EEN , proximal absorption , Illeum resting & Juicing

[LiteBlueSkies]

If the benefit of EEN is that it is a liquid that is proximately absorbed and allows the illeum to rest , Does that mean that I should Juice and drink vegetables like cabbage , carrots etc., instead of eating the whole food Or would that not let the illeum rest ?

"juicing vegetables" has likely no impact on where these vegetables are absorbed.

That doesn't mean that EN's mechanism of action is therefore proximal absorption, but it's a possibility. It might also just be that EN, because it's a liquid, has certain osmotic effects, affecting motility through the small intestine, in which case juicing vegetables, would be beneficial, I don't know.

Anyway, the reason EN is so easily absorbed is its components.

-Glucose syrup. Absorbed in the duodenum and jejunum.
It's basically glucose with very limited amounts of other sugars like maltose.. Absorption rate is basically the same as glucose, 95% will never reach the ileum.

-MCT. Absorbed in the duodenum and jejunum.
MCT, sometimes the only fat found in EN, is pretty different from the type of dietary fat composition people normally consume. Unlike LCT, MCT is much more easily absorbed. Absorbing LCT is very difficult, it requires extensive enzyme breakdown, bile salts and it first enters the lymphatic system before entering the bloodstream. MCT are immediately absorbed into the bloodstream. My guess is that when people lose fat through these "keto" diets, it has more to do with people simply being unable to absorb the fats they consume, and not because the body has suddenly become adept at burning body fat.

-Protein. Absorbed in the jejunum.
Broken down by the stomach and duodenum, taken up by the jejunum. Type of protein seems to have no effect on EN effectiveness.

It's worth a shot. For me the only type of EEN that worked was Compleat Chicken Garden Blend. Recently I am replicating it at home almost all the time, essentially its puree-ing mango, butternut squash, chicken meat, olive oil, and some spices and salt, with pretty good results. I have my Crohn's in my Terminal Ileum. Liquid easy to digest EEN never seemed to work for me unfortunately, no idea why, my working theory is that for 10 years prior to Crohn's I had IBS-D, and generally was always thin with really fast metabolism i.e. the food I eat would often come out within 2-3-4 hours. I am thinking that I react to EEN the same way, it goes through me so rapidly that it simply doesn't have the time to get absorbed proximally. And I guess thats why these puree stuff work so well, as there are things in it that slow my digestion down. With this I go to toilet 1-2x per day and its not diarrhea.

But it's not as perfect as some folk achieve with EEN - I can get my calpro down to the 100-200 range if I adhere strictly. Probably due to all this fiber etc., its "imperfect". But hey, it made practically all my symptoms disappear and gave me a clear MRE so I guess I will take it. It would be quite interesting for me to one day try EEN (I love their taste, really) with some sort of medication or something that would in parallel slow my digestion down. But I dont know enough about this to know what and how to try.

Thank you, i will look into compleat chicken garden blend and maybe think about making it myself ..right now the best that works for me is ENSURE ...but i eat other stuff with it ...however ..when I eat that alone it really helps .
