* * 5. The energy supply ratio of nutrients in the three major productive forces is protein = 77.5× 4/2100 =14.7% (10-15%) and fat = 57.4× 9/2/kloc. Conclusion: The diet is complete, the energy and most nutrients are sufficient, and the proportion of nutrients in the three major productivity is appropriate. Considering the supply of high-quality protein, the energy distribution of three meals is reasonable, which is a scientific and reasonable nutritional recipe. It should be noted that this evaluation is mainly based on the status of macro-nutrients. In practical work, it is necessary to evaluate the suitability of various micro-nutrients, and detect the nutritional status indicators such as weight changes of diners to adjust recipes. Dietary nutrition management software automatically selects food types, automatically compiles alternative recipes, calculates the consumption of various foods and automatically allocates them to meals reasonably. Analyze and calculate the nutritional components of the diet, adjust and analyze the food structure of the diet according to the results, and calculate and analyze the intake of various nutrients, energy and food sources in protein. Comprehensive evaluation of individual and group dietary nutrition. Special nutrition catering or nutrition management software automatically selects food types, automatically compiles recipes for generations, calculates the consumption of various foods and automatically and reasonably allocates them to meals. Analyze and calculate the nutritional components of the diet, adjust and analyze the food structure of the diet according to the results, and calculate and analyze the intake of various nutrients, energy and food sources in protein. Comprehensive evaluation of individual and group dietary nutrition There are abundant sources of calcium in special nutrition diet or nutrition management software food: dried incense, sesame paste, shrimp skin, fresh bone products, broad beans, sea cucumber, wheat, bean flour and other good sources: egg powder, dried laver, celery, condensed milk, almonds, milk, ice cream, green leafy vegetables, caviar, laver, dried tofu and corncob.
