Cereals and their products are an important part of our diet and depend on them on a daily or semi-daily basis due to their high nutritional value, as they are an essential source of energy because they are generally rich in carbohydrates, and a source of fiber and important nutrients such as potassium, phosphorus, magnesium, zinc, and vitamins such as vitamin B group, plant compounds and antioxidants. The research aims to study the demand for grain, bread and oil products in Egypt. And bread in urban and rural areas, where the statistical significance of the estimates obtained was proven, and the coefficient of determination indicates that about 40% and 96% of the change in individual spending on grains and bread is due to changes in the average annual total expenditure per capita in rural and urban areas, respectively. The value of (F) calculated was significant, which means the suitability of the mathematical model for the linear image to study the spending function on grains and bread, and by estimating the spending flexibility of bread and grains in urban and rural areas, it was found that the estimated elasticity for both urban and rural areas amounted to about 0.38 and 0.15, respectively, which is what It means the necessity of this commodity and its importance in relation to the diet, whether in urban or rural areas, as well as in relation to all spending groups, whether low or high.
