Oishii Kenko Inc. (CEO: Tetsuya Nojiri), which operates the AI meal planning and nutrition management app 'Oishii Kenko' with the concept of 'AI for Families,' has announced the results of its 'Food Price Surge Survey,' which independently analyzed fluctuations in food prices and the prices of recipes supervised by its registered dietitians. This survey, which analyzed the 10 years from 2016 onwards, revealed the reality of rising food prices as well as the existence of foods with stable prices. The 'Food Expense Estimation AI' was also featured on NHK's 'Shuto-ken Joho Netadori!' broadcast on June 5, 2026.
■ Key Survey Findings
Food prices have generally increased compared to 2016. Cabbage, for example, recorded an index exceeding 300 (more than 3 times that of 2016), indicating particularly large price fluctuations for vegetables, seaweed, and legumes.
The average price index for recipes supervised by Oishii Kenko's registered dietitians has also risen. Main dishes and staples reached an index of 138, and side dishes reached 134 (January 2016 = 100).
Price increases vary by recipe. It was found that by choosing recipes with stable prices, it is possible to create meal plans that control food expenses even amidst rising prices.
■ Background of the Survey
Amidst continuing price increases, many users expressed concerns such as 'It's difficult to plan meals because ingredients are getting more expensive' and 'I'm trying to save money while considering nutrition, but I'm reaching my limit.' In response, the company conducted its own analysis of ingredient prices and found that recipe selection significantly impacts food expenses and that some ingredients maintain stable prices. Based on this knowledge, the 'Food Expense Estimation AI' feature, which displays estimated food expenses for recipes and meal plans, was released in January 2026.
■ Survey Overview
Survey Name: Food Price Surge Survey
Analysis Target (External Data): Ministry of Internal Affairs and Communications, Retail Price Survey (Trend Data) Tokyo Metropolitan Area (January 2016 - December 2025)
Analysis Target (Recipes): 1,264 Oishii Kenko registered dietitian-supervised recipes for which price calculations were possible throughout the entire period (January 2016 - December 2025).
Analysis Method: Smoothing using a 3-month moving average, time-series clustering (classified into 4 groups).
Analysis Conducted by: Oishii Kenko Inc. (Independent Analysis).
■ Main Survey Results
Overall Food Prices Have Risen
Analysis of food prices in Tokyo's wards revealed an upward trend across all categories compared to 2016. Vegetables, seaweed, and legumes showed particularly large price fluctuations, with cabbage recording a price index exceeding 300 (more than triple that of 2016) in early 2025. Conversely, chicken and eggs showed relatively stable price trends.
Oishii Kenko's Recipe Prices Have Also Increased
Price indices reflecting the price fluctuations of ingredients were calculated for 1,264 Oishii Kenko dietitian-supervised recipes. By 2025, the price index for main dishes and staples reached 138, and for side dishes, it reached 134 (January 2016 = 100), confirming an overall increase in the food cost burden for households.
Meal Planning for Expense Reduction: 'Savings x Nutrition' Proposals
Analysis of price fluctuation patterns classified recipes into four clusters: 'Expensive When Out of Season,' 'Continuous Price Increases,' 'Slow Price Increases,' and 'Affordable Keepers.' By actively proposing recipes from the 'Affordable Keepers' cluster with low price index increases, or recipes that become cheaper in season, the company aims to support households in maintaining nutritional balance while saving money. This insight became the starting point for the development of Oishii Kenko's 'Food Expense Estimation AI.'
