A Brazilian berry popular in health food contains antioxidants that destroyed cultured human cancer cells in a recent University of Florida study, one of the first to investigate the fruit’s purported benefits.

the study showed extracts from acai (ah-SAH’-ee) berries triggered a self-destruct response in up to 86 percent of leukemia cells tested, said Stephen Talcott, an assistant professor with UF’s Institute of Food and Agricultural Sciences.

Acai berries are produced by a palm tree known scientifically as Euterpe oleracea, common in floodplain areas of the Amazon River, Talcott said. When ripe, the berries are dark purple and about the size of a blueberry. They contain a thin layer of edible pulp surrounding a large seed.

Historically, Brazilians have used acai berries to treat digestive disorders and skin conditions, he said. Current marketing efforts by retail merchants and Internet businesses suggest acai products can help consumers lose weight, lower cholesterol and gain energy.

“A lot of claims are being made, but most of them haven’t been tested scientifically,” Talcott said. “We are just beginning to understand the complexity of the acai berry and its health-promoting effects.”

In the current UF study, six different chemical extracts were made from acai fruit pulp, and each extract was prepared in seven concentrations.

Four of the extracts were shown to kill significant numbers of leukemia cells when applied for 24 hours. Depending on the extract and concentration, anywhere from about 35 percent to 86 percent of the cells died.

Brazilian Açaí berries are loaded with antioxidants – 500% more than blueberries and 60% more than pomegranates! In addition to antioxidants, Açaí berries contain omega fatty acids, the good-for-you fats that help protect the heart, lower cholesterol and blood pressure, improve depression, and fight cancer.
