Superfood: Acai Berry
I ran across this article and thought it would be good to share with our readers.
Brazilian berry destroys cancer cells in lab, UF study shows
GAINESVILLE, Fla. — 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.
Published today in the Journal of Agricultural and Food Chemistry,
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 already considered one of the richest fruit
sources of antioxidants,” Talcott said. “This study was an important
step toward learning what people may gain from using beverages, dietary supplements
or other products made with the berries.”
He cautioned that the study, funded by UF sources, was not intended to show whether
compounds found in acai berries could prevent leukemia in people.
“This was only a cell-culture model and we don’t want to give anyone false hope,” Talcott
said. “We are encouraged by the findings, however. Compounds that show good
activity against cancer cells in a model system are most likely to have beneficial effects
in our bodies.”
Other fruits, including grapes, guavas and mangoes, contain antioxidants shown to kill
cancer cells in similar studies, he said. Experts are uncertain how much effect antioxidants
have on cancer cells in the human body, because factors such as nutrient absorption,
metabolism and the influence of other biochemical processes may influence the
antioxidants’ chemical activity.
Another UF study, slated to conclude in 2006, will investigate the effects of acai’s antioxidants
on healthy human subjects, Talcott said. The study will determine how well the
compounds are absorbed into the blood, and how they may affect blood pressure, cholesterol
levels and related health indicators. So far, only fundamental research has been
done on acai berries, which contain at least 50 to 75 as-yet unidentified compounds.
“One reason so little is known about acai berries is that they’re perishable and are traditionally
used immediately after picking,” he said. “Products made with processed acai
berries have only been available for about five years, so researchers in many parts of
the world have had little or no opportunity to study them.”
Talcott said UF is one of the first institutions outside Brazil with personnel studying acai
berries. Besides Talcott, UF’s acai research team includes Susan Percival, a professor
with the food science and human nutrition department, David Del Pozo-Insfran, a doc-

toral student with the department and Susanne Mertens-Talcott, a postdoctoral associate
with the pharmaceutics department of UF’s College of Pharmacy.
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.
The UF study demonstrates that research on foods not commonly consumed in the
United States is important, because it may lead to unexpected discoveries, said Joshua
Bomser, an assistant professor of molecular nutrition and functional foods at The Ohio
State University in Columbus, Ohio.
But familiar produce items have plenty of health-giving qualities, he said.
“Increased consumption of fruits and vegetables is associated with decreased risk for
many diseases, including heart disease and cancer,” said Bomser, who researches the
effects of diet on chronic diseases. “Getting at least five servings a day of these items is
still a good recommendation for promoting optimal health.”

Thanks for all the great info about acai beans. I've seen them offered as a boost in smoothies, but not sure if it's the real stuff or not.
I also love those charro beans too! Anything "beans" that's crock pot quick is on my list!
it is the wonderful super food with huge number of benefits,,,,, i really like acai
