CH2O ：Directly supply energy Fat Less utilization than CH2O about 10-20% Protein being acid meterials

4 Sport nutrition eg Students in the university/college 4.1 GE: 3000 - 6000kcal/d 4.2 Ratio of Energy: Carb:Prot:Fat = 4：1：1

4.3 Important of CH2O CH2O in Dietary Menu is very important 55-60%, 9-10g/kg BW such as cereals, fruits and vegetables CH2O be divided into ：Keeping blood glucose level Especially after sports Supporting enough energy to brain and heart
