May reduce your risk of cancer

Several laboratory studies have suggested that certain of the substances found in purple potatoes, such as antioxidants, may help prevent or fight cancer, particularly colon and breast cancer. Cancer cells treated with purple potato extract grew more slowly in one research. The extract even induced cancer cell death in certain circumstances.

It's worth noting that previous study has been confined to cancer cells treated in a lab and malignancies in lab rats. As a result, it's unclear if eating purple potatoes would have the same impact on humans. Some of the compounds in purple potatoes may slow the growth of — or even kill — certain cancer cells.
