Resumo
The açai fruit (Euterpe oleracea Martius), which is native to the Brazilian Amazon region, was shown to have
high polyphenols and MUFA contents. In this study, we aimed to assess the effects of açai consumption on
plasma lipids, apolipoproteins, the transfer of lipids to HDL (which is a relevant HDL function), and some
biomarkers of redox metabolism. Forty healthy volunteer women aged 24 ± 3 years consumed 200 g of açai
pulp/day for 4 weeks; their clinical variables and blood sample were obtained before and after this period.
Açai pulp consumption did not alter anthropometric parameters, systemic arterial pressure, glucose, insulin
and total, LDL and HDL cholesterol, triglycerides and apolipoprotein (apo) B, but it did increase the concentration
of apo A-I. Açai consumption decreased the ROS, ox-LDL and malondialdehyde while increasing
the activity of antioxidative paraoxonase 1. Overall, the total antioxidant capacity (TAC) was increased.
Regarding the transfer of plasma lipids to HDL, açai consumption increased the transfer of cholesteryl esters
(p ¼ 0.0043) to HDL. Unesterified cholesterol, phospholipids and triglyceride transfers were unaffected. The
increase in apo A-I and the cholesteryl ester transfer to HDL after the açai intake period suggests that an
improvement in the metabolism of this lipoprotein occurred, and it is well known that HDL is protective
against atherosclerosis. Another important finding was the general improvement of the anti-oxidant defences
elicited by açai consumption. Our data indicate that açai has favourable actions on plasma HDL
metabolism and anti-oxidant defence; therefore açai could have a beneficial overall role against atherosclerosis,
and it is a consistently good candidate to consider as a functional food.
