Pina colada: every ingredient measured except the drink

Rum, pineapple, sugar and coconut cream have all been studied. The drink they make has not, and nothing in the corpus carries its name. What it is, before any of that, is an alcoholic drink, and the only official position this page carries is the World Health Organization's: no safe level of alcohol consumption can be named. Coconut fat is the best measured part. Across 16 trials comparing coconut oil with non-tropical vegetable oils for at least two weeks, LDL cholesterol was 10.47 mg/dL higher on coconut oil (95% CI 3.01 to 17.94) and HDL cholesterol 4.00 mg/dL higher (95% CI 2.26 to 5.73). Heterogeneity across those trials was high at 84 percent, and the fat tested was coconut oil rather than the cream poured into a glass. A second meta-analysis pooled seven randomised trials in 515 adults followed from 4 weeks to 2 years. It found HDL cholesterol 3.28 mg/dL higher (95% CI 0.66 to 5.90), body weight 0.24 kg lower (95% CI -0.83 to 0.34) and LDL cholesterol 1.67 mg/dL lower (95% CI -6.93 to 3.59). Two of those three intervals cross zero, and the review graded its own certainty very low with overall risk of bias high.

The numbers, per 100 g

What your body absorbs

• Swapping a sugary mixer for a diet one raised peak breath alcohol from 34.8 to 38.3 micrograms per 100 mL in the same twelve drinkers. — twelve healthy participants (n = 12, 8 male and 4 female) aged 19-64 years, each studied twice after 0.5 g/kg of vodka (n = 12) Evidence B source
  Peak breath alcohol 38.3 (SD 9.45) with the diet mixer against 34.8 (SD 6.82) µg/100 mL, area under the breath ethanol curve 45249.0 against 40439.25 µg·min/L over 180 minutes
• The diet mixer showed a shorter gastric half-emptying time than the sugared one, 100.1 minutes against 110.7, on spreads of SD 35.42 and 66.71. — The same twelve healthy participants, breath samples taken every 15 minutes for 3 hours (n = 12) Evidence B source
  Gastric half-emptying 100.09 (SD 35.42) min with the diet drink against 110.74 (SD 66.71) min with the regular drink, lag phase 49.35 against 46.63 min

What it does to your health

• Coconut fat raised LDL cholesterol by 10.47 mg/dL compared with non-tropical vegetable oils across 16 trials. — Adults in 16 trials that compared coconut oil with other fats for at least 2 weeks (n = 16 trials) Evidence A source
  LDL cholesterol +10.47 mg/dL (95% CI 3.01 to 17.94), HDL cholesterol +4.00 mg/dL (95% CI 2.26 to 5.73)
• Pooling seven randomised trials on 515 adults, coconut oil moved HDL cholesterol by 3.28 mg/dL and left weight and LDL where they were, on very low certainty evidence. — Seven randomised trials, n = 515, 50% females, follow up from 4 weeks to 2 years (n = 515) Evidence A source
  HDL cholesterol +3.28 mg/dL (95% CI 0.66 to 5.90), body weight -0.24 kg (95% CI -0.83 to 0.34), LDL cholesterol -1.67 mg/dL (95% CI -6.93 to 3.59)
• Replacing sugar-sweetened drinks with artificially sweetened ones shifted body weight by 0.73 kg across 14 randomised trials of 3 to 76 weeks, with inconsistent effects on glycaemic and cardiometabolic markers. — Participants of 14 randomised controlled trials lasting 3 to 76 weeks, pooled inside a consensus review (n = 14 trials) Evidence A source
  Body weight -0.73 kg and body fat -0.72% when sugar-sweetened beverages were replaced by artificially sweetened ones

Safety, limits and interactions

• Across 20 systematic reviews of cohorts followed for up to 34 years, heavier drinkers of both sugar-sweetened and artificially sweetened beverages carried higher risk of type 2 diabetes, cardiovascular disease and death. — Cohort participants pooled in 20 systematic reviews, follow-up up to 34 years (n = 20 systematic reviews) Evidence C source
  Direction only: higher risk of type 2 diabetes, cardiovascular disease and mortality, with relative risks for artificially sweetened drinks similar to those for sugar-sweetened ones
• The World Health Organization holds that no safe level of drinking can be named, and that alcohol sits in the same carcinogen group as asbestos and tobacco. — General population, WHO Regional Office for Europe statement of 4 January 2023 Evidence E source
  Position without a threshold dose: risk is described as starting from the first drop

The bottom line

The sugar changes how fast the alcohol arrives, by a little. Twelve healthy people aged 19 to 64 drank 0.5 g of vodka per kilogram of body weight twice. With a diet mixer their peak breath alcohol reached 38.3 micrograms per 100 mL, against 34.8 with the sugared version. That was an open label crossover using cola rather than a blended cream cocktail. The sugared drink appeared to sit in the stomach longer, with a half-emptying time of 110.7 minutes against 100.1. The spread around both numbers was wide, at SD 66.71 and 35.42, and they were read off a nonlinear regression of breath samples rather than measured by imaging, so the ordering is not firm. Changing the mixer buys less than the label suggests. Across 14 randomised trials lasting 3 to 76 weeks, replacing sugar-sweetened beverages with artificially sweetened ones moved body weight by 0.73 kg and body fat by 0.72 percent, with inconsistent effects on glycaemic and cardiometabolic markers. The beverage definition in those trials left alcoholic drinks out altogether. An umbrella review of 20 systematic reviews of cohorts followed up to 34 years found higher intake of both kinds of drink associated with type 2 diabetes, cardiovascular disease and death. The relative risks for the artificially sweetened drinks were similar to those for the sugar-sweetened ones. That is observational and gives direction without a size, and people often move to diet drinks because they are already unwell, which the reviews cannot rule out. The alcohol is the part with an official position and no number attached. The World Health Organization stated on 4 January 2023 that no safe level of alcohol consumption can be named, and that alcohol was classified a Group 1 carcinogen by the International Agency for Research on Cancer decades ago. That is a position about alcohol in general rather than about one glass of this drink. Beyond it, this page has no card about pregnancy, none about any medicine, and none about a serving size, so it cannot tell you what a single pina colada does to you.
