许多证据证明膳食对非酒精性脂肪肝的发展有明显的作用,而膳食中果糖对非酒精性脂肪肝的作用还存在争议。膳食中果糖的来源多样,包括蔗糖分解产生的果糖,天然食品及饮料中的高果糖浆。本文回顾了关于果糖与非酒精性脂肪肝关系的流行病学研究论文。尽管不能对果糖单独引起非酒精性脂肪肝或者使这种疾病恶化下结论,但患者应该减少果糖摄入,尤其是减少富含高果糖浆软饮料的摄入。软饮料不像水果一样有高营养价值,减少软饮料摄入量在降低果糖摄入总量中尤为关键。而水果中的果糖相对安全,不需要刻意减少水果的食用量。对脂肪肝患者进行膳食指导时,注重的不仅仅是膳食成分的数量,而且应该注意膳食的质量。
There is much evidence that diet has a significant effect on the development of non-alcoholic fatty liver and that the effect of dietary fructose on non-alcoholic fatty liver is still debatable. Dietary sources of fructose vary, including sucrose decomposition of fructose, natural foods and beverages high fructose syrup. This article reviews epidemiological research papers on the relationship between fructose and non-alcoholic fatty liver. Although it is not possible to conclude that fructose alone causes or worsens non-alcoholic fatty liver disease, patients should reduce their intake of fructose, especially reducing the intake of soft drink rich in high fructose syrup. Soft drinks do not have the same high nutritional value as fruits and reducing soft drink intake is particularly crucial in reducing total fructose intake. Fructose in fruit is relatively safe, do not need to deliberately reduce the amount of fruit consumption. Dietary guidance for patients with fatty liver, the focus is not only on the number of dietary ingredients, but should pay attention to the quality of the diet.
