A. Example: A 65-year-old woman's one-day recipe is as follows:
Breakfast: one cup of fresh milk (200g), one steamed bun (100g of standardized wheat flour);
Midday meal: rice (round-grained rice, 100g of standardized wheat flour), stir-fried celery with pork (100g of pork shanks, 250g of celery, 10g of soy sauce, 6g of soy oil, 2g of salt). Soy Sauce 10g, Soybean Oil 6g, Salt 2g);
Dinner: Rice (Japonica, Standard I 100g), Lettuce and Tofu Soup (Lettuce 100g, Tofu 100g, Soybean Oil 6g, Salt 2g), Steamed Sea Bass (200g).
Composition table of the food consumed (100g edible portion content), as shown

1. Calculate the subject's energy and nutrient intake for the day based on the recipe above :

2. Dietary energy and various nutrient intakes:
/iknow-pic.cdn.bcebos.com/ d000baa1cd11728bfc9a4555c7fcc3cec3fd2c16 "target="_blank "title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ d000baa1cd11728bfc9a4555c7fcc3cec3fd2c16?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85% 2Fformat%2Cf_auto "esrc="/d000baa1cd11728bfc9a4555c7fcc3cec3fd2c16"/>
From the data, it can be seen that the intake of protein is high, the intake of energy, calcium, and iron basically meets the needs of the vitamins A, B1, and C deficiencies, in particular vitamin C deficiencies most obvious. C deficiency is the most obvious.
3. The ratio of energy supply of the three major nutrients:

The proportion of protein energy supply is high, and that of carbohydrates is on the low side.
4, three meals energy distribution ratio:

This is the first time that I've seen the energy distribution ratio of the three meals. alink">/iknow-pic.cdn.bcebos.com/fd039245d688d43f44ef5985721ed21b0ef43b07?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_ 800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto "esrc="/fd039245d688d43f44ef5985721ed21b0ef43b07"/>
Basically reasonable, with a slightly higher energy intake at dinner and breakfast and lunch slightly lower.
5, the proportion of high-quality protein:
The proportion of high-quality protein = (animal protein + legume protein)/total protein = (6 + 17.9 + 8.1 + 21.6)/83.7 × 100% = 64.0%, greater than 30%, so the intake of high-quality protein is sufficient.
