Black rice - Most nutritional rice full of antioxidants with a slight nutty taste and harder texture. I eat mine with tuna, parsley, corn and tomato or any other raw veggies. Nutrional info according to Dr. Axe: White Rice: 6.8 protein / 1.2 iron / 0.6 fiber. Brown rice: 7.9 protein / 2.2 iron / 2.8 fiber. Red rice: 7.0 protein / 5.5 iron / 2.0 fiber. Black rice: 8.5 protein / 3.5 iron / 4.9 fiber and the highest amount of antioxidants of any rice variety.
