I think it's a stretch to say that diet doesn't affect UC or UP, either symptoms or inflammation. There is data on SCD and IBD-AID diet that demonstrates some effectiveness, in terms of lab parameters and some reduction in meds after the diet. We also have self report data from thousands of people on SCD to add to this literature. Just because there are not enough RCT's on diet, does not prove that it doesn't affect UC. You can add me to the list of people with long remissions and never having to go on corticosteroids or biologics due to diet. Some biologics cost 100,000 per year or per injection so there is significantly more interest in research, promotion and marketing of pharma meds.
This is taken from a review in nutritional issues in gastroenterlogy, 2019. Some of the research is with CD: https://med.virginia.edu/ginutrition/wp-content/uploads/sites/199/2019/08/Specific-CHO-Diet-August-2019.pdf
Burgis and colleagues from Stanford conducted
a retrospective study investigating the effects of
the SCD in maintenance of remission in pediatric
patients with CD over a one-year period.1
They found significant improvements in lab parameters
(hemoglobin, albumin, ESR) with implementation
of the SCD in patients who were treated with and
without immunomodulatory therapy, and overall
patient height and weight also improved. All effects
persisted with liberalization of the diet, with the
exception of weight gain (50% of patients lost
weight when SCD was liberalized). While the study
was small (n = 11 patients), this was the first study
investigating liberalization of the SCD.
Another survey-based case series of 50 patients
with UC, CD, or indeterminate colitis from Rush
University Medical Center demonstrated that
66% of patients reported complete resolution of
IBD symptoms on the SCD after an average of
9.9 months.7
The majority of these patients were
adults, but pediatric patients were also included.
On average, the diet was also rated to be 91.3%
effective in controlling acute flare symptoms and
92.1% effective in maintenance of remission of
IBD
After 3 years of full remission, I'm in the middle of a flare and until I went back to SCD fully (no grains, etc), I wasn't able to manage the bleeding despite daily mesalamine enemas and balsalaside. I upped the enemas to daily, but it wasn't enough without the addition of the SCD diet. The two combined seem to be helping with bleeding, formed stools and mucous (will post in a week with an update). The last 3 years I added some gluten free grains to SCD (oatmeal, brown rice) so I wasn't doing it fully. At minimum, eliminate processed foods and try gluten free if you don't want to do full SCD.
