Curcurbita - you mention you are not a doctor but say, "I suggest this or that". I am curious. Are you a registered dietician with a specialty in digestive disorders? Is your experience coming from studies and research that you have participated in an IBD center?
I am a HUGE fan of registered dietician(s) and feel their voice is often lacking so I am very interested to know if we are lucky enough to have one among us.
This being said, the area of diet as treatment for IBD is still in the infant stage and I don't think anyone really knows enough about the implications of diet on IBD to definitively rule in or out any one diet. Just like some drugs work for some and not others, you can not say this diet works or doesn't.
My daughter for one tried the CDED given our GI is VERY involved in research surrounding diet and was very enthused by the most recent research surfacing around the diet. Alas, it didn't touch her symptoms or disease. He is also very involved in research surrounding the SCD and modified SCD approach. He is well versed in all things micro biome and diet and has the support of a huge dietician department and multiple other pediatric centers also participating in this research. We are VERY deep in our journey with SCD and connected with many other families who have been using it. None of these kids have had a problem with calories and most are gaining weight and doing rather well. My daughter for one has reversed her downward weight trend and as far as mucus goes, well one look in the toilet will tell you that mucus is not a problem for her
Some kids are thriving on the diet alone with no meds, normal cal pro, labs, scopes, biospsies and imaging. I don't think that any of them or their GI's would say that their results are coincidence as IBD in children very very rarely goes into a spontaneous remission. Some kids are on meds and SCD and experiencing remission and there I think it does get cloudy as to what caused remission but the kids are doing great so why rock the boat. Others have declared the diet a fail with regards to remission and have decided to just stick with drugs and are still chasing remission. You say Paleo is good but SCD is so close to Paleo.
With the topic of diet, honestly every one of them has what we all would consider pitfalls and items that make no sense. However, there is at the very least antidotal evidence that they work even if for only clinical symptoms. It is not for us to say one is better than another because just like drugs, some work for some and some for others.
You say you don't generally comment on forums and I don't want to scare you away because we do appreciate all options, however, you present things as fact and do not let us know what lens you are approaching things from. Are you a patient who enjoys IBD research? Are these things you have tried? Are you a parent who has tried these things with your own child? etc. It would really help participants here process the information you are presenting if we knew more of where they are coming from.
Hi Crohnsisct,
I didn't pretend to rule out SCD. I'm sorry if it seemed like that; I wrote a very long message so I couldn'd explain every point as much as I'd like to. Otherwise you would know that I do consider SCD sometimes, it's among my armamentum, but not now.
Yes, I would include SCD in the list of diets to try, since in has a good historial of helping some conditions and it has some anecdotalevidence in its side. However, given that:
(1) it has several downsides, (I'll explain some later below)
(2) it doesn't have a clinical trial on Crohn's disease showing the remission and clinical response rates, as far as I'm aware,
(3) it wasn't developed for Crohn's disease and certainly it doesn't fully agree with the current knowledge regarding the pathogenesis and ethiology of Crohn's disease, which means that better designed diet for Crohn's has better chances to be more complete to address Crohn's (just as evidence shows)
Now, given that:
(4) we do have a diet developed specifically for Crohn's disease,
(5) which does take into account current body of knowledge,
(6) and has shown about 70-80% remission for Crohn's patients, even for those who failed biologics,
(8) and has fewer drawbacks,
Then it's better to try first CDED than SCD.
Does that mean that SCD is useless? Of course not. But if I have to do a bet for my ill son, I'll try to play chances in my favour. Maybe CDED ends up doing nothing and SCD ends up helping him, but we can't know now, and it's less likely.
Regarding the downsides of SCD:
If the kid has the ileum affected, chances are he's not properly absorbing bilis. Fat is different to carbohydrate and protein in that for its digestion we need bilis more than enzymes. It emulsifies fat and allows its digestion and absorption. If the last part of the ileum is inflammed, bilis isn't absorbed and it reaches the colon. Bilis can irritate the colon and worsen the microbiota composition by shutting down some kep beneficial strains.
So if we can't rely on fat, and dense carbohydrates sources such as grains and tubers are out the diet, we can't assure a proper amount of calories in the diet!
Another issue is that, if bilis is excreted, the bilis pool is diminished. Body will run in cholesterol. It impairs immunity and hormones, since lypoproteins have a role in the immune system, and several hormones need cholesterol, such as testosterone.
One more issue is that, since dietary calcium binds to bilis, it means that calcium won't be available for its absorption in its entire way through the digestive tract. Oxalate instead will be, since calcium won't be available to form insoluble salts with it. Oxalate is very well absorbed in the colon, so in the long run the chancesto develop kidney stones are increased.
So those were several examples explaining why he probably cannot tolerate fat. He may do better in a carbohydrate based diet. Yes, it also has downsides. If his sugar skyrockets it's not good for his health nor his immunity. But we can prevent it by eating cooled and reheated potatoes, and combining them with other food.
Eating enough calories is difficult if you reduce your fat intake to a minimum, but it's possible. Eating enough calories if you can't absorb fat and exclude carbohydrates from your idea is even more difficult.
Another issue is that, if I recall correctly, most foods that SCD encourages are rich in fiber. This isn't good in this situation.
CDED has fiber, but mostly insoluble fiber. Resistant starch RS3 and pectin are among the most important fibers for a Crohn's sufferer in order to help its condition, as long as we know. They are key for good health too.
CDED is low in FODMAP and hypollargenic. It also helps: we don't know if he has SIBO or IgM mediated allergies, first due to bad functioning of ileocecal valve, second due to impaired barrier function leading to permeability of dietary undigested proteins.
With all this I just want to justify, in part, why it's better to try CDED first, or EEN, depending on the kid case.
I'm not a huge fan of CDED just as it is. I would modify it a bit. For example, I would exclude egg whites, but not egg yolks, because they are immunogenic. I wouldn't incorporate wheat or other grains, even if the diet encourages so in the later weeks. I wouldn't include tomato given it produces symptoms in a big proportion of Crohn's patients. And so on. But as a whole, it moy be the better diet we have for the average Crohn's sufferer.
In the end, we have our biases, but as a scientist I truly believe this is the best way to play our cards.
Studies show diet is more effective if the colon, and especially the perianal zone, are not affected. This is the kid's situation. Hopefully diet helps him a lot and soon he can find relief.
