Problems solved by technology

[0006] Aiming at the problem that the current dietary energy evaluation standard is single and the evaluation results of different body types are not highly targeted, the present invention proposes a dietary energy calculation method combined with individual BMI, and proposes a corresponding method for different individuals’ different energy intake requirements. The calculation standard of dietary energy uses the calculation method of energy nutrition curve to quantify the individual dietary energy into specific scores, and then the assessment and grading of individual dietary energy can be realized according to the obtained energy scores

Abstract

The invention relates to a BMI (body mass index) combined individual dietary energy calculation method and belongs to the field of nutriology from the aspect of application scenarios and belongs to the fields of computer science and health information from the aspect of technology implementation. The BMI combined individual dietary energy calculation method includes: firstly, calculating daily energy intake and daily energy consumption of individuals, wherein the daily energy intake is divided by the daily energy consumption to acquire dietary energy consumption ratio of the individuals; secondly, calculating the BMI of the individuals, and adopting different dietary energy calculation standards for individuals with different BMI ranges; finally, substituting the dietary energy consumption ratio of the individuals to a dietary energy calculation formula structured according to energy nutrient curves to acquire final dietary energy points of the individuals. The corresponding dietary energy calculation standards are put forwards according to acceptable daily intake of different individuals, the energy points acquired can be used for evaluating reasonableness of the dietary energy of the individuals, and more accurate and individualized effect in the aspect of dietary energy evaluation of the individuals is achieved.

Description

technical field [0001] The invention relates to a method for calculating individual dietary energy combined with body mass index (BMI). From the perspective of application scenarios, it belongs to the field of nutrition; from the perspective of technical realization, it also belongs to the field of computer science and health informatics. Background technique [0002] With the rapid development of the economy and the significant improvement of the quality of life, the dietary structure and lifestyle of Chinese residents have undergone tremendous changes. The main nutritional problems faced by the Chinese population have changed from single malnutrition to nutritional imbalance and overnutrition. According to the "Report on Nutrition and Chronic Disease Status of Chinese Residents" released in 2015, the physical development and nutritional status of Chinese residents have generally improved, and the adult malnutrition rate is 6.0%, which is 2.5 percentage points lower than th...
