Pioneering the Future of
Nutrition Health
and through
Data Science
Oishi Kenko contributes to the prevention and treatment of diseases
for the world’s 8 billion people by providing personalized nutrition and lifestyle solutions.
About
Oishi Kenko
At Oishi Kenko, we are dedicated to creating an environment where evidence-based dietary practices for disease prevention and treatment can be naturally and enjoyably incorporated into everyday home life.
For medical institutions and health insurance societies, our goal is to make high-quality dietary therapy accessible across all facilities.
Today, only about 10% of medical institutions in Japan have registered dietitians on staff, meaning that opportunities for patients and the general public to receive professional nutritional support remain significantly limited.
Our vision is to eliminate the burdens of lifestyle changes for disease prevention and treatment—empowering people to embrace both the joy of eating and long-term health.
