Description

Technical Field

[0001] The present invention relates to the technical field of medical care monitoring, and in particular to a nutrition intake analysis method based on diet monitoring. Background Art

[0002] With the advancement of technology, the use of artificial intelligence and computers to monitor and manage personal dietary nutritional intake has also made great progress. Commonly used technologies include:

[0003] Using AI-driven diet management applications can simplify daily nutrition tracking. This method can quickly record food intake and calculate personalized energy and nutritional needs based on the user's biological data. Healthy weight management and overall health goals can be achieved by connecting to large food databases and AI analysis.

[0004] Leveraging Computer Vision Technology: Food Image Recognition: Computer vision technology can identify food and estimate its nutritional content such as calories, macronutrients, and micronutrients.

[0005] The above technologies can help users better understand and manage their eating habits and provide personalized nutritional advice and meal plans by combining artificial intelligence, computer vision and big data analysis.

[0006] Chinese patent authorization announcement number CN104867081B provides an intelligent health management terminal, server, system and method, and its system includes: a food analyzer, a health management server and a health management terminal; the health management terminal receives the food weight information weighed by the food analyzer, and sends the food information and user information to the health management server. The health management server calculates the food nutrition data based on the food information and user information, and sends the food nutrition data to the health management terminal. The terminal, server, intelligent health management system and method of the invention can perform more accurate food intake detection by automatically calculating and displaying the nutritional information of food, and prompt the user when the nutrient intake is about to reach or has exceeded the warning value, and give reasonable dietary guidance suggestions, reasonably plan the dietary intake, and maintain a healthy diet, which can make dietary monitoring more humane and more easily achieve the goal of health management of the human body.

[0007] It can be seen that the above-mentioned method of monitoring dietary intake only simply records the user's energy intake, but lacks reasonable and reliable guiding value for the user's long-term regulation. Summary of the invention

[0008] To this end, the present invention provides a nutritional intake analysis method based on dietary monitoring to overcome the problem in the prior art that the monitoring method cannot be changed according to the physical condition of the monitored target, thereby resulting in non-objective monitoring of the nutritional intake and metabolic level of the monitored target.

[0009] To achieve the above object, the present invention provides a method for analyzing nutrient intake based on dietary monitoring, comprising:

[0010] Set a set of monitoring targets and collect dietary data for each monitoring target according to the basic period;

[0011] Determine the energy consumption and energy intake of each monitoring target during the basic cycle, and determine the corresponding energy retention rate;

[0012] Dividing the monitoring target set into a plurality of sub-target sets according to the energy retention rate of each monitoring target;

[0013] Set several periodic gradients in each sub-goal set and set corresponding monitoring periods respectively;

[0014] Monitor the corresponding monitoring targets respectively according to the monitoring cycle, and divide each monitoring target into a corresponding sub-target set according to the end time of each monitoring cycle;

[0015] During the analysis period, the corresponding paths of each monitoring target divided into each sub-target set are collected and recorded as the metabolic level change paths of the corresponding monitoring target.

[0016] Furthermore, the method for collecting the dietary data includes:

[0017] Determining the meal interval length and meal frequency of the monitored target;

[0018] Determining the dietary type and corresponding cooking method of the monitored target in a single basic cycle;

[0019] Calling the diet database to determine the list of nutritional components provided by the diet category under the corresponding cooking method;

[0020] Recording a list of several nutritional components obtained by the monitoring target in a single basic cycle, and generating a nutritional intake group corresponding to the monitoring target;

[0021] The nutritional intake group includes a list of several nutritional components and corresponding intake amounts.

[0022] Further, the steps in determining the energy expenditure and energy intake of a single monitoring target include:

[0023] Reading the nutritional intake group of the monitoring target and determining the corresponding energy intake;

[0024] Determining the energy expenditure of the monitored target in a single basal cycle and comparing it with the energy intake to form a comparison result;

[0025] Determine the corresponding calculated energy retention and actual energy retention according to the comparison result;

[0026] generating an energy retention rate of the monitored target;

[0027] The calculated energy reserve is related to the corresponding values ​​of the energy consumption and the energy intake, and the actual energy reserve is related to the weight change of the monitored target.

[0028] Further, when determining the energy intake of any monitoring target, a corresponding energy intake is generated according to the actual intake of the monitoring target in the basic period and the actual nutrient intake group;

[0029] Among them, the actual nutrition intake group uses the basic period as the sampling period.

