Some ways to promote healthy eating are planting a vegetable garden, take a trip to a farm or farmer's market, when teaching kids turn healthy eating into a fun experience, encourage people to keep food logs, eat healthy around others, show videos or give presentations about healthy eating, talk or remind people about the benefits of healthy eating, start or attend cooking classes, offer healthy alternatives, show ways to eat fruits and vegetables in different ways (apples with peanut butter or carrots with ranch), etc.
I think that the most important thing is the continuous experience and the attempt to develop and the trend to explore more herbs and try to include them in medical drugs
