  • Description: Objectives: Postprandial triglycerides (TG), or levels of fat in the blood after a meal, are an independent risk factor for cardiovascular disease (CVD) (1). A clinically feasible test to assess postprandial TG has been developed, known as the Abbreviated Fat Tolerance Test (AFTT) (2), however the impact of coffee consumption prior to an AFTT on postprandial TG is largely unknown. Notably, approximately half of Americans consume at least one cup of coffee before or with breakfast (3), therefore understanding whether coffee intake impacts AFTT results is practical. This study aimed to investigate the effect of coffee consumption prior to an AFTT on postprandial TG, in order to determine whether coffee intake prior to an AFTT affects its validity. Methods: Participants completed 2 randomized AFTTs separated by at least 1 week, but not exceeding 2 weeks. For each AFTT, participants arrived into the laboratory following a 10-hour overnight fast and consumed either 1 cup of water or black coffee. Thirty-minutes later, a baseline blood draw was collected. Immediately following, participants consumed a standardized high-fat shake (73% fat; 9 kcal/kg body mass), vacated the laboratory, and returned 4 hours later for a follow-up blood draw. Results: Six healthy individuals (3 Women, 3 Men; age 21.3 ± 3.2; BMI 25.9 ± 1.6) completed the present study. Two-way ANOVA of TG revealed a significant overall time effect (p = 0.008), but not time x trial interaction (p = 0.87) or overall trial effect (p = 0.27). Absolute change in TG was not different between trials (p = 0.61). Conclusion: In our small study sample, coffee intake prior to an AFTT did not affect postprandial TG. Therefore, coffee intake prior to an AFTT may not affect the validity of the AFTT. Further research should investigate the effects of coffee consumption prior to an AFTT on the validity of the AFTT in a larger, more diverse study population.
