Closed-valley meal, a concept of catering, originated from "dietotherapy" in China's traditional health-preserving recipes. Closed grain is a food made of ground grain powder, vegetables, beans and other ingredients mixed with water or soup. The invention has the characteristics of comprehensive nutrition, easy digestion and enhanced immunity, and is suitable for people with weak body and dyspepsia. It is one of the best choices for healthy diet.

The closed-grain meal is different from other health-care meals, and its uniqueness lies in the closed-grain meal used. This traditional staple food, which was originally considered as a rural folk, has been rediscovered in the trend of healthy eating. Closed valley contains high dietary fiber, vitamins, minerals and other nutrients, which can protect the stomach and promote body absorption. Especially for the gastrointestinal problems of most modern people, the closed-grain meal gives a good solution.

A closed-grain meal is characterized by the use of powdered ingredients. Different from traditional meals, closed-grain meals often mix various powders with various vegetables and side dishes, enriching the taste and enhancing the nutrition. Consumers who like early adopters can try the exotic food brought by the closed-valley meal and enjoy the fun of eating different from the traditional meal. However, diet also needs to be combined with personal physique, health status and life needs to make choices, so when eating closed-grain meals, we should pay attention to balanced collocation and rich nutrition.
