Description

Technical Field

[0001] The present invention relates to a health data information technology, in particular to an intelligent nutrition assessment and nutrition exercise intervention system based on nutrition and exercise principles. Background Art

[0002] According to the "Report on the Nutrition and Chronic Disease Status of Chinese Residents (2020)", first, the obesity rate of children under 6 years old in my country is 3.6%, the obesity rate of children and adolescents aged 6 to 17 is 7.9%, and the overweight and obesity rates of residents aged 18 and above are 34.3% and 16.4%, respectively. In recent years, the global overweight and obesity rates have been on the rise. Obesity is a chronic metabolic disease that not only leads to a higher risk of premature death, but is also closely related to the occurrence of various chronic non-communicable diseases, including type 2 diabetes, stroke, coronary heart disease, hypertension, respiratory diseases, osteoarthritis and gallstones, and is even related to the occurrence of various tumors. Second, the prevalence of hyperlipidemia in adults in my country is about 35.6%. Hyperlipidemia is a disease caused by the combined action of genetic and environmental factors that causes lipid synthesis and metabolic disorders, which can lead to serious complications such as stroke and coronary heart disease. At present, the effective prevention and control of hyperlipidemia not only helps prevent the occurrence and development of atherosclerosis, but also plays a key role in preventing cardiovascular and cerebrovascular diseases caused by it. Third, the muscle mass of normal adults will continue to decline with age. Among normal adults over 50 years old, muscle strength decreases by 12% to 14% every 10 years, accompanied by a progressive decline in muscle mass. 5% to 13% of the elderly between 60 and 70 years old suffer from sarcopenia. Among people over 80 years old, the prevalence of sarcopenia is as high as 11% to 50%. Fourth, osteoporosis is a bone disease with an increasing incidence with age. According to the results of the epidemiological survey released by the National Health Commission in October 2018, osteoporosis has become an important health problem for the middle-aged and elderly population in my country. The prevalence of osteoporosis in people over 50 years old is 19.2%, and the prevalence of osteoporosis in people over 65 years old is as high as 32.0%.

[0003] The common risk factors for overweight and obesity, hyperlipidemia, sarcopenia and osteoporosis are all closely related to unhealthy diet and insufficient physical activity. Lifestyle intervention, especially nutrition and exercise intervention, plays an important role in the prevention and treatment of the above-mentioned diseases. A healthy balanced diet and scientific and moderate exercise are the basis for preventing and controlling their occurrence and development and the guarantee for maintaining physical health.

[0004] Advantages and disadvantages of related technologies: 1. The Chinese invention patent application with the publication number CN110797108 A and the name of a targeted home dietary nutrition intervention method and management system is aimed at and refers to the national standards for patients with malignant tumors, hypertension, stroke, diabetes, hyperuricemia, gout and chronic kidney disease. The corresponding recipes are pre-prepared and stored in the database for users to choose, and then the correction guidance is made according to the actual dietary pattern of a certain user and the compliance with the pre-prepared recipes. In theory, this invention seems to have made the home dietary nutrition management suggestions for patients with diseases specific. However, if a family has N people, both healthy and sick, it is difficult to integrate different types of dietary patterns when dining together. In addition, this model cannot meet the needs of different regions, different eating habits and food diversification, let alone meet people's personalized nutritional needs that vary greatly. Because it is not a comparative analysis based on the calculation of all foods and all nutrients, the pre-set different target range values ​​are only relative to different target groups, and the dietary nutrition calculation analysis and nutritional intervention measures lack personalization and precise targeting.

[0005] 2. The Chinese invention patent application with publication number CN 117672465 A and name "A dietary nutrition intervention method, device, equipment and readable storage medium" uses the XGBoost model and the multi-objective raccoon algorithm to estimate the nutritional status of food and implement a nutritional intervention plan. The XGBoost model can be used as an auxiliary tool for calculating the content of food ingredients, and the food ingredient content is predicted by training the model. The multi-objective raccoon algorithm is usually used to solve multi-objective optimization problems in engineering design, financial forecasting and other fields. The calculation of food ingredient content usually relies on experimental data and nutritional ingredient data, rather than optimization algorithms. In short, the algorithm uses probability maximization to predict and measure dietary nutritional status and generate dietary nutrition intervention plans. It is not based on the calculation of the actual nutritional content of all foods. Therefore, the accuracy of the calculation result is obvious.

[0006] 3. The nutritional intervention measures formulated by relevant national departments and units for the "overweight and obesity, hyperlipidemia, sarcopenia and osteoporosis" groups basically recommend daily intake range values ​​for the five major food categories, namely, cereals and tubers, vegetables and fruits, animal foods, soy and nuts, and cooking oil and salt. At the same time, recommended range values ​​have also been formulated for the daily dietary intake levels of energy and fat, protein, carbohydrates, saturated fatty acid energy AMDR, dietary fiber, minerals and vitamins required by the above-mentioned disease groups. For the overweight and obese population, recipe examples for different eating habits in seven regions throughout the year have been designed. For the overweight and obese and hyperlipidemia population, the conversion amounts of 6 and 7 categories of food are listed respectively. Users can refer to the food exchange table and recipe examples, exchange and reasonably arrange three meals a day to meet their own healthy dietary needs.

