It turns out saturated fats from foods like Coconut oils and from animal foods might cause leaky gut.
A recent study published last year but rarely spoken of breaks current trends on leaky gut theories.
"High saturated fat diet increased gut permeability and inflammation."
-- Lam YY et al.
Mice fed the control diet reported better gut microbiota and reduced intestinal permeability than did the mice fed a diet high in saturated fat who also increased inflammation.

The high fat diet was 60% calories from fat, yet only 32% I think it said was from saturated fat. The control diet was only 10%, that means we are lacking a description of about 20% of the fat content in the high fat diet.
I will place my bet that this 20% if from some type of industrial seed/vegetable oil (since that is standard feed ingredients...I think) that is high in omega 6 and susceptible to oxidative damage. This is probably what caused the finding in the high fat group.
Oh yes, and one more thing. They are rats, not people :-)
Also, read the below article, about half way through I reference a rodent study in which the diet was a bit more well defined and they actually found a reduction in leaky gut markers, I know they were alcoholic rodents, but still :-)
Well, that study does it for me. I will NEVER give my mice saturated fats again.
A= "Evidence is now persuasive that the gut may play an important role in inducing adipose inflammation and metabolic disorders."
B="The cross-linkage between gut microbiota, metabolic dysfunction and the immune system is best illustrated in Toll-like receptor-5 knockout mice which develop spontaneous colitis, insulin resistance, hyperlipidemia and increased visceral fat deposition"
C="Taken together the case can be made, see , that obesogenic diets induce gut dysfunction, which may lead to the stimulation of contiguous fat by an adverse microbial load and subsequently results in visceral fat inflammation and systemic metabolic dysregulation."
D="JO and LHS are or have been employed by AstraZeneca." - I wonder if they have some fat loss drug to sell from this "research"
So, take a bunch of mice that are known to spontaneously develop the shits, have insulin resistance, and increased visceral fat, and then they feed them fat and assume that the fat causes their gut flora to go out of whack and blame the fat. No, it's not the wonky genes that were damaged in these mice that spontaneously develop colitis, obesity, and insulin resistance, it's their diet.
So, A+B->C? Or is it:

Riiight. See, there's a lovely bridge between Brooklyn and Manhattan, I can sell it to you cheap, and you could set up a toll booth.. just gimme your credit card number, maiden name, and social security and sign these papers here...
Research shows that leaky gut, inflammation, and related disorders are caused not only by lectins or Omega-6 fats (for example in vegetable seed oils and grains) but also by Saturated Fats. When will Paleo break the dogma and think beyond old habits of eating so much meat? Inflammation is connected not only to leaky gut but also heart disease, cancer, and Alzheimer's. Perhaps a diet rich in fruits and vegetables, and away from meats, is the most appropriate given these discoveries.
