Abstract

The invention discloses a diet matching method and system based on multi-attribute decision making, which aim to provide a set of diet schemes meeting the diet standard for users by considering individual differences of the users. The method comprises the following steps of calculating the nutrient element content of each scheme, according to the personal information, formulating a dietary standard by the system, and finely adjusting the dietary standard, calculating cosine similarity between the dietary schemes and dietary standards, and generating candidate dietary schemes, enabling the userto autonomously replace dishes in the candidate dietary schemes, screening dietary schemes according to an energy ratio, and selecting one scheme by a user, recombining the dishes in the scheme to form a plurality of dietary schemes, and constructing a decision making matrix, and adopting an interval TOPSIS (approximate ideal solution sorting method) method to obtain an optimal dietary scheme. Aset of dietary scheme meeting the dietary standard and considering the individual difference of the user can be formulated for the user, the nutritional requirements and health requirements of the user are met, and a guarantee is provided for the disease prevention and treatment of the user.

Description

technical field [0001] The present invention relates to the field of nutrition and health, in particular to a method and system for meal matching based on multi-attribute decision-making. Background technique [0002] A reasonable diet is the basis for ensuring good health. In recent years, the nutrition and health status of Chinese residents has been significantly improved, but there are still problems such as undernutrition, overnutrition, and frequent occurrence of nutrition-related diseases, and unhealthy diets are still common among the population. [0003] The current nutritional status in my country is mainly manifested in: 1) malnutrition is still serious; 2) the problem of trace elements needs to be solved urgently; 3) the prevalence of chronic non-communicable diseases is increasing and the intensity of risk factors is increasing; 4) dietary structure, physical activity and The risks of obesity, hypertension, diabetes and dyslipidemia are closely related.
