Boysenberries are recommended for breast cancer
The evidence that boysenberries could be beneficial in fighting breast cancer is derived partly from studies of related berries. Boysenberries are a hybrid of blackberry and raspberry. The fact that boysenberries contain substances that have been shown to be antiproliferative and antioxidant is well established. However, few studies have been performed that directly address the effect of consuming boysenberries on cancer.
Breast cancer-related effects of eating boysenberries
Boysenberries contain ellagic acid, which has been shown to inhibit cancer formation. Boysenberries are also known to have high levels of anthocyanins, which are potent antioxidants. Berry anthocyanins have been shown to inhibit proliferation, apoptosis, inflammation and angiogenesis.
Additional comments
Loganberries are a hybrid cross between between a blackberry and a raspberry.
Note that while we are continually searching for new evidence concerning this food, there is not much interest in it among cancer researchers so few recent studies are available.
