with those additions. Full nutrient figures are in the tables below.

About these figures