[0007] However, there are still many problems in the implementation of the above-mentioned nutritional intervention measures, mainly: First, the results of measurement based solely on food range values ​​make it difficult for different individuals to accurately grasp their actual needs; second, it is impossible to know whether the dietary nutrient intake of each person is appropriate; third, each person has no way of knowing whether his or her energy intake level and composition ratio are reasonable; fourth, there are many types of food exchanges that are difficult to remember, and the execution of the operation is difficult, time-consuming and laborious.

[0008] In short, the existing technology cannot meet the high standard requirements of the overweight and obese, hyperlipidemia, sarcopenia and osteoporosis groups for accurate balance and appropriate dietary nutrition. There are still many problems and difficulties in the precise implementation of nutritional intervention, especially personalized intervention measures. CN110797108 A and CN 117672465 A are only dietary nutrition interventions and do not have exercise intervention functions. Summary of the invention

[0009] In view of the shortcomings that the existing technology cannot meet the high standards of accurate, balanced and appropriate dietary nutrition for groups with overweight and obesity, hyperlipidemia, sarcopenia and osteoporosis, and there are still many problems and difficulties in the accurate implementation of nutritional intervention, especially personalized intervention measures, the present invention provides an intelligent nutrition assessment and nutrition and exercise intervention system based on the principles of nutrition and exercise.

The dietary design of the two people is to choose the healthy elderly diet plan 1 and diet plan 3 of the "Dietary Guidelines for Chinese Residents" as their daily diet. The specific food and some nutritional content are shown in Table 6. The food classification and actual content of some nutrients in the 90-day diet are shown in Table 7 after the same and equal amount are replaced.

[0066] Table 6 shows the daily dietary foods and some of their nutritional contents:

[0067] 1. Calculate the total energy of all food consumed by the two people within 90 days, as well as the total energy of fat, saturated fatty acids, total water compounds, and protein, as well as the total content of protein, dietary fiber, calcium, phosphorus, sodium, magnesium, and vitamins A, C, and E.

[0074] Table 10 shows the calculation and evaluation results of daily exercise calorie burning value and weekly exercise duration for two people:

[0075] 5. Intervention Recommendations Intervention suggestion 1: Reasonable dietary structure.

[0076] The system judges that the dietary fiber, calcium and vitamin A of the two people, as well as the insufficient intake of animal food, whole grains, beans and potatoes, and the insufficient protein intake of the male, are not reasonable. The system recommends that the user take this seriously and adjust the dietary structure in time! Intervention recommendation 2: Specific food adjustment recommendations.

[0077] Please increase your daily intake of whole grains, beans and potatoes that are rich in dietary fiber. Specifically: first, increase the proportion of whole grains and beans in cereals to at least 25%, preferably 50%, and more than 100 grams per day, and reduce the amount of refined cereals such as rice and flour by the same amount; second, increase 100 grams of potatoes per day; third, convert all livestock meat into lean livestock meat or lean poultry meat.

[0078] Intervention suggestion 3: Recommend healthy recipes for independent selection. (The recommended recipes include those designed by our company based on different models and those recommended by relevant national authorities).

[0079] Intervention suggestion 4: Output relevant popular science knowledge. For example, the system outputs relevant knowledge about the physiological functions and effects of dietary fiber, vitamin A, calcium and protein, as well as insufficient intake of animal food, whole grains, beans and potatoes.

[0080] Intervention Recommendation 5: The insufficient exercise intensity and volume for the two people indicate that they cannot prevent sarcopenia and osteoporosis, which should be taken seriously.

[0081] Specific guidance and suggestions for exercise intervention: First, adjust the intensity of exercise appropriately. The simplest way to measure exercise intensity is the target heart rate method, which uses 170-age (years) as the target heart rate for moderate-intensity exercise. When the heart rate reaches this level, it means that the exercise intensity is just right; second, add sports that you can adapt to on the basis of existing projects, such as using dumbbells, elastic bands and other equipment for resistance training, and strive to train the muscles of the shoulders, chest, abdomen, back and limbs twice a week, 2-3 parts each time, and each muscle group is trained 2 days apart; third, increase the exercise time appropriately, and strive to reach more than 50 minutes a day. Fourth, provide independent selection of exercise training programs; fifth, output relevant scientific knowledge on exercise training.

[0082] During the verification process of the embodiments of the present invention, only the nutrients that are of key concern are calculated and verified. In fact, the calculation and evaluation of the dietary nutrition of the present invention covers all macronutrients, constant and trace elements, vitamins and other dietary components necessary for the human body. In view of the fact that the calculation and evaluation methods of these nutrients are basically the same, and because there are too many of them, it is too cumbersome to verify them one by one, so they are omitted.
