Tight junctions are important, as they keep the contents of the gut inside the gut and out of the blood. If you read Food Combining: What's THAT all about?, you'll see that during digestion, proteins are broken down into individual amino acids & very short peptide chains*. Amino acids & very short peptide chains are small enough to pass through tight junctions. Peptide chains longer than about 3 amino acids are too big to pass through. See also Physiology and Immunology of Digestion.
Carbohydrates are broken down into monosaccharides, which are small enough to pass through. Disaccharides are too large.
Fats are broken down into glycerol and fatty acids. Glycerol is small enough to pass through. Fatty acids and other fatty molecules such as Vitamin D, Co-enzyme Q10, Vitamin K2, curcumin, berberine etc are transported across.
The consequences of having loose junctions are not good. Chains of amino acids that aren't supposed to pass through the gut wall enter the body and produce an antibody response, e.g. Beta-CasoMorphin 7 and/or Gliadorphin 7. That in itself isn't a problem, unless amino acid sequences in the chains match amino acid sequences in certain parts of the body.
Diseases of autoimmune origin such as Coeliac disease (gut), Eczema (skin), Dermatitis herpetiformis (skin), Psoriasis (skin & joints), Sjögren's syndrome (mucous membranes), Cerebellar ataxia (Purkinje cells in the brain), Multiple sclerosis (myelin sheaths of nerves), Type 1 Diabetes (pancreatic beta cells), Rheumatoid arthritis (joints), Asthma (lungs), Lupus erythematosus (various), Autoimmune thyroiditis (thyroid), LADA (pancreatic beta cells) etc are caused by antibody responses inappropriately attacking parts of the body. Autoimmune diseases can also occur after bacterial & viral infections.
The other day, I found Immune response to dietary proteins, gliadin and cerebellar peptides in children with autism.

In other news....
I had a phone call from mum's GP this morning. Having read my evidence, he's agreed to test mum's serum B12, 25(OH)D and Calcium and give her supplements accordingly. He's also happy with me giving mum a Ketogenic diet and will also advise the nursing home to exercise mum as often as she is able. Result!
I put four cubes of liver pâté out for Sooty & Sweep (I don't know which one is which as they're identical) and a Magpie swiped two of them. We also have seagulls. I put the other two cubes out of sight in a box.
So far, so good!
P.S. What fuel can be extracted from decomposing seagulls?

Hi,
not related, just pondering on DNL. It's said that it doesn't really happen that much, etc. But wait a minute, if the glycogen stores are full it's bound to happen, isn't it?
And unless you're low carb and skip your breakfast your stores are always full.
That's correct. People who are sedentary (and therefore aren't burning much carbs in their muscles) and are eating at or above maintenence calories with a high percentage of calories from carbs will have permanently full glycogen stores and significant DNL. A sign of this is high serum TGs.
Being active drains muscle glycogen stores. Liver glycogen stores drain naturally due to Hepatic Glucose Production.
Congatulations on your evidence etc and its effect on your GP.
All you need to watch out for now is when a dietician visits...... Don't mention ketogenic diets to them. I did once, but I think I got away with it.
Hi chmeee,
Well, mum's GP anyway. He graduated in 2002 (so he's still young and open-minded) and he specialises in Mental Health, so he's an ideal GP for mum.
Dietician? Never seen one of those at the nursing home. Did I detect a Fawlty Towers reference? ;-p
I agree in part.
Let's say after dinner a person has full liver glycogen stores and full muscle glycogen stores as no resistance exercise has been done. I understand your muscle stores are used only when you use those muscles. Walking doesn't count as it is based mainly on fat and probably ingested carbs.
During the night GNG happens but Jaminet says the liver stores are enough for 16 hours fasting. So depending on your breakfast you fill it back up but it's close to being full again. A snack at 11, lunch by then probably full.
I wish I could see some diagrams or equations to see the breakdown of nutrients depending on context.
Do you think intracellular liver fat is impossible to get rid of once there? Jenny Ruhl says so. The Merck Manual is not so pessimistic.
Some people don't have high trigs. I don't think I have ever had over 1. I don't have the results from 2007 when I was fat and eating sweets every day. That would be interesting.
But I think I have apoE4, if only they did genetic testing!
Hi lightcan,
I've had a post brewing for a while now and I think that now is the time to post it. This may turn out be the most important thing that I've ever written.
RE fatty liver: I think that nothing is impossible. Have you seen Does Choline Deficiency Contribute to Fatty Liver in Humans?
Nige.
