Fast self-evaluation method and system for individual dietary nutrient intake levels

Abstract

The invention provides a fast self-evaluation method for individual dietary nutrient intake levels. The fast self-evaluation method comprises the following steps: collecting individual basic information of people to be evaluated, and searching evaluation standards meeting individual conditions; collecting the food intake frequency information of the people to be evaluated, and calculating the nutrient intake quantity of the people to be evaluated according to nutrient content data in food; evaluating the individual dietary nutrient intake levels according to the data, and guiding individual rational diet. The invention further provides a fast self-evaluation system for the individual dietary nutrient intake levels. The fast self-evaluation system comprises basic information collecting module, a food frequency information collecting module, a food nutrient content data base module, an evaluation standard module, a calculation module, a data statistics module and a system management module. Based on the conventional technology, a fast self-evaluation software platform for Chinese resident dietary nutrient intake levels is established and is popularized in the society, so as to help people in different areas and of different physiological states and different disease states to evaluate the individual dietary nutrient intake levels every day by selves, guide the people to select proper diet schemes and nutrient supplement schemes, and provide an information tool for realizing national rational diet and promoting healthy.

Description

technical field [0001] The invention belongs to the field of human nutrition information evaluation and guidance, and in particular relates to a method and system for rapid self-evaluation of individual dietary nutrient intake levels. Background technique [0002] Nutrients are chemical components that can provide energy to the human body, form the body and tissue repair, and have physiological regulation functions. All kinds of substances that can maintain human health and provide growth, development and labor are called nutrients. The intake of nutrients by the human body Insufficiency or excess can easily cause disease. [0003] Taking iodine as an example, iodine is an essential trace element for the human body and an important raw material for the thyroid gland to synthesize thyroid hormones. Iodine deficiency exists to varying degrees in most countries, and worldwide, especially for preschool children and pregnant women in low-income countries, iodine deficiency remai...

Problems solved by technology

[0009] In the same way, for the human body, the evaluation of other nutrients required must also be carried out by testing multiple indicators at the same time. The workload is heavy, and a high professional level is required. It is difficult to promote in the general population, so it is also necessary to explore a new method. A stable, reliable, simple and easy-to-use individualized evaluation method for human nutrients, so as to be promoted to the general population, facilitate the self-evaluation of the nutritional status of the masses, and help residents choose appropriate nutritional supplement methods scientifically and rationally
