Grape Seed Extracts for Skin Cancer
Skin cancer, the most common cancer in Americans, occurs because of the uncontrolled growth of abnormal skin cells. It is caused mainly by excessive sun exposure and sunburn, although a person’s complexion, family health history, and age are also strong contributing factors. It is classified into 2 types: melanoma and nonmelanoma.
In May 2007, based on the results of a study conducted by researchers from the University of Alabama in Birmingham, it was suggested that chemicals contained in grape seeds may help ward off skin cancer. The study used a group of mice, divided into 2 groups. Though both mice groups were given the standard diet, 1 group was given an additional supplement in the form of grape seed proanthocyanidins (GSPs). The mice with GSP supplementation showed a fewer number of tumors as compared to the mice from the control group. If there were occurrences of tumors in the GSP-supplemented mice, the number was lower by at least 78% than those found in the other group.
These findings suggested that if taken regularly as a dietary supplement, GSPs can be beneficial in the prevention of skin cancer. Its antioxidant characteristics and its ability to restrain immune system suppression due to ultraviolet light are what contribute to its positive action against skin cancer.
Though the benefits of GSPs in skin cancer prevention has been affirmed, there is still a need to do further studies with regard to preventive measures and strategies.
