In 1928, Professor Wu Xian, a biochemist, began purposefully and systematically analyzing and compiling research data on the nutritional value of foods. He published "Nutrition Value of Chinese Food," marking the first historically significant "Food Composition Table" in China. As fundamental information describing the nutritional characteristics of foods, nutrient composition data constitutes essential public health data for a nation. It serves as a key indicator of a country's nutritional science advancement and represents a strategic national resource, playing a vital role in guiding agricultural production, directing food processing, and balancing international trade.

  CnOpenData presents the China Food Nutrient Composition Database, featuring comprehensive and detailed nutritional information for over 1,700 foods. The dataset is organized into Nutrient Content Information Tables and Nutrient Score Information Tables, encompassing fundamental nutrients, lipids, minerals, vitamins, amino acids, and other nutritional components. This database establishes a foundation for investigating the nutritional status of China's population and provides robust data support for related research.
