In recipe compilation, the verification of a single meal is mainly based on the amount of energy. The recipe is compiled as follows. Find out the daily supply of heat energy and nutrients of the object. According to the sex, age and labor intensity of diners, the daily energy supply of 4-year-old girls is 5.9MJ( 1400kcal), and that of protein is 50g.

1, calculate the daily supply of sugar, fat and protein. Protein 50g, heating ratio is 14%. The heating ratio of fat is 30%. Sugar is 56%. Fat: 1400× 30% ÷ 9 = 47 (g). Sugar: 1400× 56% ÷ 4 = 196 (g).

2. Calculate the consumption of staple food and non-staple food. Look up the table and calculate the contents of protein, fat and sugar in the above-mentioned common foods to get the sugar content of sweet potatoes, and then divide it by the sugar content of cereals (75%) to get the food consumption, and take an integer. Calculate the consumption of lean meat and oil in the same way.

3, the formula is rough. On the basis of calculating the consumption of staple food and non-staple food, according to the physiological characteristics of 4-year-old girls, the number of meals and the heat energy point of each meal are determined (according to the arrangement of two meals, the heat energy distribution is breakfast 20%, breakfast 10%, lunch 35%, noon 10% and dinner 25%).

4. After evaluating and adjusting the diet, calculate the amount of energy and nutrients provided, compare it with the reference intake of dietary nutrients of China residents and make appropriate adjustments. Energy intake is 90% normal, protein intake is 80% normal, and other nutrients should reach more than 80% of the standard.
