Lipton Brisk: judge it as a sweet drink first

We found no study of Lipton Brisk itself, so the clearest numbers are about sugar. For a generic bottled sweet black iced tea, US survey data gives about 50 g total sugars, 236 calories and 47 mg caffeine in a 16.9 fl oz bottle, recalculated from the 100 g values. FDA sets the Daily Value for added sugars at 50 g. USDA also has an older reference record for Brisk lemon tea at 8.81 g carbohydrate and 21 mg sodium per 3.5 oz (100 g), with no sugar or caffeine figure shown, and the recipe may have changed since. In a randomized crossover study, 8.5 fl oz (250 ml) of black tea drunk with 3.5 oz (100 g) of bread did not change the blood sugar response, while lemon juice lowered the glucose peak by 30%. That study says nothing about the sugar a sweetened bottle adds. The abstract does not say how many people took part, and the lemon in Lipton Brisk is a flavoring, which that study did not test.

How much is actually in it

• Lipton Brisk lemon black tea in USDA reference data carries 8.81 g carbohydrate, 21 mg sodium and 19 mg potassium per 3.5 oz (100 g), with no fat. — USDA SR Legacy Beverages, LIPTON BRISK, tea, black, ready-to-drink, lemon (FDC 175111) (n = 1 record) Evidence E source
  Carbohydrate 8.81 g, sodium 21 mg, potassium 19 mg, phosphorus 26 mg, saturated fat 0 g per 3.5 oz (100 g)

What a real portion looks like

• A 16.9 fl oz bottle of sweetened black iced tea (524 g) carries about 50 g total sugars, 236 calories and 47 mg caffeine in USDA survey data. — USDA FNDDS Tea, iced, bottled, black (92309000), generic, not brand specific (n = 13 measures) Evidence E source
  Per 100 g: 9.49 g total sugars, 45 calories, 9 mg caffeine; 12 fl oz bottle 372 g about 35 g sugars; 20 fl oz bottle 620 g about 59 g sugars

What your body absorbs

• In a crossover RCT, 8.5 fl oz (250 ml) black tea with 100 g bread did not change the glycemic response, while lemon juice cut the glucose peak by 30%. — healthy adult volunteers Evidence B source
  Tea: no effect on glycemic response; lemon juice: peak -30% (p < 0.01), delayed from 41 to 78 min
• In 12 healthy women, tea drunk with an iron meal cut nonheme iron absorption from 5.7% to 3.6%, and waiting 1 hour halved that inhibition. — iron-replete, nonanemic women, mean age 24.8 years (n = 12) Evidence C source
  Fractional iron absorption 5.7% (water), 3.6% (tea with meal), 5.7% (tea 1 h after); inhibition 37.2% vs 18.1%

What it does to your health

• Across 17 cohorts, each daily serving of sugar sweetened beverages was linked to 18% higher type 2 diabetes incidence, and 13% after adjusting for adiposity. — adults without diabetes in 17 prospective cohorts (n = 38,253 cases) Evidence C source
  +18% per serving/day (95% CI 9% to 28%); +13% (6% to 21%) after adiposity adjustment
• Observational data from 14 cohorts with 958,477 people link the highest black tea intake to 11% lower coronary heart disease risk, seen in Europe but not the USA. — 14 cohort studies, 16,990 CHD cases (n = 958477) Evidence C source
  RR 0.89 (95% CI 0.79 to 0.99) highest vs lowest; 0.95 for 2 cups/day, 0.91 for 4 cups/day

Safety, limits and interactions

• FDA set the Daily Value for added sugars at 50 g, no more than 10 percent of 2,000 calories, for adults and children from 4 years. — US adults and children 4 years and older Evidence E source
  DRV 50 g added sugars per day (10 percent of total calories)
• A meta-analysis of 21 studies found mycotoxins in 89.2% of black tea samples, mostly deoxynivalenol and ochratoxin A, less often in high-income countries. — tea samples in 21 studies (n = 21 studies) Evidence D source
  Black tea contamination 89.2% (95% CI 73.9% to 98.3%); aflatoxins 12.4%

What people believe that the data does not support

• The EU refused to authorize the claim that black tea improves endothelium-dependent vasodilation. — EU health claim applicants Evidence E source
  Claim status Non-authorized; 0 authorized EU claims for black tea
• The EU refused to authorize the claim that black tea helps you focus attention. — EU health claim applicants Evidence E source
  Claim status Non-authorized

Who this works differently for

• FDA cites 400 mg caffeine a day as an amount not generally tied to negative effects in most adults, and advises pregnant or breastfeeding people to ask a clinician. — most healthy adults; pregnant, trying to conceive or breastfeeding people Evidence E source
  400 mg/day for most adults; no set figure for pregnancy or breastfeeding
• In a pilot RCT, nursing women drinking 10 fl oz (300 mL) decaffeinated black tea daily for 6 days had no detectable tea catechins in breast milk. — healthy nursing women (n = 18) Evidence B source
  Catechin, epicatechin and conjugates not detected in milk; milk antioxidant capacity unchanged

The bottom line

Across 17 cohorts, each daily serving of a sugar sweetened drink was associated with 18% more type 2 diabetes (95% CI 9% to 28%), and 13% after accounting for body fat. That is observational data on sweet drinks as a group, and sweetened iced tea belongs to it. The tea side is weaker for this product. Pooled cohorts of 958,477 people linked the highest black tea intake to an 11% lower risk of coronary heart disease (relative risk 0.89, 95% CI 0.79 to 0.99), seen in Europe but not in the USA, and those people drank brewed tea. The EU refused to authorize claims that black tea improves blood vessel dilation or helps you focus. On caution, FDA cites 400 mg caffeine a day as an amount not generally linked to negative effects in most adults, and advises people who are pregnant, trying to conceive or breastfeeding to ask their health care provider. In a pilot trial, 18 nursing women drinking 10 fl oz (300 ml) of decaffeinated black tea daily for 6 days had no detectable tea catechins in their milk. Tea also reduces iron absorption from a meal. In 12 women, brewed tea drunk with a meal cut nonheme iron absorption from 5.7% to 3.6%, and drinking it an hour later halved that effect, in a small non-randomized study. A meta-analysis found mycotoxins in 89.2% of black tea leaf samples across 21 studies, which shows presence rather than levels above legal limits. We have no card on children and iced tea.
