This is mainly because people usually don't pay much attention to their drinking health, so food and nutritional health are closely related to our daily life, which is a subject that we must recognize and attach importance to. Nutrition has a great influence on human health and must be paid attention to in the catering industry. The selection of catering raw materials and the formation of dish flavor provide scientific basis, and also provide practical methods for the protection of food nutrients in the cooking process. At the same time, it also provides theoretical and scientific guidance for popularizing scientific diet and balancing diet. In hotel management, paying attention to nutrition can provide reasonable nutrition for catering products, guide Chinese and foreign guests to eat scientifically, master the basic theoretical knowledge of nutrition, and strengthen the nutrition allocation of catering products, so that the catering products provided by chefs can retain the traditional flavor and have reasonable nutrition.
