6. The method for performing nutritional calculation based on different dining stages according to claim 4, characterized in that: The step of judging whether all the consumed dishes meet a preset possibility condition for occurrence of a phenomenon of nutritional value change based on the number of consumed dishes includes: Determining whether the number of consumed dishes is greater than or equal to a preset threshold value of the number of consumed dishes; When it is determined that the number of consumed dishes is greater than or equal to the threshold number of consumed dishes, determining that all consumed dishes meet a preset possibility condition for occurrence of a phenomenon of nutritional value change; When it is determined that the number of ingested dishes is less than the ingested dishes number threshold, it is determined that all the ingested dishes do not meet the preset possibility condition for the occurrence of the nutritional value change phenomenon.

7. The method for calculating nutrition based on different dining stages according to claim 5, characterized in that: The determining, based on the type and weight of each of the ingested dishes, whether there is an ingested dish among all the ingested dishes that meets a preset dose-effect change condition includes: According to the type of each of the ingested dishes, determining whether there is a target ingested dish among all the ingested dishes that meets a preset condition of a dish property that can be changed by a dose-effect; When it is determined that the target ingested dish exists among all the ingested dishes, determining whether the ingested dish weight of the target ingested dish is greater than or equal to a preset ingested dish weight threshold; When it is determined that the weight of the target ingested dish is greater than or equal to the ingested dish weight threshold, determining that there is an ingested dish that meets a preset dose-effect change condition among all the ingested dishes; When it is determined that the weight of the target ingested dish is less than the ingested dish weight threshold, it is determined that no ingested dish among all the ingested dishes satisfies the preset dose-effect change condition.
