ABSTRACT

Background A rational diet is the foundation of health. Dietary guidelines for Chinese residents and Chinese Food Guild Pagoda aim to provide healthy eating guidance for Chinese residents. Objective To evaluate the rationality and applicability of the "Chinese Food Guild Pagoda" (2022). Methods The energy and nutrient supplies of foods recommended by the Food Pagoda-were calculated based on the chinese food composition Table. The degree of requirement satisfaction for energy or nutrients was calculated by comparing with the recommended nutrient intake (RNI) or adequate intake (AI) for adults (≥ 18 years) with light physical activity according to the Chinese dietary reference intakes. Results The estimated energy intake was 46662.79-10062.28 kJ, which met the 6697.36-10046.04 kJ set by the Food Pagoda. We estimated that 65.74-102.78 g of protein, 59.67-82.71 g of fat, and 211.27-333.19 g of carbohydrate were provided by following the Food Pagoda. Adequate vitamins and minerals were also provided by following the Food Pagoda. However, the amounts of vitamin E was estimated to be 2.40-3.28 times and sodium was 1.59-1.75 times of AI, while selenium was 63.40%-98.15% of RNI. Conclusion The amounts of vitamin E and sodium by following the Food Pagoda may be higher and selenium may be lower than recommended intakes. Energy and other nutrients in the Food Pagoda are suitable for general adults in China.
