Soy sauce and its functionality

Abstract

　Food is the source of life. Practicing a healthy diet on a daily basis and eating delicious and enjoyable food gives people the joy of living and greatly contributes to a healthy and prosperous life. Extending healthy life expectancy has become an important issue in Japan, and one of the factors contributing to this extension is dietary habits. Seasonings are used to add flavor to foods and make them tasty according to individual tastes. Soy sauce, an indispensable seasoning in Japanese cuisine, has not only a "sensory function" that provides enjoyment and satisfaction in terms of taste, aroma, and deliciousness, but also a "biological regulatory function" related to disease prevention, health recovery, physical condition management, and aging control.

　Today, many people are concerned about their eating habits due to high blood pressure, kidney disease, allergies, and so on. If soy sauce, which is consumed daily, can contribute to providing foods suitable for such people, it is believed that it will help extend their healthy lifespan and improve their quality of life, and several soy sauce products have been developed.
