3. Microbiome composition associated with efficacy of low FODMAP diet in pediatric IBS
Low FODMAP diet reduced abdominal pain frequency in children with irritable bowel syndrome, and those who responded had different baseline gut microbial composition, according to study results.
"A low FODMAP diet appears to ameliorate GI symptoms in children with IBS,” the researchers wrote. “Those who responded robustly to the diet appear to have a different baseline microbiome composition, with greater saccharolytic capacity, than those who do not respond to a low FODMAP diet."

4. VIDEO: Expert discusses diet as emerging cause, management strategy for GI disease
William D. Chey
HONOLULU — In this exclusive video, William D. Chey, MD, FACG, professor of medicine at the University of Michigan health system, and director of the GI Nutrition and Behavioral Wellness Program at the University of Michigan, discussed the David Sun Lecture, which he delivered during the ACG 2015 Annual Postgraduate Course.
A “main message of my talk was the importance of having a GI dietician as part of a multidisciplinary team to manage patients with GI symptoms,” Chey said. “A GI dietician can not only make sure that any diet interventions are provided in a complete and medically responsible way, but they can also provide a a really important sounding board that can actually improve efficiency and satisfaction amongst patients who are trying to start and maintain a diet strategy as a way to improve their GI symptoms.” Watch now

Charles N. Bernstein
When combined with mesalamine therapy, curcumin, a natural phytochemical derived from turmeric, was superior to placebo in inducing clinical and endoscopic remission in patients with mild-to-moderate ulcerative colitis, according to results from a double-blind randomized controlled trial.
These investigators “have tackled an important therapeutic need in UC, a well-tolerated, inexpensive, oral therapy in mild-to-moderate UC, resistant to mesalamine,” Charles N. Bernstein, MD, from the University of Manitoba IBD Clinical and Research Center, wrote in a related editorial. Read more
