It has been suggested that the falling incidence and virulence of duodenal ulcer is related to increased dietary polyunsaturated essential fatty acid intake. The adipose fatty acid profile, which closely reflects dietary intake, was measured in 35 men with chronic duodenal ulcer and 35 matched control men. The mean percentage of linoleic acid in adipose tissue was significantly lower in the ulcer group (10.0 (0.7) v 12.3 (0.7)%, p less than 0.01) and this difference was found in both smokers and non-smokers. This finding suggests that the diets of duodenal ulcer patients are deficient in linoleic acid and this could be of aetiological importance.
有人提出,十二指肠溃疡发病率和毒力的下降与膳食中多不饱和必需脂肪酸摄入量的增加有关。对35名患有慢性十二指肠溃疡的男性和35名匹配的对照男性测量了能密切反映膳食摄入情况的脂肪脂肪酸谱。溃疡组脂肪组织中亚油酸的平均百分比显著较低(10.0(0.7)%对12.3(0.7)%,p<0.01),且在吸烟者和非吸烟者中均发现了这种差异。这一发现表明,十二指肠溃疡患者的饮食中缺乏亚油酸,这可能具有病因学意义。
