    All participants attended to a two-part nutrition education program. The education intervention program was administered in two sessions, one week apart. Before the intervention, a pre-test was administered to determine the knowledge and beliefs attitudes of participants. After the pre-test each session consisted of a PowerPoint presentation of about 20 minutes. Education topics included components of adequate-balanced nutrition and its relationship with COVID-19, introduction of food groups, the association between COVID-19 and dietary supplements, herbal foods in the prevention/treatment of COVID-19, considerations regarding DS/HF, food-drug interactions, and COVID-19 drugs and food interactions. The presentation was concluded with the nutritional recommendations for COVID-19. The post-tests were shared with the participants at the end of the second session of the education intervention.
