We do not begin
on intuition alone.
The scale of the problem — and the fact that food interventions change outcomes — is already documented by research worldwide. Here is the evidence behind this project, with sources.
The numbers behind a neglected field.
What happens when the joy of eating is left outside medicine shows up clearly in the statistics.
The final decade is not a healthy one
In Japan, the gap between life expectancy and healthy life expectancy is 8.49 years for men and 11.63 for women — roughly a decade of life’s final chapter lived without health and independence. Japan’s aging rate of 29.3% is the world’s highest, headed for 34.8% by 2040.[1] [2] [3]
Malnutrition inside the hospital
A meta-analysis of 64 studies found malnutrition in 39% of inpatients (53% by direct GLIM diagnosis), roughly doubling mortality risk. In nutritionDay, the world’s largest hospital food survey, about half of medical inpatients showed weight loss or reduced food intake.[7] [8]
Thirty percent of what is cooked is left uneaten
Across 32 studies, hospital plate waste has a median of 30%, with 27% of served energy discarded. More than half of inpatients do not finish their meals — and patients eating only about a quarter of their food faced 2.1 times the 30-day mortality risk.[10] [11]
The limits of “safe but joyless” food
Texture-modified diets — minced, molded, thickened for safety — are associated with weight loss, malnutrition, and lower mealtime satisfaction. In Japan, 22.4% of women over 65 already trend toward undernutrition. Reconciling safety with joy is the next frontier.[14] [5]

Behind every number,
there is a table.
Food interventions change outcomes.
And research shows the other side of the ledger: improve the food, and the numbers move.
Restore the appearance, restore the appetite
In an RCT of dysphagia cuisine reshaped to look like real dishes, twelve weeks improved energy and nutrient intake, with an average weight gain of 3.9 kg. Looking delicious is nutrition.[15]
Food service improvement works
A systematic review of 36 studies found that multi-component hospital food service interventions — better menus, plating, and delivery — significantly improved intake, satisfaction, and quality of life.[16]
Pleasure of eating is nutrition
In a study of 464 older adults living at home, pleasure of eating was significantly associated with nutritional status. Joy is not a preference — it is an independent factor in nutritional risk.[13]
The world is already moving.
Lyon, France
Thierry Marx × public hospitals
Starred chef Thierry Marx opened the brasserie “La Villa” inside a Hospices Civils de Lyon hospital (2018) — a pioneering effort to raise the hospital food experience to first-class dining standards.[21]
Singapore
SGH × beloved food brands
Singapore General Hospital co-developed patient meals with famous names like JUMBO, reaching an 89% meal acceptance rate — overturning the assumption that hospital food must be bland.[22]
Herlev, Denmark
A chef's à la carte, in a hospital
Herlev Hospital introduced “Herlevs Herligheder” (2022): some 120 chef-made dishes ordered by tablet. Intake improved on wards with many malnourished patients, while food waste fell.[23]
We will measure as we go.
From its Phase 1 hospital meals onward, Maison de Santé will track these indicators — building evidence from Japan, one plate at a time.
Meal completion
Plate waste, measured — the most honest metric of deliciousness.
Nutritional status
Standard measures such as GLIM and MNA to verify the nutritional effect of co-designed meals.
Mealtime experience
The joy of eating, recorded quantitatively and qualitatively.
Recovery & clinical indicators
Length of stay and recovery, followed together with clinical teams.

Evidence begins
with a single plate.
Common questions.
What is Clinical Gastronomy?
A methodology in which clinicians share the clinically required parameters (nutrition, swallowing function, disease) and then chefs and clinicians co-design safety, nutrition, and deliciousness as a single dish. Not medicine supervising cuisine — equal expertise working together.
How is this different from “medically correct meals”?
Beyond meeting nutritional standards, we design the joy of eating — aroma, texture, appearance, finish — at the same time. Research links pleasure of eating to nutritional status in older adults, and shaped dysphagia cuisine has been shown to improve intake and body weight.
Is there evidence behind this project?
Worldwide, multi-component hospital food service improvements have improved intake, satisfaction, and quality of life, and medically tailored meals have reduced hospitalizations by 49% and lowered healthcare costs in peer-reviewed studies. Maison de Santé will build its own evidence from Japanese hospital food, measuring intake, nutritional status, and satisfaction.
How can hospitals, companies, and chefs take part?
Hospitals and facilities can start with an adoption inquiry; companies join through sponsorship, co-development, or adoption partnerships; chefs enter the selection for the Chef Council. Use the join pages or the contact form.
