Purple Potatoes and Other Cancer-fighting Foods

Posted 10/20/2015 | By HealthCorps

Potatoes are getting a bad rap these days, with diet trends suggesting a low carb or no carb approach. Peas, corn and potatoes, though vegetables, are typically grouped with grains because they are dense and starchy. Yes, most of us do eat way too many grain-based dishes, and we mostly choose refined or processed grains. We also tend to take healthy foods like potatoes and prepare them with unhealthy cooking techniques, like frying. News bulletin folks, potatoes are very nutritious.

When it comes to vegetables like potatoes you do need to exercise some measure of portion control. Half of a medium potato is equivalent to one serving of bread. It’s also a good idea to leave the skin on (scrub them well) since the skin contains nutrients and fiber. Potatoes come in a variety of colors, and a new study suggests “go purple” if you want to reduce the risk of colon cancer and prevent the spread of this cancer.

The study involved baked purple potatoes and researchers found that these potatoes suppressed the growth of colon cancer tumors in the laboratory setting and in mice, by targeting cancer stem cells. With colon cancer ranked as the second most deadly cancer in the U.S., this study showcases one way to counter and prevent colon cancer.

The researchers chose baked purple potatoes, because potatoes are incredibly popular in general, and baking is a healthy and easy way to prepare potatoes. They wanted to make sure that the baking process did not diminish the anti-cancer properties of the purple potatoes. In the study, consuming one whole baked purple potato (preferably divided between two meals) daily, seemed to be the “target dose” for reaping the cancer-fighting benefits. The resistant starch in the potato, when digested by gut bacteria, is converted to butyric acid which helps to regulate immune function in the gut. This helps to suppress chronic inflammation, often associated with chronic diseases and cancer, and may actually help the cancer cells to self-destruct.

Colors like purple are also associated with a wide range of phytonutrient benefits. So eating a rainbow of colors in your daily diet, from fruits and vegetables, is considered a good way to reduce the risk of a range of diseases including cancers.
