Secondary school students need three reductions + three health, to develop and adhere to healthy habits and behaviors, and to effectively prevent and control chronic diseases. The three reductions include: salt reduction, oil reduction, sugar reduction, and the three health includes: healthy mouth, healthy weight, healthy bones.
