Wheat, average composition

Wheat offals vary so much in size of particle and in chemical composition in different districts that it is almost impossible to give average data concerning them.1... 

Table 17.1 presents the chemical composition of different vegetable fibers. Compared to the other fibers, wheat straw shows rather low cellulose content, a high lignin composition, but also a high ash content linked to a high silica fraction. Silica is mainly located on the leaves, 12% of ash in the leaves compared to, for example, 6% in the intemodes. Average value is 7-8% of ash in the straw.

Because rice is such a predominant food in the diets of Oriental people, its nutrient composition is relatively more important than the nutritional composition of wheat in Western countries. In most wheat-eating countries, the cereals contribute only 30 to 40% of the average food-caloric consumption, whereas in the rice-eating nations some 60 to 80% of the calories come from rice. Thus, at Eiest, the Oriental diet includes only 20 to 40% vegetables, meats, fish, fruits, and all other foods that could furnish the missing vitamins and minerals. Under such dietary conditions, it is eeisy to understand how the nutrient composition of rice determines the health of those who subsist largely on it...
