Characteristics and evaluation methods of Meiji NPS

Meiji NPS is a framework for evaluating the nutritional value of food based on the nutritional components,
and is aimed at helping resolve nutritional health issues.
The system was designed by considering the differences in dietary habits between Japan and other countries,
as well as the health issues faced by each life stage of the Japanese population.

Background and Design of the Meiji NPS

We published our new approach to nutrition as the “Meiji Nutrition Statement.” One of the goals of this statement is to help resolve existing nutritional health issues. To achieve this goal, we believe it is important to address and integrate into this system the nutritional health issues faced by individuals and consider the special dietary habits of each region. Based on this, we have designed the Meiji Nutrition Profiling System (Meiji NPS) as a unique tool to help address current nutrition issues.

A Nutrition Profiling System (NPS) is a framework for scientifically evaluating the nutritional value of food, and it is necessary to design the system keeping specific targets in mind. Therefore, based on the goals of the “Meiji Nutrition Statement,” the Meiji NPS is characterized primarily by its consideration of the differences between Japanese and western dietary habits. Furthermore, in order to address the health issues that affect people of various age groups in Japan, we have developed the Meiji NPS algorithm in consultation with numerous experts.

Meiji Nutrition Statement

Meiji NPS Overview

The Meiji NPS is an innovative framework that aims to help improve various nutritional health issues, with the aim of supporting people at all stages of life. We are taking on the challenge of designing an appropriate NPS for each stage of life, including younger children (3 to 5 years), older children (6 to 11 years), adults (12 to 64 years), and older adults (65 years and older). Accordingly, we have developed four models—the Meiji NPS for Younger Children, the Meiji NPS for Older Children, the Meiji NPS for Adults, and the Meiji NPS for Older Adults.*1~4 Each model has been designed with reference to official guidelines and data*5 published by public organizations and academic associations. In the future, we plan to expand our support by developing NPSs for the global markets where Meiji products are sold.

The Meiji NPS for Adults

The Meiji NPS for Adults is designed to address the two major nutritional health issues faced by Japanese adults: lifestyle-related diseases and the thinness of young women. The score is based on the amounts of specific nutritional components being defined, including nutritional components that should be limited (sugar, saturated fatty acids, salt, etc.) and components that should be recommended (protein, dietary fiber, etc.).

The Meiji NPS for Older Adults

The Meiji NPS for Older Adults is designed with special consideration given to frailty, a major health issue for the older adults in Japan. With specific emphasis given to preventing frailty, the nutritional recommendations are based on the Meiji NPS for Adults, eliminating the recommendation for limiting saturated fatty acids.

The Meiji NPS for Younger and Older Children

The Meiji NPS for Younger and Older Children is designed with special consideration given to growth and development, a major health issue for the younger and older children in Japan. It evaluates the same nutritional components as the Meiji NPS for Adults, but the reference values used in the calculations have been adjusted to meet the specific nutritional requirements of younger and older children.

Meiji NPS targeting different life stages
It uses an image to explain the target and health issues of the Meiji NPS. It addresses the different nutritional issues at each stage of life, such as "Growth and Development" for early and late childhood, "Lifestyle-Related Diseases" and "Thinness in Young Women" in adulthood, and "Frailty" in old age. It also explains that we do not intend to create an NPS for children less than three years old.

Our Goals

We have designed the Meiji NPS as a tool to measure the healthiness of food products, with the aim of helping to resolve nutritional health issues for Japanese people at different life stages, while also considering the differences between Japanese and western dietary habits. We will use the Meiji NPS to develop and improve our products to provide higher nutritional value. In the future, we will also strive to provide customers with valuable information such as the nutritional value of each product evaluated by the Meiji NPS and suggestions to help them choose healthier foods. We aim to benefit our customers and society through these initiatives to address nutritional health issues.

The Nutritional Profiling System allows us to provide customers with information on the nutritional value and consumption of foods, and is also useful for our product development and improvement. The image shows how we contribute to customers and society through solutions to nutritional issues.

Meiji NPS for Adults Evaluation Methods

About the Meiji NPS for Adults

The Meiji NPS for Adults is a framework for scientifically evaluating the nutritional value of foods, taking into consideration lifestyle-related diseases and the underweight problem faced by young Japanese women.*6 *7 The Meiji NPS evaluates foods based on serving size (the amount consumed at one time) and the amounts of several nutritional components. Specifically, the nutritional value is evaluated based on the amounts of recommended nutritional components (e.g. protein, dietary fiber), food groups (e.g. vegetables, dairy products), and nutritional components that should be limited (e.g. salt, sugar) per serving size.

