Dynamic Neural Retraining System: Can DNRS Work for IBD?

Alyssa Luck · May 5, 2022 · Leave a Comment

Summary: The Dynamic Neural Retraining System was created by Annie Hopper to heal herself from severe multiple chemical sensitivities (MCS), and since 2008 has been widely used by others with MCS and other “mysterious” chronic illnesses such as fibromyalgia, chronic fatigue syndrome, and even long-COVID, with seemingly miraculous results. The program is built upon the premise that at the root of all these illnesses is a maladaptive brain response to environmental stimuli, causing the body to react as if harmless stimuli are life-threatening. Although DNRS is not widely used or marketed for IBD, evidence indicates that maladaptive nervous system responses are likely a component of the disease, and at least one IBD patient has reported success using DNRS. Although DNRS is not designed with IBD patients in mind, the principles it teaches may very well be the missing piece for many people who have tried just about everything else.

The Dynamic Neural Retraining System, or DNRS, is one of those programs that appears to toe the line between “this is totally miraculous” and “this is total bullshit.” How could someone possibly go from, say, being wheelchair- and house-bound, and only able to eat a few foods, to being totally and completely healthy, just by doing some mental exercises?

It sounds like magic, but this is the promise of neuroplasticity. It’s not easy, but it’s powerful. And for many with ulcerative colitis or Crohn’s disease, it could be the missing piece – the reason that all of the drugs and diets and supplements haven’t worked, despite great effort and dedication.

Vegan Diets for Ulcerative Colitis and Crohn’s Disease

Alyssa Luck · Mar 16, 2022 · Leave a Comment

Summary: Vegan diets are one popular intervention for IBD, and for good reason – a well-designed vegan diet may confer beneficial effects on intestinal health via modulation of the microbiome, increased nutrient density, and elimination of food irritants. However, diets completely devoid of animal products are not viable long-term for the vast majority of people, and nutritional deficiencies are a serious risk. All the potential health benefits of a vegan diet can still be leveraged within an omnivorous diet, but for those who are vegan for ethical or sustainability reasons, careful supplementation or strategic inclusion of certain nutrient-dense animal foods (such as bivalves) are potential options for avoiding some of the pitfalls.

It is well known that high intakes of meat have been associated with IBD (example source; there are many!). And while yes, these are epidemiological studies and no, correlation does not equal causation, I’d consider it a bit disingenuous to brush off these results as a mere artifact of the “healthy user bias” (as many in the keto, carnivore, and paleo communities are wont to do).

I’ll say right at the outset that, on the basis of anthropological, biological, and other scientific knowledge and data, I don’t believe a strict vegan diet to be viable for the vast majority of humans. That said, many people have anecdotally had astonishing success managing their IBD with a vegan diet, and considering those experiences in light of the epidemiological evidence I mentioned above, I think it would behoove us to pay attention to what this information could teach us about the disease processes involved in IBD, and how to best address them.

Nutrition for IBD

Alyssa Luck · Mar 14, 2022 · Leave a Comment

This post is part of the IBD Index. I plan to flesh out the topic of nutrition for IBD (arguably the only topic I’m technically qualified to speak on, on the basis of formal education) in far greater detail as soon as I’m able, but for now, this page will serve as a placeholder and a gentle reminder that ensuring adequate nutrition is of the utmost importance when dealing with chronic illness.

This isn’t “diets for IBD.” IBD diets are, more often than not, more about what you don’t eat than what you do. This page is about nutrition: making sure your body has all the nutrients – both macro and micro – that it needs in order to function, grow, and repair. This is, after all, the entire reason we eat food to begin with, but that fact is often forgotten amidst frantic attempts to quell symptoms by eliminating foods.

The Specific Carbohydrate Diet (SCD) for IBD: Everything You Need to Know

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: The Specific Carbohydrate Diet is an increasingly popular dietary intervention for IBD patients that involves limiting dietary carbohydrate to monosaccharides, or simple sugars. In practical terms, this involves eliminating all sources of starch, as well as sugar (sucrose) and lactose. It has anecdotally been extremely helpful for a variety of digestive issues, and some published clinical research is beginning to accumulate suggesting benefit for IBD patients, although the best-designed trial thus far does not demonstrate any benefit over a “Mediterranean” diet. Further, the scientific theory underlying the SCD principles does not stand up to our current understanding of the role of intestinal bacteria in IBD, and more importantly, does not support the “fanatical adherence” called for. Ultimately, the diet has helped a great number of IBD sufferers and may be right for some people, but there are likely other dietary and lifestyle approaches that could deliver similar or greater benefit with less restrictiveness and easier-to-follow guidelines.

