-
摘要:
背景 合理膳食是保证健康的基础，我国制定了《中国居民膳食指南》及“中国居民平衡膳食宝塔”来指导居民合理膳食。
目的 评价“中国居民平衡膳食宝塔”（2022）的合理性和适用性。
方法 根据《中国食物成分表》提供的食物营养成分数据，计算膳食宝塔建议的各类食物提供的能量和营养素。以《中国居民膳食营养素参考摄入量》中18岁~年龄段轻体力成人的推荐摄入量（RNI）或适宜摄入量（AI）为标准，计算其能量和营养素的满足程度。
结果 各类食物提供的能量为6662.79~10062.28 kJ，符合膳食宝塔设定的6697.36~10046.04 kJ能量需要量水平。膳食宝塔提供了65.74~102.78 g蛋白质、59.67~82.71 g脂肪和211.27~333.19 g碳水化合物。膳食宝塔提供了较为合适的维生素和丰富的矿物质，但是维生素E是其AI的2.40~3.28倍，钠是其AI的1.59~1.75倍，硒只满足了其RNI的63.40%~98.15%。
结论 膳食宝塔所提供的维生素E和钠偏高，硒则偏低，能量和其他营养素适用于我国一般成人。
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 theChinese 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.