[0030] Further, when determining the energy consumption of any monitoring target, the amount of movement of the monitoring target in the basic period is recorded as the actual energy consumption;

[0031] Wherein, when recording the energy consumption, if the monitored target consumes energy in the basic cycle, the energy consumption is recorded as a positive value, and if the monitored target stores energy in the basic cycle, the energy consumption is recorded as a negative value.

[0032] Furthermore, when recording the amount of exercise, a device capable of recording potential energy changes is worn at a preset position of the corresponding monitoring target, and the accumulated potential energy of the device during the basic period according to the monitoring target is recorded as the energy consumption.

[0033] Further, when determining the energy retention rate of a single basal cycle, the energy retention rate of the single basal cycle is determined according to the energy intake and energy expenditure of the next basal cycle.

[0034] Further, when determining the energy retention rate of any monitoring target, the monitoring target is divided into a sub-target set corresponding to the energy retention rate, and a new energy retention rate of the monitoring target is determined according to the gradient period corresponding to the sub-target set;

[0035] For the monitoring target, when a new energy retention rate is obtained, the target is divided into a new sub-target set.

[0036] Furthermore, the sub-goal sets are set according to the energy retention rate gradient, and a monitoring period is set for each sub-goal set.

[0037] The monitoring period is proportional to the energy retention rate of the sub-goal set.

[0038] Furthermore, a single analysis cycle includes no less than 2 basic cycles and no less than 3 monitoring cycles.

[0039] Compared with the prior art, the beneficial effect of the present invention lies in that, by dividing the metabolic level of the monitored target to form a sub-target set, the corresponding monitoring period is set gradiently, and the monitored target is adjusted to the corresponding sub-target set according to the actual metabolic level of the monitored target, so as to adjust the corresponding monitoring period according to its corresponding metabolic level. While effectively improving the monitoring accuracy of the monitored target, by confirming the adjustment process of the monitored target in each sub-target set, the change of the metabolic level of the monitored target with the monitoring time is determined, which effectively avoids the errors in diet monitoring caused by diet or monitoring cycle, thereby effectively improving the adaptability of diet monitoring.

[0040] Furthermore, by introducing the impact of cooking methods on the production of raw materials, the changes in nutritional intake of the corresponding monitoring targets are determined, and the corresponding list of nutritional components is periodically determined. While avoiding the changes in nutritional components caused by cooking methods, changes in energy intake caused by cooking methods for the same type of raw materials are prevented, thereby effectively reducing the dietary monitoring errors caused by cooking, thereby further improving the adaptability of dietary monitoring.

[0041] Furthermore, the corresponding energy retention is determined based on the weight of the monitored target and the energy consumption caused by its exercise, and the metabolic level of the monitored target is characterized based on the energy retention. While effectively eliminating the diet monitoring errors caused by individual differences, the stability of monitoring is improved, thereby further improving the adaptability of diet monitoring.

[0042] Furthermore, by monitoring the metabolic changes of the target over a longer period and adjusting the monitoring period of the target according to the metabolic changes, the stability of dietary monitoring is improved while effectively avoiding monitoring abnormalities caused by too short a monitoring period, thereby further improving the adaptability of dietary monitoring.

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0048] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] See also Figure 1 As shown, it is a flow chart of the nutritional intake analysis method based on dietary monitoring of the present invention, and the nutritional intake analysis method based on dietary monitoring includes:

[0050] Step S1, setting a monitoring target set, and collecting dietary data of each monitoring target according to a basic period;

[0051] Step S2, determining the energy consumption and energy intake of each monitoring target in the basic cycle, and determining the corresponding energy retention rate;

[0052] Step S3, dividing the monitoring target set into a plurality of sub-target sets according to the energy retention rate of each monitoring target;

[0053] Step S4, setting a number of periodic gradients in each sub-goal set, and setting corresponding monitoring periods respectively;

[0054] Step S5, monitoring the corresponding monitoring targets respectively according to the monitoring cycle, and dividing each monitoring target into a corresponding sub-target set according to the end time of each monitoring cycle;

[0055] Step S6, collecting the corresponding paths of each monitoring target divided into each sub-target set within the analysis period and recording them as the metabolic level change paths of the corresponding monitoring target.

[0056] Generally, the basic cycle can be set to 3 days, the monitoring cycle can be set to 1-5 days, and the analysis cycle can be set to 42 days.

