Light food is a kind of catering which evolved from the theoretical basis of scientific diet.

The word "light food" is directly interpreted in terms of its meaning, which refers to food with a small amount. In a broad sense, snacks such as porridge, steamed stuffed bun, jiaozi, spring rolls, steamed dumplings, fruits, cakes and biscuits can all be regarded as a kind of light food, so "tea drinking" by Cantonese in China and "afternoon tea" by Europeans can be enjoyed during non-dinner hours.

So, another meaning of eating lightly refers to simple food that you can eat without spending too much time. Having a full stomach, stopping hunger and not much weight can be said to be the original concept of "light food", and sandwiches are the best representative. In recent years, because of the healthy wind, lettuce salad is the first menu to be included in the healthy light diet. In fact, "light food" does not refer to a specific food, but a form of catering. Light refers not only to the weight of ingredients, but also to the simple cooking method of ingredients, which preserves the original nutrition and taste of ingredients.

The development of light food in China:

The introduction of the concept of light food in China mainly comes from the convenience store culture that has gradually emerged in cities in recent years. Convenience stores with Japanese ancestry usually sell typical light food such as rice balls, sandwiches, sushi, cold noodles, salads, and Guandong cooking, and urban white-collar workers who are busy with their work and pay attention to healthy eating have become the first people to accept and love light food.

among many convenience stores, only FamilyMart, a family, promotes light food as a concept. Many of its light food products are clearly marked with calorie values on the packaging for customers to choose, and at the same time, a series of light food products that meet the dietary needs of Chinese people are introduced by combining the light food culture from Japan with the eating habits of Chinese people. Therefore, China's light food doctrine is closely related to convenience store culture, which also reflects the rapid development of domestic cities and the attitude of urbanites.
