Abstract:
Objective To investigate the nutrient contents of various grains in Hubei Province, and to provide a scientific basis for a balanced diet. Methods Various grains (except potatoes and beans) on the market in Hubei Province were collected. The samples were prepared by peeling and milling, or directly milling, and the nutrient contents were determined according to the national standard methods. With reference to the American nutrient profiling model, protein, dietary fiber, vitamin C, vitamin A, vitamin E, potassium, magnesium, iron and calcium, the nine nutrients were selected as recommended nutrients, and sodium, added sugars and fat were restricted nutrients. On the basis of 100 g for calculation, a nutrient-rich food model (Nutrient-rich foods, NRF9.3) was established and applied to evaluate the grains. Results The evaluation results showed that wheat and buckwheat grains contained a higher recommended nutrient content than restricted nutrient content, and had higher nutritional value. Among them, quinoa (black) had the highest NRF index of 102.4, indicating the most nutritional value. After peeling, the loss rate of nutrient value (NRF9.3 index) of various grains was 38.73% to 65.00%. Conclusion It is recommended that people should try to choose whole grains when purchasing grain products.
