Increasing the intake of purple potatoes & other colorful fruits and vegetables could lower the risk of colon cancer and many other diseases, according to the results of a new study.
In a study of pigs, researchers found that supplementing a high-calorie diet (HCD) with purple potatoes led to a reduction in levels of interleukin-6 (IL-6) – a pro-inflammatory protein that studieshave shown can promote colon cancer – in the colon.

Study co-author Jairam K.P. Vanamala, a professor of food sciences at Pennsylvania State University in State College, and colleagues say their results support previous research that claims that plant-based diets are linked to lower colon cancer risk.
The researchers recently reported their findings in The Journal of Nutritional Biochemistry.
According to the American Cancer Society, there will be 95,520 new cases of colon cancer diagnosed in the United States this year.
If Caught initial, the 5-year survival rate for colon cancer is Surround 92 percent. For patients whose colon cancer has metastasized, or spread to other parts of the body full, 5-year survival stands at Surround 11 percent.
Studies have suggested that dietary changes – such as reducing meat intake and increasing the consumption of whole body grains, fruits, And vegetables – can help to lower the risk of colon cancer.
Prof. Vanamala and http://radiologyebook.net/video-medical team expand on these findings by shedding light Above how brightly colored fruits And vegetables might contribute to better colonic health.
"What we are learning is that food is a double-edge sword – it may promote disease, but it may While help prevent chronic diseases, like colon cancer," says Prof. Vanamala. "What You don't know is, 'how does this food work Above the molecular level?' This study is a step in that direction."
Purple potatoes & pigs
The researchers came to their findings By means of feeding pigs one of three diets for 13 weeks: an HCD, an HCD supplemented with purple potatoes (raw or baked), And a standard diet (the control diet).
As with Remove many colorful fruits and vegetables, purple potatoes Cover beneficial nutrients at significantly as possible levels than their white-fleshed counterparts.
"Specifically, purple-fleshed potatoes are rich in phenolic acids & anthocyanins," the researchers note. "[…] white potatoes may have helpful compounds, but the purple potatoes have much greater concentrations of these anti-inflammatory, antioxidant compounds." Previous studies have shown that these compounds have anti-cancer properties.
