Irritable Bowel Syndrome (IBS) is a functional bowel disorder characterised by episodes of abdominal pain associated with altered bowel habits. Many IBS sufferers believe that diet may play a role in triggering these episodes and may avoid certain foods. However relatively few studies have undertaken a dietary assessment in IBS sufferers to examine the wider impact of the condition upon diet.
104 individuals with IBS were recruited and asked to complete a validated food frequency questionnaire (FFQ). The data were analysed against Dietary Reference Values for food energy and nutrients for the United Kingdom and observed intakes for the general population and for differences between IBS subtypes and the UK population.
The data show that the dietary intakes of this population of IBS sufferers met the UK Dietary Reference Values. The average energy intake of the population exceeded the Estimated Average Requirements of the UK population and the balance of macronutrients was favourable. Intakes of selected micronutrients significantly exceeded the reference nutrient intakes. There were no differences between IBS subtypes.
The IBS subpopulation appear to have an adequate and balanced macronutrient intake with no evidence of inadequate micronutrient intake.
肠易激综合征（IBS）是一种功能性肠病，其特征是腹痛发作伴有排便习惯改变。许多 IBS 患者认为饮食可能在引发这些发作中起作用，并可能避免某些食物。然而，很少有研究在 IBS 患者中进行饮食评估，以检查该疾病对饮食的更广泛影响。
招募了 104 名 IBS 患者，并要求他们完成一份经过验证的食物频率问卷（FFQ）。根据英国食品能量和营养素的膳食参考值以及一般人群的观察摄入量以及 IBS 亚型与英国人群之间的差异对数据进行了分析。
数据显示，该人群的 IBS 患者的饮食摄入量符合英国膳食参考值。该人群的平均能量摄入量超过了英国人口的估计平均需求量，宏量营养素的平衡情况良好。选定微量营养素的摄入量明显超过了参考营养素摄入量。IBS 亚型之间没有差异。
IBS 亚群的宏量营养素摄入量似乎充足且均衡，没有证据表明微量营养素摄入不足。
