Unmilled describes grain that is whole and unground — kernels as harvested, not yet passed through a mill. Unmilled wheat, rice, oats, and other grains keep their bran, germ, and endosperm intact, which protects them in storage: the grain’s own packaging resists pests and oxidation far better than flour does. Whole grains are the starting point for everything from flour milling to brewing and animal feed, and they are also eaten whole — as brown rice, wheat berries, or porridge oats. Nutritionally, unmilled grain retains the fibre, vitamins, and minerals that milling strips away, which is why whole-grain foods are consistently linked to better health.
