Referring to fig. 1, a flowchart of a nutrition balanced diet recommendation method based on user physical health data according to a first embodiment of the present invention is shown, and the method includes the following steps:
Acquiring health basic information and requirements of a user, wherein the health basic information comprises allergy sources, contraindications and personal preferences, and the requirements comprise weight losing, fat reducing, shaping, body building and three-high reducing;
Establishing a user personalized dietary nutrient demand database according to health basic information and demands of users, wherein the personalized dietary nutrient demands comprise daily dietary nutrient intake demands and meal dietary nutrient intake demands;
Establishing a food material nutrient database and a dish nutrient database, wherein the food material nutrients comprise a plurality of heat, protein, fat, carbohydrate, sodium, calcium, iron, potassium, zinc and the like;
establishing a dish feature tag database, wherein the dish feature tag comprises: meat and vegetables, vegetable series, taste, crowd, spicy degree, dish nutrition function, allergen and the like;
Acquiring dish information of the dining hall at the current day, and calculating the range of the dishes suitable for the user to eat at the current time according to the dish information, wherein the dish information comprises dish data such as main side dish collocation details, flavoring details and the like;
According to dietary nutrients required by the user at the time of meals, balanced nutrition collocation is carried out from dishes suitable for the user at the time of meals, the rationality of collocation results is checked, and reasonable collocation results are recommended to the user.
Wherein, the health basic information of the user also comprises gender, age, height, weight, physical activity level, exercise state and the like. The calculation formula of the daily meal caloric requirement of the user is as follows:
daily dietary caloric requirement NeQ-E (kcal) =basal metabolic rate BMR physical activity level factor;
Basal metabolic rate BMR (kcal) = (9.99 x body weight W (kg) +6.25x height H (cm) -4.92x age ag+sex adjustment factor s);
Wherein, the range of alpha is 1.2-1.9, and the sex adjustment factor s: such as: female value-161 and male value 5.
The daily dietary nutrient intake demand calculation formula is:
Carbohydrate intake demand NeQ-Car (g) = (daily meal caloric demand e×carbohydrate energy supply ratio Cc)/4;
Fat intake demand NeQ-Fat (g) = (daily meal caloric demand E Fat energy duty ratio Fb)/9;
protein intake demand NeQ-Pr (g) = (daily dietary caloric demand E (100% -carbohydrate energy duty cycle Cc-fat energy duty cycle Fb))/4;
Wherein, cc range: 50% -65%, fb scope: 20% -30%.
The nutrient intake requirement per meal was calculated:
nutrient demand three meal distribution coefficient θ: breakfast = 30%, lunch = 40%, dinner = 30%;
meal caloric requirement per meal MeNeQ-E (kcal) =daily meal caloric requirement E (kcal) ×three meal distribution coefficient θ;
carbohydrate intake demand per meal MeNeQ-Car (g) = (calorie demand per meal NeQ-E carbohydrate energy duty cycle Cc)/4;
fat intake demand per meal MeNeQ-Fat (g) = (calorie demand per meal NeQ-E Fat energy duty cycle Fb)/9;
Protein intake demand per meal MeNeQ-Pr (g) = (caloric demand per meal NeQ-E (100% -carbohydrate energy duty Cc-fat energy duty Fb))/4;
Wherein, cc range: 50% -65%, fb scope: 20% -30%.
The related formula is calculated by the dish nutrient content (/ 100 g):
Wherein, the vegetable nutrient content (/ 100 g) is calculated: kappa is the edible rate of the food, gamma is the nutrient retention rate in cooking, delta is the finished product vegetable yield, M (g) is the use weight of a certain food in the dishes, n is the number of the food types, n is a positive integer, 1,2, … …, n, M (g) is the total weight of the dishes, foC-Pr (g/100 g) is the protein content in a certain food, foC-Fat (g/100 g) is the Fat content in a certain food, and FoC-Carb (g/100 g) is the carbohydrate content in a certain food.
The specific method for calculating the range of the dishes suitable for the user when the user eats the dishes according to the dish information comprises the following steps: according to the information of the canteen dishes, the dishes are divided into at least two stages, wherein the primary classification comprises meat dishes, vegetable dishes, staple food and fruits, the secondary classification of the meat dishes is divided into meat dishes and meat dishes, the secondary classification of the staple food is divided into staple food pastries and coarse food grains, and the vegetable dishes and the fruits are not subjected to the secondary classification, namely the secondary classification of the vegetable dishes and the fruits is the same as the primary classification. And the user is prevented from being allergic, contraindicated and disliked, and the remaining dishes are suitable for eating the dishes when the user meals the day.
According to dietary nutrients required by a user when the user eats dishes, the following conditions are simultaneously satisfied when the user eats dishes properly and the rationality of the matching result is checked: the structure of the meal dishes needs two-stage classification full coverage; maximizing the number m of edible vegetable varieties, wherein m is a positive integer; the actual intake of meal dish weight Q (g) needs to be minimized; the actual target rate Targ (%) of nutrient intake needs to fall within the limit range, i.e., the amount of nutrient intake should be distributed to the dining hall in x dishes (meat dishes, half meat dishes), vegetables, staple food (containing minor cereals) and fruits) at the time of dining, and the expected actual intake/intake of calories, proteins, fats and carbohydrates are within the allowable range of difference. Wherein, the target achievement rate Targ-E (%) of caloric actual intake is controlled in the range of 90% -110%; actual protein uptake target achievement rate Targ-Pr (%) control range [90% -120%); actual Fat intake target achievement rate Targ-Fat (%) control range [75% -110%); the actual carbohydrate uptake target achievement rate Targ-Carb (%) was controlled in the range of 75% -110%. As shown in table 1.
