As a food material rice is nutritious and easily digestible. In comparison with other grains it is poor in nitrogenous material and fat, and correspondingly rich in non-nitrogenous substances or carbohydrates.
Cleaned rice contains 79% carbohydrate. Carbohydrate of rice is predominantly starch, with small portions of pentosans, hemicelluloses and sugars. As in most starches, both of the major components (amylase and amylopectin) occur generally in rice starch.
Sugars comprise some 0.3 to 0.5% of white rice and about 0.6 to 1.4%b of brown rice. Reducing sugars (maltose) increase and non-reducing sugars (sucrose) decrease during storage. The degradation of carbohydrates to CO2 is usually very small, but it may become significant at moisture more than 14%.
The changes of free carbohydrate content are greatly influenced by temperature. Maillard’s browning reaction between free carbohydrates and free amino acids may play a significant role in CO2 formation.
Fiber is a carbohydrate and is also a carbohydrate blocker. In other words, it slows down the absorption of digestible carbohydrates.

Nutrition is a scientific discipline that encompasses a structured body of knowledge. It includes various fields such as clinical nutrition, community nutrition, public health, food policy, and food science. At its core, nutrition is the study of how the body utilizes food. It is essential to life. Understanding nutrition enables us to make better dietary choices by determining the necessary nutrient intake, identifying optimal food sources, and recognizing beneficial or harmful food components.
