Background: Energy drink consumption is increasing sharply among young adults. While attention has focused on their effects on cardiovascular risk, little is known about their metabolic consequences. We examined the effects of energy drink on insulin secretion.
Methods: We studied 24 healthy subjects, age 29±1 years in a randomized, double-blind, placebo-controlled, crossover study. Caffeine intake history was noted. Subjects randomly consumed a can (473 ml) of commercially available Rockstar energy drink and a placebo drink (with similar sugar content) on 2 separate days. Blood glucose and insulin levels were obtained before and 30 minutes after drink intake, and were compared between caffeine naïve subjects (consuming <160mg of caffeine/day) and regular caffeine users (consuming ≥160mg of caffeine/day).
Results: Energy drink significantly increased insulin secretion compared to placebo. This hyperinsulinemic response was further accentuated in regular caffeine users (Figure). Glucose levels were comparable after energy drink and placebo in both groups. Baseline Homeostasis Model Assessment of Insulin Resistance Index was similar between caffeine naïve and caffeine users, suggesting an absence of underlying insulin resistance.
Conclusions: In young adults, energy drink consumption leads to a greater surge in insulin secretion. This response is more accentuated in regular caffeine users. Energy drinks may impair glucose homeostasis and conceivably contribute to increased cardiac risk.
