Well those studies are not great...
I'm not putting forward any arguments about the quality of the studies or even the quality of the conclusions drawn from the studies, That's a whole other issue.....
I'm saying there is plenty of evidence that diet and nutrition play a huge part in this disease.
A few small trials, hundreds of case studies and thousands believable anecdotes testify that diet and nutrition are important.
First of all the number of patients is too low to make any conclusion.
We can conclude that those on the diets had less indication of disease.
We can't conclude why, but we can speculate and design other studies to test those hypothesis.
Unfortunately there is little money in telling people to eat food that nourishes them and to stop eating crap, so there is little money for the studies
“C-reactive protein did not significantly change during study. Mean fecal calprotectin improved from 471 (SD 562) to 112 (SD 104) at week 11 (P = 0.12). Among those with follow-up endoscopy at week 11 (n = 7), improvements were noted in simple endoscopic score for Crohn's disease (n = 1), Rutgeerts score (n = 1), and Mayo endoscopy subscore (n = 4).”
If you go through analysis of the data well, some indicators are missing (what about endoscopic results? calprotectin?
in my opinion indicators are lacking to conclude there is a real remission...)
The OP's statement was “I am a big believer in Paleo/SCD to help with inflammation”
, not that diet cures so you are arguing against a claim that no one has made.
... by the way I apreciate more this Semi Vegetable Diet, which is a kind of japanese regime with Miso etc... compare to some 'Paleo' or 'SCD' diet recommended in some best seller's guru book...
I also appreciate the semi-vegetarian diet as an example of a real food diet prolonging remission, but I took issues with the deceptive nature of it's representation.
I think the SVD study has far more evidence to recommend a paleo/scd/gaps/PHD diet than anything else.
It has no evidence to recommend a vegetarian diet.
It also has absolutely no evidence in it to suggest that a semi-vegetarian (without the quote marks) diet is beneficial.
It is a piece of propaganda
Ive tried SCd and will testify eliminated refined sugar and lower natural sugar helps immensely to reduce symptoms. however, I eat wheat oats and beans, and find much benefits except when beans aren't cooked well, beans are very hard to cook correctly.\
From what i recall the paleo is elimination of grains for good, I don't agree with that because there is beneficial fiber and fibers is the number one most important nutrient, kinda the good bacteria can eat this and reduce inflammation. avoiding yeast is important too I believe. Even scd says to slowly reintroduce certain foods. i may be wrong on that though just mentioning it.
I'm a real believer in fibre too, but less while the disease is active may be beneficial
There is a strong suggestion that reducing bacterial activity will reduce symptoms.
But people disagree on how to interpret studies, and which studies carry more weight than others etc. so elimination and reintroduction is a valuable tool.
Even then some fibres may be beneficial while others are not, it's not just “fibre good”. Paul Jaminet recommends resistant starch, Criss Kressler recommends beans (if tolerated), the paleo mum recommends against psyllium (but I find it wonderful).
There is sooooo much fibre available from other sources and so much indication that gluten containing grains are problematic for many people and that eliminating them can be hugely beneficial that it is just common sense to eliminate them along with all other potentially problematic foods.
If they can be reintroduced without issue all well and good, but it would be incorrect to just assume that the benefit outweighs the risk
”For the purpose of this study the 'semi-vegetarians' (from the links in the original study [20-30]) refrained from sugar[20,23,24], carbohydrates, fast foods, cola,chewing gum and chocolate, western foods (bread for breakfast, butter, margarine, cheese, meats, and ham and sausage), and were encouraged to eat more fruit and vegetables.”
Well, it must have been the sausages then? go team veg, meat is bad!
”“most prebiotics are extracts of plants. Therefore, we thought that a vegetarian diet would be suitable for IBD.”
- a bit of a leap, don'cha think? Maybe 100% fibre (prebiotics) is the next logical step?
“Foods that have been shown to be a risk factor for IBD in or outside Japan, including sweets, bread, cheese, margarine, fast foods, carbonated beverages, and juices, were discouraged. Healthy habits were encouraged: no smoking, regular physical activity, moderate or no use of alcohol, regularity of meals, and not eating between meals.”
- that's a lot to say, lets just call it “semi-vegetarian”,
they will know what we mean......
