Look at the whole cup
A modest home cup with little added sugar differs from several large, heavily sweetened servings. Milk contributes nutrients and energy; added sugar contributes energy.
Notice caffeine and sleep
Tea contains caffeine. Some people tolerate an evening cup while others notice disturbed sleep, anxiety or palpitations. General adult guidance is not a personal target.
Meal timing and iron
Tea can reduce absorption of non-haem iron when taken with food or iron tablets. NHS guidance advises separating tea or coffee from iron-rich meals or supplements, particularly when iron is low.
