What this calculator looks at

What does this Okinawa Diet Calculator measure?

It scores selected habits associated with a traditional Okinawa-style pattern: plant-forward meals, sweet potatoes or root vegetables, colorful vegetables, soy foods, sea vegetables, legumes, modest animal foods, and mindful portions. It is not a longevity prediction tool.

Okinawa-style score components

The score favors meals built around root vegetables, vegetables, soy foods, seaweed, legumes, simple home cooking, and lower processed foods. It also includes a practical 80% fullness habit because many Okinawa-style descriptions discuss eating with restraint rather than eating until stuffed.

How to use the result

Use the result as a reflection tool. If your score is low, choose one habit to improve first, such as adding vegetables, replacing a processed snack with a simple meal, or using tofu/beans more often. Do not treat the number as medical advice.
