I think it's a good idea, in Indonesia itself it's still integrated with other subjects such as biology but it doesn't stand alone. Even though it is very good and the impact on future life and sustainability.

This is a very important question Schools dieting is not universally adopted unfortunately. We can see in some countries that nutrition of the students starts in the primary schools and teachers may give lessons to the students about healthy diet in some countries. This policy is not adopted there neither in the primary or secondary schools in many low income countries. I agree that we should stress on policymakers to start educational lessons on healthy diet starting from the primary school through the university and not only secondary schools. Of course an additional budget would be required for this but this budget can be minimized through the following suggestions

1-The lessons on healthy diet can be added actually to the same curriculum of the of the biology for example .This issues would make it easier for the policymakers from the financial point of view .

2-Also the teachers or the schools and the management can allocate few minutes once or twice per week during the flag elevation ceremony to talk about healthy diet .

3-Pamphlets on healthy diet can be printed out and distributed to the students .

4-Posters can be mounted on the walls in the schools for the same purpose .

5-Pop-ups talking on healthy diet can be added to the Wi-Fi programs

6- TV programs also can be usefull in this aspect .

7-These suggestions are applicable to other unhealthy habits such smoking and alcoholism .

These suggestions are applicable as well in all sectors and departments of the society ,such as governmental institutes , clubs , privet sectors ---etc .When such endeavors are undertaken by all members and bodies of the society ,then we shall expect a better health for all .

The absence of healthy nutrition courses in secondary education is a major oversight, given that lifelong eating habits shape health outcomes; integrating nutrition into curricula could reduce obesity, eating disorders, and chronic diseases, fostering a culture of food literacy and well-being.
