The purpose of food promotion is to let more people understand and enjoy the charm of food, thereby promoting the prosperity and development of the local economy. Food is not only a taste enjoyment, but also a cultural and historical inheritance. In the process of food tourism, we can appreciate the cultural characteristics of different regions, and at the same time experience the simplicity and enthusiasm of the local people. Therefore, food promotion can not only promote local food, but also bring people from different regions closer together.

Food promotion can also drive the development of related industries, allowing local agricultural products, breeding, fishery and other industries to be newly developed and utilized. The unique taste and delicious quality of some famous delicacies are inseparable from the influence of regional climate, soil and farming methods. Therefore, while promoting food, it can also promote the development of local agriculture and fisheries, thereby promoting the development of the local economy.

Food promotion can not only bring economic benefits, but also promote people's physical and mental health. Food is not only a taste enjoyment, but also a way of healthy living. By promoting healthy food with fresh ingredients and pollution-free raw materials, more people can care about their dietary health and gradually form healthy eating habits. At the same time, food tourism can also relax people's body and mind, relieve the pressure of work and life, improve the quality of life, and promote physical and mental health.
