    摘要:

    随着社会经济水平的快速提高,我国居民膳食结构发生了明显的改变。膳食脂质是膳食结构的重要组成部分,其推荐摄入量对改善居民膳食结构,实现新时期健康中国建设目标的都有着重要影响。对中国居民膳食脂质参考摄入量的修订提出几点建议。(1)我国18岁及以上居民的膳食脂肪供能比可接受范围上限(U-AMDR)是30%E,低于欧盟和北美国家的35%E。有学者建议提高我国成年人膳食脂肪供能比的U-AMDR,但仍缺乏足够的证据,暂不宜做修改。然而,考虑到老年人需要高能量和营养密度膳食的特点,应考虑提高老年人膳食脂肪的U-AMDR。(2)一些研究表明n-6/n-3多不饱和脂肪酸比值(n-6/n-3PUFA)与多种慢性非传染性疾病发生风险密切相关。我国居民膳食中n-6/n-3PUFA比值的平均值达到8.6,在某些人群中甚至更高。因此,建议将膳食中n-6/n-3PUFA比值的推荐值纳入新版膳食脂质参考摄入量推荐中。(3)尽管开展了大量研究,但膳食胆固醇摄入量与心血管疾病等多项慢性疾病发生结局之间的关系仍不明确。我国城市居民平均每日胆固醇摄入量为264.0 mg,农村居民为168.8 mg,处于正常范围。基于目前的研究证据,仍无法针对一般成年人群制订膳食胆固醇摄入限量。对于心脑血管疾病等慢性疾病的患者,建议参考相应疾病指南中膳食胆固醇摄入量的推荐。

    Abstract:

    With the rapid development of economy and society, the dietary pattern of Chinese residents has undergone obvious transition. The recommendation of dietary lipids intake has a significant influence on the improvement of dietary pattern and on the achievement of Healthy China goals in the new period. We put forward some suggestions on the revision of dietary lipids reference intake for Chinese residents. (1) The upper limit of acceptable macronutrient distribution range (U-AMDR) of percent of energy (%E) from fat for residents aged 18 years and above in China is 30%E, lower than that in countries of European Union and North America, which is 35%E. Some scholars suggest raising the U-AMDR of dietary fat for Chinese adults, but there is still insufficient evidence for modification. However, considering the characteristics of high-energy and nutrient-dense diets required by the elderly, increasing the U-AMDR of dietary fat in the elderly should be considered. (2) Some studies have shown that the ratio of n-6/n-3 polyunsaturated fatty acids (n-6/n-3PUFA) is closely related to the risk of multiple chronic non-communicable diseases. The average dietary n-6/n-3 PUFA ratio of Chinese residents is 8.6, and even higher in some populations. Therefore, it is recommended that the recommended values of dietary n-6/n-3PUFA ratio be included in the new dietary lipid reference intake recommendations. (3) Despite numerous investigations, the relationship between dietary cholesterol intake and the outcomes of several chronic diseases, such as cardiovascular disease, remains unclear. The average daily cholesterol intake was in the normal range, 264.0 mg in urban residents while 168.8 mg in rural residents. Based on current research evidence, it is still inappropriate to set dietary cholesterol limits for the general adult population. For patients with chronic diseases such as cardiovascular and cerebrovascular diseases, it is suggested to refer to the recommendations on dietary cholesterol intake in the guidelines of control and prevention for corresponding diseases.
