[Part 1] Food Is About Making People Better: The Role of Dashi and the Basics of Taste

Introduction: Food Is About Making People Better

In Japanese, the character for “food” can be interpreted as meaning “to make people better.”
This is not just a play on words, but a philosophy deeply rooted in Japanese food culture.

We eat to survive, but food is more than nutrition alone.
On busy days, stressful days, or days when we feel low, we instinctively choose what to eat. Those choices, repeated day after day, shape both our physical condition and our state of mind.

The gateway to those decisions is our sense of taste.

What Is Taste? A Sensor for What the Body Needs

Taste is not only about preference.
It also functions as a biological sensor that helps the body identify necessary nutrients and avoid potential danger.

Humans perceive five basic tastes:

• Sweetness: Closely linked to our instinct to seek energy (sugars)
• Saltiness: Essential for maintaining mineral and fluid balance
• Umami: Signals the presence of amino acids and proteins
• Bitterness: Often serves as a warning sign for certain plant compounds or minerals
• Sourness: A刺激 from organic acids, related to metabolism and freshness

In other words, the five tastes are not merely about liking or disliking food.
They are information the body uses to stay alive.

Why Umami Matters: The Foundation That Balances All Tastes

Among the five tastes, Japanese cuisine has placed special importance on umami.

Unlike sweetness, umami does not strongly assert itself.
Unlike bitterness or sourness, it does not provide sharp stimulation.
Yet umami plays a central role because it has the power to define the structure of flavor and balance the entire dish.

When umami forms the foundation of a dish:

• Satisfaction increases without adding more salt
• Flavors come together without relying on excess sugar or oil
• Ingredients stand out, and the dish feels lighter

The Role of Dashi: Not Adding Flavor, but Bringing It Together

Dashi does not dominate a dish.
Instead, it quietly supports and enhances the natural qualities of the ingredients.

For example, miso soup made with good dashi feels complete even with less salt.
Simmered dishes prepared with dashi require less sugar or fat to achieve balance.

This is because dashi is not meant to “add” flavor,
but to bring balance to the five tastes and draw out the inherent potential of the ingredients.

The reason dashi became deeply embedded in Japanese food culture is not convenience alone.
It reflects a long-held belief that food should truly contribute to making people better.

Conclusion: Understanding Taste Is the First Step to Better Eating

• Taste is not only preference, but a system for receiving essential information
• Among the five tastes, umami serves as the foundation that brings balance
• Dashi does not add flavor—it organizes and supports the entire dish

Why are kombu and bonito such a powerful combination? The answer lies in their components.
