Eating purple potatoes has been linked to heart health benefits and lowering inflammation.
Purple potatoes provide antioxidants, especially anthocyanins, fibre, vitamin C and potassium.
Enjoy purple potatoes boiled for potato salad, mashed or roasted with olive oil and rosemary.
 
Colours don't just make food pretty—they can also be a sign of nutritional power. And purple is mighty. This royal shade comes from anthocyanins—disease-fighting antioxidants. The pigment produces red, blue and violet foods—like purple asparagus and purple tomatoes—depending on the type of anthocyanin (there are hundreds). The high antioxidant content in purple sweet potatoes, in particular, fights inflammation and helps slash heart disease and cancer risk. (Source www.eatingwell.com)
