Abstract
Description
Technical Field
[0001] The present invention relates to the field of intelligent health technology, and in particular to a method for generating dynamic adaptive dietary advice based on real-time biomarker monitoring. Background Art
[0002] In the prior art, personalized health consultation and dietary advice services are usually based on users' static health records and generalized nutritional guidelines. These services often ignore multi-dimensional information such as real-time changes in individual biomarkers, a person's specific lifestyle, psychological conditions, and a person's long-term health plan, resulting in a lack of accuracy and personalization in dietary advice.
[0003] Traditional health consultation services mainly rely on historical medical records and standardized nutritional advice. This approach has the following obvious defects: Traditional methods cannot monitor and analyze changes in user biomarkers, such as blood sugar, cholesterol, and blood pressure, in real time. The real-time data of these biomarkers is crucial for accurately adjusting dietary advice because they directly reflect the user's immediate health status. At the same time, the failure to fully integrate multiple aspects of data such as users' biomarker data, historical health records, lifestyle, and mental health information has led to a one-sided understanding of the user's health status and failed to provide comprehensive personalized health advice. Moreover, traditional dietary advice often adopts a "one-size-fits-all" approach and fails to provide customized services based on the user's personal preferences, dietary restrictions, and living habits. The user's personal preferences and living habits are crucial for developing a sustainable diet plan. Finally, existing health consultation services usually do not include an adaptive feedback loop to adjust subsequent advice based on the user's actual response to previous dietary advice. This static service model limits the real-time and adaptability of dietary advice.
[0004] Therefore, how to provide a method for generating dynamic adaptive dietary recommendations based on real-time biomarker monitoring is an urgent problem that needs to be solved by technicians in this field. Summary of the invention

[0166] Embodiment 1:
[0167] In Example 1, it is shown how a 35-year-old office worker Xiao Wang can improve his health through the personalized diet suggestion system of the present invention. In a recent physical examination, Xiao Wang's initial physical examination showed that his fasting blood sugar level was 7.9mmol / L, his total cholesterol level was 6.5mmol / L, and his blood pressure was 133 / 85mmHg, reflecting mild hypertension. His intestinal flora composition and metabolite levels showed no abnormalities. In his daily work, Xiao Wang often worked overtime, had irregular diet, and lacked sufficient physical exercise. Xiao Wang hopes to improve his health by adjusting his eating habits, but he does not know where to start.
[0168] After learning about the experience of accepting the personalized diet suggestion system of the present invention, Xiao Wang is first provided with a wearable device for monitoring his biomarkers around the clock. The system first analyzes his health status based on Xiao Wang's initial biomarker data using a machine learning algorithm, and generates the first version of personalized diet suggestions based on his living habits and dietary preferences. The suggestions include daily calorie intake, recommended food types, and dietary frequency, as shown in Table 1 below:
[0169] Table 1 Xiao Wang's four-week personalized dietary advice health improvement record
[0170]
[0171] As can be seen from Table 1 above, in the first week: the system recommended that Xiao Wang consume 2000 kcal of calories per day, mainly from whole grains, lean meat, vegetables and low-fat dairy products. It was recommended that he eat at least 500 grams of vegetables and fruits every day and limit the intake of high-sugar and high-fat foods. After one week, Xiao Wang's blood sugar dropped from 7.9mmol / L to 6.8mmol / L, cholesterol dropped from 6.5mmol / L to 5.9mmol / L, and blood pressure remained at 132 / 83mmHg.
[0172] Week 2: The system recommended that Xiao Wang consume 1950 kcal of calories per day. In view of the decrease in blood sugar and cholesterol, the system continued to maintain a low-sugar and low-fat diet, and added foods rich in omega-3 such as deep-sea fish to further lower cholesterol, and increased the proportion of coarse grains to control blood sugar. At the end of the second week, Xiao Wang's blood sugar dropped to 6.2mmol / L, cholesterol dropped to 5.5mmol / L, and blood pressure dropped slightly to 128 / 83mmHg.
[0173] Week 3: The system recommended that Xiao Wang consume 1900 kcal of calories per day. According to Xiao Wang's feedback, he said he wanted to try more diverse foods, so beans and nuts were added to the recommendation while keeping the total calories unchanged. The system also added regular physical activity recommendations, such as brisk walking three times a week. By the weekend, Xiao Wang's blood sugar further dropped to 5.9mmol / L, cholesterol reached 5.2mmol / L, and blood pressure stabilized at 127 / 80mmHg.
[0174] Week 4: The system recommends that Xiao Wang consume 1,900 kcal of calories per day. Xiao Wang reports that his energy level has improved and his work efficiency has also improved. The system optimizes the suggestions based on this and introduces intermittent fasting to encourage Xiao Wang's metabolic level to improve. At the same time, in order to better adapt to Xiao Wang's new lifestyle, the system recommends that he try food diversification, including more types of vegetables, fruits and plant protein sources. At the end of the fourth week, Xiao Wang's blood sugar stabilized at a normal level of 5.6mmol / L, cholesterol dropped to an ideal level of 4.9mmol / L, and blood pressure also dropped to an ideal level of 125 / 78mmHg.
[0175] Over a one-month period, the system continuously monitored changes in Xiao Wang's biomarkers and adjusted dietary recommendations based on real-time data and Xiao Wang's feedback. In this way, Xiao Wang's blood sugar level remained within the normal range, his cholesterol level was effectively controlled, his metabolic level improved, and his intestinal flora composition and blood pressure remained at a healthy level without adverse changes. In addition, Xiao Wang reported that he felt more energetic and his sleep quality improved.
[0176] The personalized dietary advice system in Example 1 demonstrates its effectiveness in real-time monitoring of biomarkers, generation of personalized advice, and adaptive adjustment. Xiao Wang's case demonstrates the effectiveness of the system in improving the health of users, adapting to personal eating habits and lifestyles, and promoting long-term health management. By monitoring the dynamic changes of user biomarkers in real time, personalized dietary advice that immediately responds to the user's current health status can be provided, which not only improves the accuracy of the advice, but also ensures the timeliness and relevance of the advice.
[0177] The present invention utilizes multimodal data integration and association analysis to comprehensively consider the user's biomarker data, historical health records, lifestyle, and mental health information, revealing the deep-level correlation of the user's health status, and providing strong support for formulating comprehensive personalized dietary recommendations.
