Brewed tea has near zero calories — only 1 kcal per 100 g. A dose-response meta-analysis of 39 cohorts (Chung et al., Adv Nutr 2020) found each daily cup linked to a 4% lower CVD mortality. The calorie cost is essentially zero unless sweetened.
How should I track Wendy's, tea, unsweetened?
Liquid calories from Wendy's, tea, unsweetened are easy to overlook because drinks do not trigger the same fullness signals as solid food. A meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) confirmed that people underreport beverage intake more than solid food. Most people pour 30–50% more than the label serving size without realizing it. Use a kitchen scale to weigh your glass or bottle once — you will know your exact pour going forward. This one calibration step can save you from hundreds of untracked calories per week.
