It occurred to me that my reply could be read as an attack on Andrina for posting this study.
That's not the case. I apologize to Andrina for making it possibly look that way.
I'm actually kind of glad you shared it, because it allows me to vent!
The reason I reacted strongly is that a well-meaning person I know, who is always pushing a vegan diet, sent this to me a couple of days ago. I spent a good bit of time yesterday trying to find out why a supposedly respectable journal felt this one-person anecdote was in any way noteworthy and worth publishing. That's when I found out just how shady some of these journals can be, with authors paying to have their "studies" or "case reports" published. It's nothing but advertising hidden in science journals.
This particular one is advertising from the PCRM (physician's committee for responsible medicine, the group formed by Dr. Barnard - a vegan-pushing psychiatrist by training who wrote up a case report on a single Crohn's patient. That in itself should raise red flags.)
There are case reports out there of practically every dietary change imaginable leading to a remission of IBD. Some of those dietary changes were the opposite of eating plant-based.
As we all know, placebo controlled clinical trials consistently show somewhere near 30% of patients improve *on the placebo.*
I myself have gone in and out of remission multiple times over the years without medical intervention and without any changes to diet. (By many definitions I eat a "plant-based diet," but I'm not a vegetarian or a vegan.)
No respectable gastroenterology journal or IBD journal would have published this.
Plant-based diets may have many health benefits. They may even benefit IBD, but that isn't known. And Dr. Barnard is cherry-picking and misrepresenting the current state of knowledge in order to further his agenda, not to further actual science about
