Whole wheat Atta is made by stone grinding, a process that imparts a characteristic aroma and taste to Rotis. High bran content of true wholewheat atta makes it a fiber-rich food. This helps to regulate digestion, blood sugar, cholesterol, obesity, skin quality as well have other health benefits. The temperatures attained in a chakki (stone mill or grinder), produced by friction, are of the order of 110-125° Celsius. At such high temperatures, the carotenes present in the bran tend to exude the characteristic roasty smell, and contribute to the golden color of the atta. \
