The açaí palm tree (Euterpe oleracea Mart.) is mostly native to Brazil, and its fruit, açaí berry, is very popular among physically active individuals. The açaí berry pulp, very pleasing to the taste buds, has gained adepts in Brazil, Europe and USA in recent years, being even considered a "superfruit".1

The açaí berry pulp is rich in anthocyanins, which is reflected on its deep purple color, in addition to other bioactive substances, such as phenolic compounds and flavonoids. Because of its content of such substances, the açaí fruit has been claimed to have a significant pharmacodynamic effect, mainly on the cardiovascular physiology, affecting dyslipidemia and arterial hypertension.

Thus, considering the pharmacodynamic substances and nutritional composition of the açaí berry, understanding the impact of its intake on the lipid profile and blood pressure is necessary.


Nutrition facts

The pulp of the Brazilian açaí has a considerable amount of fats and dietary fibers. When compared to popularly consumed foods, whose cardiovascular benefits have been well established, vitamin E is the nutrient of açaí that stands out. The amount of carbohydrates in the açaí pulp alone, without syrup or any dietary item added, is low (Table 1).

Table 1 Comparison of the nutrition facts of the açaí pulp with servings of foods which display cardiovascular protection

Adapted from the United States Department of Agriculture (USDA).2

The lipid composition of the Brazilian açaí berry is as follows: polyunsaturated fatty acids, 11.1%; monounsaturated fatty acids, 60.2%; and saturated fatty acids, 28.7%.3 Of the monounsaturated fatty acids of the açaí berry, 53.9% are oleic acid,3 a substance found in avocado and olive oil and that can improve the lipid profile.4

Bioactive substances of cardiovascular importance

A significant amount of anthocyanins is present in the açaí berry, which also contains other antioxidant phytochemicals important to the cardiovascular system, such as sterols, mainly beta-sitosterol,3 which, similarly to monounsaturated fats, is also found in olive oil and avocado.4 Beta-sitosterol acts mainly on lipid modulation,4 while anthocyanins act mainly by reducing blood pressure.5

Impact of açaí intake on vascular function

The most important effect of the açaí berry on vascular function is vasodilation, mainly via the anthocyanins. An easily accessible clinical parameter to monitor the açaí effect on vascular function is blood pressure. Despite the expectations, Aqurashi et al.,6 and Udani et al.,7 have not found any improvement in blood pressure deriving from the açaí intake, but their sample was formed by normotensive individuals. However, Aqurashi et al.,6 have reported a 1.4% increase in the flow-mediated dilation of the brachial artery resulting from the intake of 150 g of açaí pulp in an acute test, which reflects a significant improvement in vascular function.

Effect of açaí intake on lipid profile

Despite not finding any improvement in blood pressure, Udani et al. have shown a reduction in total cholesterol from 159 to 142 mg/dL (p < 0.030) in overweight patients consuming 100 g of açaí pulp twice a day for one month, but the other lipid profile parameters showed no change.7 Surprisingly, Sadowska-Krępa et al.,8 have reported an increase in HDL-C levels from 50 to 60 mg/dL in young athletes following the intake of 100 mL/day of açaí juice for six weeks, in addition to a decrease in total cholesterol from 159 to 134 mg/dL, in LDL-C from 90 to 60 mg/dL, and in triglycerides from 94 to 72 mg/dL.

However, a new study has reported that the intake of 200 g/day of açaí pulp for four weeks did not improve the traditional lipid profile parameters of healthy women. Nevertheless, açaí consumption elevated the serum levels of apolipoprotein A1 and the activity of paraoxonase-1, whose molecules are HDL-C precursors. The consumption of açaí improved the transfer of cholesteryl esters to HDL-C, a beneficial biochemical process, because that is an HDL-C function, which captures cholesteryl esters from VLDL-C (reverse cholesterol transport).9

Conclusions/Dietary Management

The açaí intake can be encouraged to patients already adept to its consumption or those who are willing to. However, one should be cautious about overvaluing its claimed effects on lipid profile and vascular function.

Regarding nutrition facts of the açaí, shown in Table 1, ensures its usual use in dietary plans. However, attention should be paid to the foods added to açaí preparations, such as sugar, honey, powder milk, peanut powder.

The açaí pulp is popularly consumed combined with other foods, and some dietary items that can enhance the claimed cardiovascular effects of açaí are cocoa or dark chocolate and oilseeds, such as almonds, chestnuts and walnuts.
