Strawberries Most Effective in Fighting Against Cancer Cells (press release)
by Mike Adams, the Health Ranger, NaturalNews Editor
Strawberries may be the most
effective of the five most commonly consumed berries at inducing cancer cell
death, according to a recent study conducted at the UCLA Center for Human
Nutrition. The center recently tested extracts of six berries -- strawberries,
raspberries, black raspberries, blueberries, blackberries and cranberries --
to determine their ability to induce apoptosis, a process that enhances the
death of cancer cells.

In one phase of the study, all of the berry extracts exhibited
anti-proliferative effects and did so in a dose-dependent manner. The
strongest strawberry effects were seen against two types of oral cancer cells
and one type of colon cancer cells. A second phase of the experiment measured
their ability to induce programmed cell death (apoptosis) against a
cyclooxygenase (COX)-II expressing enzyme colon cancer cell. The results
showed that the berries were potent inducers of apoptosis in the human colon
cancer cells.
Navindra Seeram, Ph.D., presented the findings of this study at the
International Berry Health Benefits Symposium, June 13-14, 2005.
Strawberries account for 75% of the fresh berry volume sold at retail,
followed by blueberries, raspberries, blackberries and cranberries, in
descending order. Strawberries and other berries contain high levels of the
phytochemicals that are believed to be responsible for the protective effects
of diets high in fruits and vegetables against chronic illnesses such as
cancer, inflammation, heart disease and neurodegenerative diseases.
The investigators concluded that more in vivo studies are warranted to
investigate the impact of berry phytochemicals on human health.
