How to distinguish staple food from non-staple food snacks

Staple food is the main source of human energy and nutrition, while non-staple food generally refers to informal meals and snacks.

Staple food refers to the traditional staple food on the table and the main source of energy needed. Because staple food is the main source of carbohydrate intake, especially starch, grains such as rice, wheat and corn with starch as the main component, and tuber foods such as potatoes and sweet potatoes are regarded as staple foods by people in different regions. Generally speaking, the staple food contains carbohydrates.

Non-staple food, that is, non-staple food, is generally processed food, including sugar, candy, canned food, tea, condiments, dairy products, honey products, bean products, beverages, biscuits, cakes, snacks, cigarettes, wine, fruits and so on. In the era of planned economy in China, staple food and non-staple food were strictly managed separately.
