You note that "The doctors don't recommend trying diet for symptom control. Apparently they don't have a study that shows benefits from diet, but I can't imagine that they get nobody showing improvement on this diet."
They're just not looking very hard.

Treatment of Crohn's disease with an unrefined-carbohydrate, fibre-rich diet.
Heaton KW, Thornton JR, Emmett PM.
Thirty-two patients with Crohn's disease were treated with a fibre-rich, unrefined-carbohydrate diet in addition to conventional management and followed for a mean of four years and four months. Their clinical course was compared retrospectively with that of 32 matched patients who had received no dietary instruction. Hospital admissions were significantly fewer and shorter in the diet-treated patients, who spent a total of 111 days in hospital compared with 533 days in the non-diet-treated control group. Whereas five of the controls required intestinal operation, only one diet-treated patient needed surgery. This is in strong contrast to general experience with this disease. Treatment with a fibre-rich, unrefined-carbohydrate diet appears to have a favourable effect on the course of Crohn's disease and does not lead to intestinal obstruction.

[Sugar free diet: a new perspective in the treatment of Crohn disease? Randomized, control study]
[Article in German]
Brandes JW, Lorenz-Meyer H.
Since several studies have shown that patients with Crohn's disease have an increased consumption of refined carbohydrates, the influence of a diet excluding refined sugar on the course of the disease was examined. In a randomised control trial, 20 patients (10 patients in each group) with Crohn's disease were treated for an average of 18 months with two different diets. The patients used in the study had a low or middle activity of the disease. Drug treatment was omitted 14 days before commencement of the study. The first group was treated with a low carbohydrate diet (refined sugar excluded), the second group received a high carbohydrate diet (refined sugar-rich). In patients with higher activities of the disease (activity index 100-200 points), the diet which restricted refined sugar was superior to the sugar-rich diet; in 4 out of 5 patients the disease activity decreased and remained so throughout the study-period. In contrast to this 4 patients treated with the sugar-rich diet had to be taken off the treatment because of increasing activities of the disease. In patients with quiescent disease (activity index less than 100 points), neither of the diets showed detrimental effects. The statistical analysis of clinical and laboratory dates noted during the study period resulted in no significant differences between the two groups.=20

Diet in the management of Crohn's disease.
Workman EM, Alun Jones V, Wilson AJ, Hunter JO.
Thirty-three patients with Crohn's Disease were studied to see if their symptoms were related to food intolerances. Initial treatment to produce remission of symptoms was total parenteral nutrition (20), elemental diet (2) or elimination diet (11). Twenty-nine patients reported specific food intolerances, and 21 of these remained in remission on diet alone, the mean length of remission being 15.2 months. The most important foods provoking symptoms were wheat and dairy products.=20

Crohn's disease: maintenance of remission by diet.
Jones VA, Dickinson RJ, Workman E, Wilson AJ, Freeman AH, Hunter JO.
20 patients with Crohn's disease took part in a controlled trial in which remission was maintained by either an unrefined carbohydrate fibre rich diet or a diet which excluded specific foods to which a patient was intolerant. 7 out of the 10 patients on the exclusion diet remained in remission for 6 months compared with none out of the 10 on an unrefined carbohydrate fibre rich diet (p less than 0.05, Fisher's exact test). In an uncontrolled study an exclusion diet allowed 51 out of 77 patients to remain well on the diet alone for periods of up to 51 months, and with an average annual relapse rate of less than 10%.

NUTRITIONAL THERAPY FOR CROHN'S DISEASE
A paper presented at the Fourth Annual Sympoium on Alternative Therapies
at the New York Marriott World Trade Center
March 28, 1999
Some snippets from that:
"The dietary treatment was administered in a tiered fashion. The initial diet was a grain free, low disaccharide diet (the specific carbohydrate diet, SCD); this was followed for 30 days. If a symptom reduction of 50 percent or more occurred the diet was maintained and nutritional supplementation was begun with fish oil capsules supplying 875 mg of EPA per day and a multi-vitamin/multi-mineral preparation supplying 400 mg of vitamin E, 20 mg of zinc, 200 mcg of selenium, 800 mcg of folic acid. If there was less than a 50 percent reduction in symptoms, additional dietary changes were made on an individual basis. These were (a) complete elimination of all milk derived products, (b) reduction in dietary yeast and monosaccharides, (c) avoidance of all nuts and nut flours, (d) addition to the diet of non-glutenous starches (e.g., rice and potatoes)."
From the results:
"All 20 patients demonstrated a decrease in symptoms and reduction in medication use. Six patients have entered complete clinical remission, discontinued all medication, and maintained remission for five to 80 months. The most rapid response in this category belongs to a 28 year old male who presented with daily fevers of 40 degrees C, bloody diarrhea six times per day, a serum albumen of 2.6 g/dl, ESR of 90 and oxalic acid excretion of 164mg per day, despite the use of azathioprine 100 mg per day and prednisone 40mg per day. This patient achieved complete clinical and laboratory remission during the first 60 days and has maintained remission for three years. For the remaining 14 patients, reduction in symptoms scores were from 90 percent to 40percent (mean reduction of 65 percent)."
So, yeah. There are data to support both safety and efficacy of carbohydrate restriction in the management of Crohn's disease.
(Not that you said there wasn't- I'm just showing how big my brain is!) ;-)