Ah, the Specific Carbohydrate Diet. I’ll save my experience with it for another time and keep this page as objective as possible, but as a disclaimer: this is the diet I stuck to religiously for the vast majority of the ~3 years between being diagnosed with UC in 2008 and having my colon removed in 2011. (So at the very least, I’m writing from a place of experience!)

From the looks of it, the diet has only grown in popularity since that time. Even giant online health websites like WebMD, VeryWellFit, and Healthline are chiming in about it. (You don’t need to go read those pages. Just keep reading this one; it’s better.)

This post will give you an overview of the SCD, where it came from, the rationale behind it, pros/cons, and things to watch out for. I also link some relevant resources, and at the bottom of the post (as usual) you’ll find a literature review of sorts. An annotated bibliography, if you will.

The Science Behind the Specific Carbohydrate Diet (SCD): Brilliant or Bunk?

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: In her 1987 book Breaking the Vicious Cycle, Elaine Gotschall proposed the hypothesis that digestive diseases – including IBD – are perpetuated by a vicious cycle of carbohydrate malabsorption, bacterial overgrowth, and intestinal injury, and can therefore be resolved by removing specific carbohydrates from the diet to break the cycle. Much of her research was quite prescient, but key claims fail to stand up to scrutiny, and the science does not support adherence to SCD principles. A modern look at Gottschall’s hypotheses reveal that modulating the intestinal bacteria through diet is indeed as important as she suspected, but that strategies other than the SCD are better able to accomplish that goal.

This article is a deep dive into the science behind the Specific Carbohydrate Diet, and is a companion post to the high-level summary post: The Specific Carbohydrate Diet (SCD) for IBD: Everything You Need to Know.

The Specific Carbohydrate Diet as laid out in the 1987 book Breaking the Vicious Cycle (BTVC) by Elaine Gotschall is respectably science-driven. She lists dozens of references in the back of the book to support her recommendations (which is impressive considering she was conducting this research in the pre-internet era), and the book itself has been cited in the literature over 100 times. The SCD is also increasingly showing up as an intervention in clinical research, first in case studies and more recently in a large randomized controlled trial.

I said this in my main post on the SCD, but in many ways, Gottschall was truly ahead of her time with the theories she lays out in her book, although of course she leaned heavily on the work of Dr. Haas. In researching this post, I was struck by how relevant her work still is, and how many modern lines of inquiry flow naturally from her hypotheses.

That said, the big wheel of science keeps on turning, and there’s much to be critiqued in BTVC, with quite a few issues that are – in my view, at least – highly relevant to patients. When you have a dietary protocol with rules that are as specific as those of the SCD – and when the diet originator claims they must be followed with “fanatical adherence” – you gotta make sure they stand up to scrutiny, right?

Is the Low-FODMAP Diet Effective for IBD?

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: A low-FODMAP diet, which is a common intervention for IBS, is being increasingly studied in IBD patients. Unfortunately, the diet does not currently show efficacy for reducing inflammation, but has been shown in clinical trials to be effective at managing functional gastrointestinal symptoms in patients whose disease is in remission. Although a common concern with low-FODMAP diets is potential adverse effects on the microbiome from removing fermentable substrates, its actual effects on the microbiome in practice have not yet been clearly characterized, with inconsistent results across studies. For those who wish to support their microbiome on a low-FODMAP diet, resistant starch and Sunfiber are good low-FODMAP prebiotic options.

The low-FODMAP diet is somewhat unique among IBD interventions because it promises to intervene in the common but oft-overlooked situation of continuing functional gastrointestinal symptoms even in the absence of inflammation.