[0057] By dividing the metabolic level of the monitored target to form sub-target sets, the corresponding monitoring period is set gradiently, and the monitored target is adjusted to the corresponding sub-target set according to the actual metabolic level of the monitored target, so as to adjust the corresponding monitoring period according to its corresponding metabolic level. While effectively improving the monitoring accuracy of the monitored target, the adjustment process of the monitored target in each sub-target set is utilized to determine the change of the metabolic level of the monitored target with the monitoring time, which effectively avoids the errors in diet monitoring caused by diet or monitoring cycle, thereby effectively improving the adaptability of diet monitoring.

[0058] See also Figure 2 As shown, it is a flow chart of collecting dietary data of the present invention, and the method of collecting dietary data includes:

[0059] Step S101, determining the meal interval and meal frequency of the monitored target;

[0060] Step S102, determining the diet type and corresponding cooking method of the monitored target in a single basic cycle;

[0061] Step S103, calling a diet database to determine a list of nutritional components provided by a diet category under a corresponding cooking method;

[0062] Step S104, recording a list of several nutritional components obtained by the monitoring target in a single basic cycle, and generating a nutritional intake group corresponding to the monitoring target;

[0063] Among them, the nutritional intake group includes a list of several nutritional components and the corresponding intake amounts.

[0064] In practice, cooking can in some cases lead to:

[0065] A. Heat changes, such as:

[0066] Frying: During the frying process, food absorbs a lot of oil, which significantly increases the calories. 100 grams of potatoes originally have about 77 kcal, but after frying, the calories may rise to more than 500 kcal.

[0067] Boiling: Boiling does not introduce additional fat and the calorie change is smaller, but some nutrients may dissolve in the water and be lost.

[0068] B. Vitamin loss: Vitamin C and B vitamins are sensitive to high temperatures. Long-term high-temperature cooking such as boiling, steaming, and baking will lead to significant loss of these vitamins. For example, the vitamin C in spinach can lose more than 30% after boiling for 3 minutes. Microwave heating time is short, which can reduce the loss of vitamins. Compared with traditional cooking methods, it can better retain the vitamins in food.

[0069] C. Mineral retention: Minerals are more stable than vitamins, but some minerals such as potassium and sodium are easily dissolved in water when boiled or blanched. Soup should also be used appropriately to reduce the loss of minerals. Dry heat methods such as roasting and frying can better retain minerals, but it is necessary to control the temperature and time to prevent overheating.

[0070] D. Antioxidants: Lycopene in tomatoes is released more during the heating process, thus increasing its antioxidant capacity. Therefore, proper heating can help the absorption of certain antioxidants. Antioxidants such as lutein may be destroyed at high temperatures, so low-temperature rapid processing is recommended.

[0071] E. Protein denaturation: Protein denatures at high temperatures, making it easier to digest and absorb. For example, the absorption rate of eggs is about 50% when eaten raw, but it can reach more than 90% after being cooked.

[0072] It is understandable that the nutrients contained in the same ingredients will change accordingly after being cooked in different ways.

[0073] By introducing the impact of cooking methods on raw materials, the changes in nutritional intake of the corresponding monitoring targets are determined, and the corresponding list of nutritional components is periodically determined. While avoiding the changes in nutritional components caused by cooking methods, changes in energy intake caused by cooking methods for the same type of raw materials are prevented, thereby effectively reducing the dietary monitoring errors caused by cooking, thereby further improving the adaptability of dietary monitoring.

[0074] Specifically, the steps in determining energy expenditure and energy intake for a single monitoring target include:

[0075] Read the nutritional intake group of the monitoring target and determine the corresponding energy intake;

[0076] Determine the energy expenditure of the monitoring target in a single basic cycle and compare it with the energy intake to form a control result;

[0077] Determine the corresponding calculated energy retention and actual energy retention according to the comparison result;

[0078] Generate the energy retention rate of the monitored target;

[0079] Among them, the calculated energy retention is related to the corresponding values ​​of energy consumption and energy intake, and the actual energy retention is related to the weight change of the monitored target.

[0080] Specifically, when determining the energy intake of any monitoring target, a corresponding energy intake is generated based on the actual intake of the monitoring target during the basal period and the actual nutrient intake group;

[0081] Among them, the actual nutrition intake group used the basal period as the sampling period.

