Background: açaí is the fruit of the palm tree Euterpe oleracea Martius, which is native to the Amazon region. This fruit has been extensively studied due to its potential effects on human health. Studies have also evaluated the potential effect of açaí on the inflammatory response, but there are still few studies that have assessed this property in humans. Objective: in this study we aimed to evaluate the effects of 200 g of açaí pulp consumption per day during four weeks on a rich panel of inflammatory biomarkers. Methods: a prospective nutritional intervention study was conducted on forty apparently healthy women who consumed 200 g of açaí pulp per day for four weeks. A panel of serum inflammatory markers were evaluated before and after the nutritional intervention, namely, cell adhesion molecules (ICAM-1, IVAM-1, P-selectin, MCP-1, and fractalkine), interleukins (IL-1β, IL-6, IL-8, IL-10, and IL-17) and adipokines (adiponectin, leptin, visfatin, and adipsin). The data were analyzed using paired Student's t-test to evaluate the effect of the intervention using PASW Statistics, version 17.0, and a p-value of < 0.05 was considered significant. Results: four weeks of açaí pulp consumption decreased p-selectin, leptin, and visfatin concentrations in the serum of the participating women. Conclusion: these results show that consumption of açaí pulp was able to modulate important biomarkers of the inflammatory process in apparently healthy women.
