What is edible education?

"Dietary education" is to nurture the ability to practice healthy eating habits by acquiring knowledge about "food" and the ability to choose a well-balanced "food" through various experiences. Since eating is a basic activity that lasts throughout the lifetime, "food education" is important as well as children, even after becoming an adult. In addition to thinking about how to eat healthily, we cook dinner and cooking with someone, experience the harvest of food, taste seasonal and regional cuisine, etc, through food education "a ring of practice Let's spread out ").
 "Eating ability" to be worn by food education includes "to be able to maintain mental and physical health" through meals, "to understand the importance and pleasure of meals", "choose foods yourself, eat "Enjoying the enjoyment of eating with family and friends", "Knowing the process of food production and having a feeling of appreciation" and so on. These are learned and educated in various places such as home, school, region, etc. from childhood. And, even after becoming an adult, I practice it for the rest of my life and keep growing up. In addition, adults also have the role of "communicating such knowledge and experience of food and Japanese food culture to the next generation".Quoted from Government Public Relations Online