I cover the basics and practical aspects of a low-FODMAP diet in The Low-FODMAP Diet for IBD: Everything You Need to Know. In this article, I take a deep dive into all the evidence regarding the effectiveness of a low-FODMAP diet for IBD, both from the perspective of reducing inflammation and managing symptoms. I also address the most common concern about a low-FODMAP diet: its effects on the microbiome.

The Low-FODMAP Diet for IBD: Everything You Need to Know

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: The low-FODMAP diet originated in 2005 out of a hypothesis about IBD pathogenesis, but quickly became a go-to treatment for IBS. For IBD, the diet has found its niche as an intervention for addressing lingering functional gastrointestinal symptoms in patients whose IBD is in remission. For this purpose, the diet has demonstrated successful symptom reduction in clinical trials, but no evidence yet indicates that it is helpful for quelling inflammation. The biggest risk associated with a low-FODMAP diet is adverse effects on the microbiome from depriving it of fermentable carbohydrates, but this can be addressed by including low-FODMAP prebiotics (such as Sunfiber and resistant starch) and by reintroducing FODMAP-containing foods as tolerated.

Hypnotherapy for Ulcerative Colitis and Crohn’s Disease

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: Hypnotherapy is a mind-body therapy that may have therapeutic potential for IBD, although it’s a bit less practical to implement at home compared to other mind-body therapies such as meditation. Thus far, clinical trials in IBS have shown more impressive results than those in IBD, but there is some preliminary evidence that hypnotherapy could help maintain remission in UC patients who are already in remission, and reduce heart rate and inflammatory markers in those with active disease. The precise mechanism of action behind hypnotherapy remains to be elucidated, but the research of Robert Becker into the electrical systems of the body provides some fascinating glimpses into what may be happening to the mind and body in states of hypnosis.

Meditation and Mindfulness for Ulcerative Colitis and Crohn’s Disease

Alyssa Luck · Mar 14, 2022 · Leave a Comment

Summary: Meditation and mindfulness are becoming increasingly popular in the health sphere, and rightly so – ample evidence indicates that these practices are extremely beneficial for health. However, as far as their practical efficacy in managing IBD, the jury is still out. Clinical trials in IBD have fairly consistently shown improvements in overall quality of life, but thus far haven’t demonstrated improvements in flare rate or severity. That said, trials in a variety of patient populations have shown that mindfulness appears to down-regulate NF-κB activity, reflecting an overall less inflammatory gene expression profile. Other evidence supports the idea that mindfulness markedly changes how the central nervous system physiologically responds to stressors, including down-regulation of sympathetic nervous system and HPA-axis activity. Taken together, it appears likely that mindfulness could confer more measurable benefits with regards to inflammation and disease progression in IBD over the long term.

Mind-body medicine is currently an area of particular research focus for me, so you can expect this post to be expanded and updated in the near future! Follow me on Instagram for personal content related to mind-body medicine, as well as snippets of interesting research that might not make it into a blog post.

Mindfulness is one of those golden health practices that I call “no brainers” – in other words, you have nothing to lose and everything to gain. At the outset, I can say that I’d recommend some type of mindfulness practice to every person with IBD, almost without exception (and anyone who knows me knows that I’m not usually in the business of recommending things).

So if you want to learn more, read on. Otherwise, save your time and go meditate!

Hyperbaric Oxygen Therapy for Ulcerative Colitis

Alyssa Luck · Mar 14, 2022 · Leave a Comment

This article is part of the IBD Index. Last updated on March 14, 2022.

I initially focused on either UC-specific or general IBD evidence, but hope to eventually update this post to include Crohn’s-specific evidence as well.

What is hyperbaric oxygen therapy?
Hyperbaric oxygen therapy (HBOT) involves inhaling 100% oxygen at greater than atmospheric pressure for a period of time, usually between 30-120 min. This is done either in a single-person pressurized chamber, or in a multi-person room where oxygen is delivered via hoods or masks. Treatments can take place in hospitals or outpatient clinics, or at home with soft hyperbaric oxygen chambers (although the efficacy of soft chambers is debated).

HBOT is most commonly used for refractory wound healing in situations like advanced diabetes, severe burns, and skin grafts, but it’s being investigated for therapeutic potential in a number of different conditions (including IBD!). Few clinical trials have been conducted so far, but the ones that have (plus the documented case studies) are extremely promising (see references below).
