小白鼠缺乏苏氨酸时常因消耗过多的热量去合成脂肪而发生脂肪肝。用缓和热量限制法可以预防这种脂肪肝的发生。实验结果表明当摄取热量下降30％时,肝脂肪的积儲就可减少到正常范围内。这说明了氨基酸和热量之间的平衡对于控制肝脂肪的积储是重要的。但此法不能预防因缺乏胆碱而造成的脂肪肝。这就说明了热量限制法有希望下降因过量摄取炭水化合物而促进的肝脂肪的积累,但难于影响因脂肪运输所造成的肝脂肪的积储。 Lack of threonine mouse often due to excessive consumption of calories to fat synthesis and fatty liver. With the calorie restriction method can prevent the occurrence of this fatty liver. Experimental results show that when the calorie intake decreased by 30%, liver fat accumulation can be reduced to the normal range. This shows that the balance between amino acids and calories is important for controlling the accumulation of hepatic fat. However, this method can not prevent fatty liver caused by lack of choline. This shows that the calorie restriction method has the potential to reduce the hepatic fat accumulation promoted by excessive intake of carbohydrates, but it is difficult to affect the accumulation of hepatic fat due to fat transport.