[0082] Specifically, when determining the energy expenditure of any monitored target, the amount of movement of the monitored target during the basic cycle is recorded as the actual energy expenditure;

[0083] When recording energy consumption, if the monitored target consumes energy in the basic cycle, the energy consumption is recorded as a positive value; if the monitored target stores energy in the basic cycle, the energy consumption is recorded as a negative value.

[0084] The corresponding energy retention is determined based on the weight of the monitored target and the energy consumption caused by their exercise, and the metabolic level of the monitored target is characterized by the energy retention. While effectively eliminating the diet monitoring errors caused by individual differences, the stability of monitoring is improved, thereby further improving the adaptability of diet monitoring.

[0085] Specifically, when recording the amount of exercise, a device capable of recording potential energy changes is worn at a preset position of the corresponding monitoring target, and the accumulated potential energy of the device during the basic cycle of the monitoring target is recorded as energy consumption.

[0086] In implementation, the accumulation of potential energy can be measured by a watch or pendant worn on the wrist of the monitored target;

[0087] In particular, when calculating the energy consumption of the monitored target, the weight corresponding to the monitored target and the potential energy accumulated by the device are weighted. For example:

[0088] The watch worn by monitoring target A, who weighs 75kg, accumulated potential energy of about 2000 steps during the monitoring period; the watch worn by monitoring target B, who weighs 60kg, accumulated potential energy of about 2000 steps during the monitoring period;

[0089] At this time, when calculating the consumption of monitoring target A and monitoring target B in the monitoring period, the corresponding consumption is determined according to their corresponding weights;

[0090] Obviously, the consumption generated by monitoring target A is greater than that generated by monitoring target B.

[0091] The watch worn by the monitoring target A, who weighs 75 kg, accumulated potential energy of about 2000 steps in the first monitoring cycle; the watch worn by the monitoring target A, who weighs 75 kg, accumulated potential energy of about 3000 steps in the second monitoring cycle;

[0092] At this time, when calculating the monitoring target A in the first monitoring cycle and the second monitoring cycle, the corresponding consumption in the second cycle is greater than that in the first cycle.

[0093] It should be understood that the above description is only for convenience. In practice, when using a watch, mobile phone or pendant to record the monitored target, the number of steps or any unit that can only express quantity should not be used as the recording standard, but the corresponding potential energy should be recorded:

[0094] Taking a fully automatic mechanical watch as an example, its accumulated potential energy should be accumulated through the impulse it receives. For example, the spring of a fully automatic mechanical watch cannot accumulate potential energy when it is not swinging.

[0095] Specifically, when determining the energy retention rate of a single basal cycle, the energy retention rate of the single basal cycle is determined according to the energy intake and energy expenditure of the next basal cycle.

[0096] Specifically, when determining the energy retention rate of any monitoring target, the monitoring target is divided into a sub-target set corresponding to the energy retention rate, and a new energy retention rate of the monitoring target is determined according to the gradient period corresponding to the sub-target set;

[0097] For the monitoring target, when obtaining a new energy retention rate, the target is divided into a new sub-target set.

[0098] In practice, the energy retention rate should not exceed 80% and should not be less than 40%;

[0099] When setting the gradient, you can design it with a gradient of 10%, and the corresponding monitoring cycles are:

[0100] Gradient 1: 40% to 50% corresponds to a monitoring period of 2 days;

[0101] Gradient 2: 50% to 60% corresponds to a monitoring period of 3 days;

[0102] Gradient 3: 60% to 70% corresponds to a monitoring period of 4 days;

[0103] Gradient 4: 70% to 80% corresponds to a monitoring period of 5 days;

[0104] During the entire analysis period of 42 days, a single monitoring target has a probability of moving in any way in the above gradient. If it does not reach the monitoring period, the gradient where it finally stays is recorded as the final gradient in the analysis period;

[0105] Specifically, the sub-goal set is set according to the energy retention rate gradient, and a monitoring period is set for each.

[0106] Among them, the monitoring period is proportional to the energy retention rate of the sub-goal set.

[0107] Specifically, a single analysis cycle includes no less than 2 basic cycles and no less than 3 monitoring cycles.

[0108] By monitoring the metabolic changes of the target over a longer period and adjusting the monitoring period of the target according to the metabolic changes, we can effectively avoid monitoring abnormalities caused by too short a monitoring period while improving the stability of dietary monitoring, thereby further improving the adaptability of dietary monitoring.
