Framework Matters: Study Links for Safe & Effective Crohn’s Strategies

This post is really a reference guide that includes an outline and framework for thinking about Crohn’s strategies in a differnent way, along with links to a series of studies that go into depth about each area. This is a good place to start research, and a good resource to share with your doctor.

 
“Nothing in biology (nutrition or medicine) makes sense except in the light of evolution”. Dr. Loren Cordain

Intestinal Barrier Function & Leaky Gut:

These studies provide the framework for all the rest. Essentially all modern diseases of inflammation can be linked to a series of mismatches between our genes and environmental factors. The origin of this inflammation starts in the gut with a breakdown in intestinal barrier function.

Below is a simple chart that list the stressors/environmental factors that either increase intestinal permeability directly or damage the balance of the gut flora, all leading to inflammation.

Increasing Intestestinal Permeability

Gluten/Prolamines	Casein	HBC	Stress
Lectins & Saponins	Low Vitamin D	PPI	Sleep Deprivation
Omega 6 Fats	Antibiotics	Alcohol	Endurance Exercise
FODMAPs	NSAIDs	Capsaicin

 

Below is a simple chart that list the environmental factors that either decrease intestinal permeability directly or improve the balance of the gut flora, all leading to reduced inflammation and healing.

Improving Intestestinal Permeability

IBD Diet	Krill Oil	Probiotics & Fermented Food	Colostrum
Proline (Broth & Gelatin)	Curcumin — BCM95	Mutaflor, VSL#3, Lactobacillus paracasei	LDN

Robb Wolf: Paleo & Autoimmune Disease

In August of 2011 I attended Robb Wolf’s final day-long Paleo Solution seminar. Even after reading his book, I must say that I was very impressed. Robb did a masterful job of explaining how putting diet into an evolutionary biology framework allows for a deeper understanding how diet impacts chronic diseases. It turns out that Robb has UC, and his whole journey into the Paleo diet was motivated by his desire to find a better way to treat his own autoimmune disease.

I found this video of Robb giving an overview and he covers it all, with a focus on autoimmune disease starting about 22 minutes in. He references Cordain, Fasano, Leaky-gut, and vitamin D. There is even a nice overview on the importance of omega 3:6 balance and its connection to inflammation that is often overlooked.  Watch the video and also check out his blog at www.robbwolf.com
