Ohio State University research strongly suggests that a mix of preventative agents, such as those
found in concentrated black raspberries, may more effectively inhibit cancer
development than single agents aimed at shutting down a particular gene. Researchers
at the Ohio State
University Comprehensive Cancer Center examined the effect of freeze-dried
black raspberries on genes altered by a chemical carcinogen in an animal model
of esophageal cancer.
The
carcinogen affected the activity of some 2,200 genes in the animals’ esophagus
in only one week, but 460 of those genes were restored to normal activity in
animals that consumed freeze-dried black raspberry powder as part of their diet
during the exposure.
