18 Sep 2023 --- Sorghum bran has higher levels of essential amino acids and minerals needed for human health and development than whole grain or dehulled sorghum flour, find researchers from the University of Johannesburg. The bran also contained higher levels of crude protein, fat and fiber than whole and dehulled grain. Compared to whole or dehulled grains, sorghum bran is higher in calcium, zinc and potassium. The gluten-free grain contains similar protein, crude fiber, carbohydrates and minerals found in corn, wheat, rice, barley and oats.
