TL;DR
This study explores how the price of Japanese restaurant menu items relates to their nutritional balance for young adults.
Contribution
The study introduces a nutritional balance score (NBS) and examines its relationship with price for young adults in Japanese restaurants.
Findings
Menu items assessed using men's nutritional criteria had higher average NBS than those using women's criteria.
The relationship between price and NBS in most restaurants followed a concave pattern, peaking at specific price points.
Top NBS menu items were mostly set menus or rice bowls offered by fast-food restaurants.
Abstract
Eating habits are a contributing factor to obesity. Higher-priced menu items have better nutritional quality/balance, as the relationship between the price of food per serving and nutritional quality/balance has been reported. However, previous studies on the nutritional content of restaurant menu items did not focus on the relationship between the nutritional balance of menu items and prices. Therefore, this study aimed to investigate this relationship. The nutritional balance score (NBS) was defined and calculated according to each nutritional criterion of men and women aged 18–29 years, covering more than 2,000 menu items in 26 Japanese restaurant chains. Furthermore, NBS distribution by gender and restaurant brand, and the relationship between the menu item’s NBS and price were assessed. The results showed that the average NBS of the analyzed menu items differed between the…
