In an animal model of esophageal cancer, researchers were able to show that freeze-dried black raspberry powder was able to restore some of the genetic alterations brought about by a chemical carcinogen, N-nitrosomethylbenzylamine.
To conduct this study, Stoner and his colleagues fed rats either a normal diet or a diet containing 5 percent black-raspberry powder. During the third week, half the animals in each diet group were injected three times with a chemical carcinogen, N-nitrosomethylbenzylamine. The animals continued consuming the diets during the week of carcinogen treatment.
After the third week, the researchers examined the animals’ esophageal tissue, thereby capturing …read more
