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

  CnOpenData has launched the Chinese Food Nutrient Composition Data, encompassing comprehensive and detailed nutrient information for over 1,700 types of foods. The dataset is divided into Nutrient Content Information Tables and Nutrient Score Information Tables, covering nutritional aspects such as basic nutrients, lipids, minerals, vitamins, and amino acids. This initiative lays the groundwork for investigating the nutritional status of China's population and provides robust data support for related research.
