| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental Group | Experimental | During the study period, all subjects were required to avoid a diet high in zinc in order to avoid interference with dietary zinc intake and reduce bias in the weeks 1-2. In the weeks 3-4, all subjects were started to receive zinc supplementation at the normal adult dose (zinc tablets: 1 tablet (10mg Zinc) once daily after meals), while maintaining the avoidance of high-zinc foods. |