The nutritional value of the food is indicated and visualized by a score on a scale of 0.5 to 5.0. Higher scores indicate a higher nutritional value for the food.

Evaluation by serving size

Meiji NPS is evaluated and scored based on the nutritional content per serving size (the amount consumed at one time). Evaluation based on serving size is closer to the actual amount consumed and is easy for consumers to use. The serving size in Meiji NPS is according to the reference value and ordinary serving value for Japanese people.

Generally, reference values are indicated on food packaging and are used to show consumers how much of a particular food or ingredient they should consume each day. On the other hand, the ordinary serving value refers to the standard amount of commonly consumed products. It is used in various situations, such as in nutritional management and practice. Taking these points into consideration, examples of serving sizes in the Meiji NPS are shown to the right.

Serving sizes for milk, chocolate, cheese, and ice cream are explained with an image. Serving sizes for milk, chocolate, cheese, and ice cream are explained with an image.

Nutritional components and food groups used for evaluation

The Meiji NPS for Adults is evaluated based on the following nutritional components and food groups contained in various foods. These are developed with reference to official guidelines and data published by public organizations and academic associations.

This is an image that explains the recommended nutritional components. There are five recommended nutritional components - protein, calcium, dietary fiber, iron, and vitamin D - that are commonly deficient and whose intake is recommended.

A higher score indicates a higher nutritional value for the food. Finally, the Meiji NPS scores are classified into 10 levels ranging from 0.5 to 5.0.

The score is based on the amount of nutritional components and food groups per serving size. The score is higher when the amount of recommended nutritional components and food groups are higher, and the amount of the limited nutritional components is lower. To make the nutritional value easier to understand, the score is finally calculated on a scale of 0.5 to 5.0 in 10 levels.

In addition, an epidemiological study has shown that a high score on the diet index evaluated using the Meiji NPS for Adults is associated with low values for various lifestyle-related disease indicators*8, which means that choosing products with high scores on the Meiji NPS for Adults corresponds to higher nutritional value.

Meiji NPS for Older Adults Evaluation Methods

About the Meiji NPS for Older Adults

The Meiji NPS for Older Adults is a scientific evaluation method for the nutritional value of foods, with special consideration given to frailty among the older generation in Japan.*9*10 It was designed based on Meiji NPS for Adults, but iron and saturated fatty acids were removed from the nutritional component list because of their lack of relationship with frailty based on previous evidence. On the other hand, vitamin D, which is considered important for the prevention of frailty, was given a higher value in Meiji NPS for Older Adults.

The NPS for Older Adults is based on serving size, and the results of this evaluation are shown a score on a scale of 0.5 to 5.0. Higher scores indicate a higher nutritional value for the food.

The scores are 3.5 for adults and 4.5 for older adults. There is a difference of 1.0 in the scores.

The differences in nutritional needs of adults and older adults are reflected in these scores.

Milk is rich in protein and calcium, which are recommended nutritional components in the Meiji NPS. With a score of 5.0 for both the Meiji NPS for Adults and for Older Adults, milk is can be expected to contribute to the prevention of both lifestyle-related diseases in adults and frailty among older adults.

Cheese is made from milk and contains protein, calcium and vitamin D, but also contains nutrients to limit such as salt and saturated fatty acids. As a result, the NPS score for adults was 3.5, and the NPS score for older adults was 4.5. The cheese production process involves removing water, and the nutrients contained in the milk are concentrated in the cheese. The results from Meiji NPS for Older Adults was higher than the results from Meiji NPS for Adults, because it is assumed to be a food suitable for older adults, who tend to eat less, as it is rich in nutrients that can be expected to contribute to the prevention of frailty, such as protein, calcium, and vitamin D.

The Meiji NPS for Adults was developed with the aim of preventing lifestyle-related diseases and thinness among young women, while the NPS for Older Adults was developed with the aim of preventing frailty among older adults. By evaluating foods using scales with different objectives according to life stages, some foods, such as milk, will have the same score for both NPSs, but others, such as for cheese, where the scores are different.

The nutritional value of foods is not uniform, and it is important to use appropriate evaluation methods that match the characteristics and health needs of the target population. The Meiji NPS will continue to contribute to the solution of various nutritional and health issues, closely aligned with a wide range of life stages.
