The invention discloses carnitine grafted polyvinyl alcohol cross-linked hydrogel and a preparation method and application thereof, and belongs to the technical field of food, health care products or medical instruments.The carnitine grafted polyvinyl alcohol cross-linked hydrogel is obtained by grafting L-carnitine with polyvinyl alcohol in an acid environment and then conducting cross-linking through polycarboxylic acid. The preparation process does not use organic solvents, and is simple, economical and convenient. The grafting rate of the L-carnitine grafted polyvinyl alcohol is 1%-30%, and the swelling multiple of the carnitine grafted polyvinyl alcohol cross-linked hydrogel is 50-150 times when the carnitine grafted polyvinyl alcohol cross-linked hydrogel reaches swelling equilibrium in an acidic aqueous solution with the pH value of 2. The carnitine grafted polyvinyl alcohol cross-linked hydrogel disclosed by the invention is large in water absorption expansion times under an acidic condition, increases the volume occupying the stomach to provide satiety and reduces food intake, is limited in water absorption times or degraded and collapsed under a neutral / alkaline condition, is beneficial to being discharged out of a body, can be used for preparing weight-losing products, assists in controlling diet, and has a good market prospect. The effects of preventing or assisting in treating obesity and diseases caused by obesity and the like are achieved.

The present invention provides a dietary food, in particular a meal replacement in the form of bars, for weight-controlling diets, said dietary food comprising 6 wt.% or less than 6 wt.% digestible and energy-providing carbohydrates, a high content of non-metabolizable carbohydrates, and a protein content from 25 wt.% to 50 wt.%. The invention further provides a method for preparing such dietary food and its use in treating diseases connected with pathological overweight.

The utility model discloses a quantitative diet dinner plate, and relates to the technical field of diabetes nursing. The dinner plate comprises a dinner plate body, the front face and the back face of the dinner plate body are both fixedly connected with lead screw shells, the two lead screw shells are arranged in a mirror image mode with the dinner plate body as the center, and the sides, close to each other, of the two lead screw shells are both fixedly connected with the outer surface of the dinner plate body. The dinner plate partition plates are arranged, specifically, the round knob is rotated anticlockwise, the two-way lead screw fixedly connected is made to rotate, and the dinner plate partition plates located on the left side and the right side are made to move in the direction close to each other through threaded connection of the two-way lead screw and the dinner plate partition plates. In this way, the dinner plate partition plates can be moved through the two-way lead screws, the distance between the two dinner plate partition plates and the distance between the dinner plate partition plates and the inner surface of the dinner plate body are adjusted, a user can conveniently control the partition capacity of the dinner plate body, and a patient can conveniently control diet.

The invention discloses a portable quantitative oil control lunch box which comprises a dish containing box body, four first spaces are formed in the upper surface of the dish containing box body, matching spaces capable of forming sealing are formed in the upper ends of the first spaces, clamping spaces are formed in the lower sides of the matching spaces, and oil storage boxes are just placed in the clamping spaces. A dish box placed in the matching space is placed in the oil storage box, a plurality of oil seepage grooves are formed in the bottom of the dish box, and the lunch box and the matching notch part are arranged in a matched mode, so that the lunch box can be reversely buckled on the dish containing box body after eating is completed, the overall occupied size is reduced, and convenience is improved; meanwhile, the lunch box, the lunch box cover and the sealing cover are connected more stably and are convenient to carry due to the arrangement of a clamping groove part, a convex part and a convex rib part; meanwhile, the liftable oil storage box can adjust the residual oil content of the dishes, the oil content can be adjusted in real time according to actual eating experience, and oil-controlled diet is achieved.
