Japan’s exceptional life expectancy is largely credited to its balanced and culturally respectful approach to food. This book examines how Japan’s nutrition practices promote public health and explores how key elements can be thoughtfully adapted to improve dietary habits in Iran—without copying, but by learning and integrating relevant, sustainable models.
Nutrition and public health
Healthy Food: The Secret of Japanese Health
Japan has one of the highest life expectancies in the world. That figure is not an accident of genetics — it rests on decades of mindful eating, careful individual choices, and health-focused public policy. Prof. Seyed-Moayed Alavian asks what is transferable from that model, and what is not.

About this book
Why Japan, and why nutrition? Japan's long average life expectancy reflects years of mindful living, intelligent individual and social choices, and health-focused policy. At the heart of that lifestyle sits a single decisive factor: what people eat.
While chronic disease, obesity, diabetes and metabolic disorders rise elsewhere, Japan has taken a different path — a diet that is balanced and simple yet diverse and nutrient-rich, supported by a culture that treats food not as calories or habit but as part of a healthy life.
From there the book's central question follows: why has nutrition in Japan been so effective, and which parts of it can realistically be adopted elsewhere? Iran has its own rich and varied food culture, but urbanisation, heavy consumption of processed food, and drift away from traditional habits have set off warning signs. This book responds not with imported formulas but with an adaptable model, drawn from a society that has demonstrated how food can shape a nation's future.
I do not seek to prescribe formulas or promote imported solutions. Rather, I aim to offer a practical and adaptable model for improving the health of society through nutrition.Prof. Seyed-Moayed Alavian — from the introduction
