Thanks for posting the link to the study, MLP. The link between IBD and diet is so interesting. We've found my daughter's symptoms are very responsive to diet, and she also responded very well to 90% EN with Peptamen.
What still leaves me scratching my head, though, is that the ingredients of the formulas used for EN are not what you'd think would work. The unflavored Peptamen that my daughter used for EN has maltodextrin as its first ingredient, and also contains cornstarch, soybean oil, and guar gum. The first four ingredients of Modulen (used in this study) are glucose syrup, casein, sucrose, and milk fat. It's just strange how in the study's discussion section, the authors talk about how ingredients like maltodextrin, sugars, milk fat, and emulsifiers have been linked to intestinal permeability. (I'm not trying to say that the formula ingredients are bad--they worked really well for us!--but just that they don't make sense to me.)
The study's list of acceptable foods looks a lot like what my daughter ate for her 10% food, but we also found that she did well with low lactose dairy like yogurt, lactose free milk kefir, and cheddar cheese.
