Tequila: what the research actually tested

Almost nothing on this page was measured on tequila. We have no USDA entry for it, and of the eleven sources under it, only one names tequila at all. The rest tested vodka, plain ethanol or liquor as a category. That tells you about alcohol and nothing about agave. The one tequila study, 220 stomach cancer cases in Mexico City, found no link with spirits including tequila. Observational data from 76 cohorts point the other way, linking every 10 g of alcohol a day to 5 percent more gastric cancer risk, with liquor among the drinks where the link was strong. One US standard drink, a 1.5-ounce shot of 40 percent spirits, holds about 14 g. The clearest practical finding is about your stomach. In a trial of 21 adults, peak blood alcohol was 0.064 percent on an empty stomach and 0.020 percent after a full meal. The agave fibre that gets credited to tequila was tested as a 5 to 7.5 g daily supplement for three weeks, so it says nothing about the drink.

What a real portion looks like

• The US National Institute on Alcohol Abuse and Alcoholism defines one standard drink as about 14 g of pure alcohol, which it equates to a 1.5-ounce shot of 40% spirits. — US adults Evidence E source
  14 g alcohol per standard drink

What your body absorbs

• In a randomised crossover trial in 12 adults drinking vodka at 0.5 g alcohol per kg, mixing it with diet cola raised peak breath alcohol to 38.3 against 34.8 ug/100 mL with sugar-sweetened cola. — 12 healthy adults aged 19-64, 8 men and 4 women, morning sessions (n = 12) Evidence B source
  Peak BrAC 38.3 vs 34.8 ug/100 mL, faster gastric half-emptying with diet mixer
• In a four-way randomised crossover trial in 20 healthy adults drinking vodka, eating a food bar or a control meal beforehand cut alcohol absorption by about 30% compared with drinking on an empty stomach. — 20 healthy adults, vodka 0.35 g/kg for men and 0.30 g/kg for women (n = 20) Evidence B source
  About 30% lower relative bioavailability (AUC over the 90-minute measurement window) with food versus fasting
• In a randomised crossover trial in 21 healthy adults given a moderate alcohol dose, peak blood alcohol was 0.064% on an empty stomach and 0.020% after a 635 kcal mixed meal. — 21 overnight-fasted healthy adults, 10 men and 11 women, 0.3-0.35 g alcohol/kg (n = 21) Evidence B source
  Peak BAC 0.064% fasting, 0.047% snack mix, 0.031% test bar, 0.020% full meal
• In a randomised crossover study in 9 healthy men, a small alcohol dose (0.30 g/kg) taken after breakfast gave peak blood alcohol of 13-18 mg/dL against 30.8 mg/dL on an empty stomach, whatever the meal composition. — 9 healthy men, five sessions each (n = 9) Evidence B source
  Peak BAC 16.6, 17.7 and 13.3 mg/dL after fat, carbohydrate and protein meals, 30.8 fasting

Safety, limits and interactions

• A meta-analysis of 76 prospective cohorts linked alcohol to a 5% higher gastric cancer risk per 10 g a day, with a strong association for beer and liquor. — 76 prospective cohorts, 6316385 participants, 32758 gastric cancer cases (n = 6316385) Evidence C source
  5% higher risk per 10 g/day alcohol, strong for beer and liquor
• In pooled cross-sectional data from 16760 US adults without gout or kidney disease, liquor was one of seven foods linked to higher serum urate, although diet as a whole explained 0.3% or less of urate variation. — 16760 US adults of European ancestry without gout or kidney disease (n = 16760) Evidence C source
  Liquor associated with raised serum urate
• In NHANES 2007-2018 data on 29684 US adults, beer (OR 0.76) and wine (OR 0.75) were linked to lower odds of kidney stones, and liquor showed no association. — 29684 US adults including 2840 stone formers (n = 29684) Evidence C source
  Liquor intake not associated with prevalent kidney stones

What people believe that the data does not support

• In a randomised crossover trial in 29 healthy adults, 5 to 7.5 g a day of agave inulin taken as a supplement for 21 days enriched faecal Bifidobacterium 3- to 4-fold. — 29 healthy adults, 21 days per period, 7-day washouts (n = 29) Evidence B source
  Bifidobacterium enriched 3-fold at 5 g and 4-fold at 7.5 g agave inulin per day

Who this works differently for

• In 12 women tested while exclusively breastfeeding and again after weaning, randomly assigned timing showed that pumping breast milk 1 hour before a 0.4 g/kg alcohol dose lowered breath alcohol in both stages. — 12 women exclusively breastfeeding infants aged 3-5 months, retested after lactation ended (n = 12) Evidence B source
  Lower breath alcohol when pumping 1 h before drinking, in both reproductive stages

What is still unknown

• In a Mexico City case-control study of 220 gastric cancer cases and 752 controls, drinking beer or distilled spirits including tequila was not associated with gastric cancer risk. — 220 gastric cancer cases and 752 population controls, Mexico City (n = 972) Evidence C source
  No association for spirits including tequila, OR 2.93 for the highest wine category

The bottom line

If you drink tequila, eat first. Three small randomised trials agree on this. Food before drinking cut how much alcohol reached the blood by about 30 percent over the 90 minutes measured in one of them. In another, a small dose taken after breakfast peaked at 13 to 18 mg/dL against 30.8 mg/dL on an empty stomach, whatever the meal was made of. The mixer matters a little. With vodka, diet cola pushed peak breath alcohol slightly higher than sugared cola, 38.3 against 34.8 ug/100 mL, in 12 people. These trials measured blood and breath alcohol over about 90 minutes. They did not test driving, judgement or harm, and a lower peak is not a reason to drink more. On stomach cancer the evidence disagrees, and you can see why from its shape. The pooled cohorts are large, 76 studies and over six million people, but they are observational, so they show a link and cannot show that alcohol caused it. The tequila study is one city and 220 cases. Neither settles the question for tequila itself, and nobody in our sources has run the study that would. In 16760 US adults without gout or kidney disease, liquor was one of seven foods tied to higher serum urate, although diet as a whole explained 0.3 percent or less of the differences between them. One large survey found no link between liquor and kidney stones. That is an absence of a link, and it is no reason to drink. If you are breastfeeding, one trial in 12 women found that pumping an hour before a drink lowered breath alcohol. It measured the mother's breath. What reaches the baby was outside the study. The study does not tell you whether drinking while breastfeeding is safe. Some questions have no card on this page at all: pregnancy, medicines that interact with alcohol, and liver disease. They matter, and they are questions for your doctor.
