Eighty-two patients (mean age, 38 years) with irritable bowel
syndrome (IBS) were studied. Prior to June 2009, 39 patients were given
standard dietary advice (control group), which included regular meal
pattern; limiting insoluble fiber intake for diarrhea and increasing it
for constipation; reducing alcohol and caffeine intake; limiting fruit
to 3 portions a day; avoiding resistant starch (e.g., pulses, sweet
corn, green bananas); limiting sorbitol intake; and, in selected cases,
avoiding lactose, doing an elimination diet, and/or using probiotics.
From June 2009 onward, 43 patients were given a diet low in FODMAPs
(fermentable oligosaccharides, disaccharides, monosaccharides, and
polyols). This diet restricted foods high in fructans (e.g., wheat,
onion, garlic), galactooligosaccharides (e.g., chickpeas, lentils), and
sorbitol and other polyols; and, in patients with lactose or fructose
malabsorption, restricted foods high in lactose and fructose,
respectively. After an unspecified period of time, significantly more
patients in the low-FODMAPs group than in the control group reported
satisfaction with their symptom response (76% vs. 54%; p<0.04) and
improvements in bloating (82% vs. 49%; p=0.002), abdominal pain (85% vs.
61%; p=0.023), and flatulence (87% vs. 50%; p=0.001). Among 10 patients
who were asked, mean and median times to improvement were 3.5 and 2
weeks, respectively (range, 2-8 weeks).
Comment: Numerous studies have shown that food allergy and intolerance to specific food components (such as lactose, fructose, and sorbitol) can provoke gastrointestinal symptoms in people with IBS. The results of the present study indicate that other food components can also contribute to the symptomatology.
