Introduction: Theobromine is a naturally occurring substance found in cocoa products. Theobromine may have beneficial cardiovascular effects through various mechanisms. We used the NHANES database to analyze associations between theobromine consumption and cardiovascular health outcomes. Methods: The NHANES database represents a nationally representative population which was used to construct the study population from 1996-2016. We assessed multiple demographic factors and compared differences amongst those who consumed various amounts of theobromine to those who did not. The primary outcome measures were hypertension and lipid profiles. Results: Among 42,038 NHANES survey participants, 37569 and 4469 of the participants reported never consuming theobromine and consuming theobromine, respectively. Table 1 demonstrates baseline characteristics of those reporting no theobromine consumption in comparison to the theobromine consuming participants (100-400md/g and 400-850mg/d). Moderate to high amounts of theobromine consumption was observed in participants who were older with higher BMI and more education and were more likely to be tobacco users in comparison to those with no theobromine consumption (all p-values <0.05). Moderate to high theobromine consumption was also observed to be associated with a higher hemoglobin level, higher LDL cholesterol, lower HDL cholesterol, and prevalence of hypertension (all p-values <0.05). Conclusions: We observed that individuals who consumed moderate to high amounts of theobromine had associated improvements in lipid profile parameters as well as reduced blood pressure. Theobromine may represent a complementary non-pharmacologic supplementation to typical lifestyle modifications to improve cardiovascular outcomes. Further prospective studies are needed to better clarify this potential association.
