One of the fastest growing trends in 2017 will be purple-coloured food, according to Whole Foods. Some already becoming popular are purple cauliflower, black rice, acai berries, purple sweet potatoes, purple corn and cereal.
The colour is telling of the antioxidant quality of the food. The National Health and Nutrition Examination Survey found an association between eating purple fruit and vegetables, and a reduced risk of heart disease and low cholesterol.
Purple foods have also been credited with the ability to reduce cancer-related activity in the body, help the heart and the liver, reduce stomach ulcers and prevent urinary tract infections.
