Keep 'em tight, Part 2.

Keep 'em tight was about the ramifications of excessive gut permeability, a.k.a."Leaky Gut".

Almost as an afterthought, I added to that post a link to Physiology and Immunology of Digestion. As this article is interesting & informative and since only 706 people have read the first post since it was published (the link was added quite some time later), I thought that I'd give it another airing, with a picture to make the post more attractive.

Doctor, every time I do *this*, it hurts!

The correct response is either:-

1) Go to hospital and get that broken finger fixed, or
2) Stop doing *that*!

There seem to be a lot of people out there who are having problems with wheat gluten (gliadin), casein and other proteins. As Matt Lalonde said in The Science Behind the Paleolithic Diet, some proteins are harder to digest than others.

Here's a hard to digest protein:-


It's raw albumin (egg white protein). As mentioned in As sure as Eggs is Eggs....., raw albumin is poorly absorbed, compared to cooked albumin. To digest the above protein requires peptidase enzymes (pepsin, trypsin and chymotrypsin) to break the peptide bonds. This has to be done from the outside inwards, so a large, heavily-folded protein takes a long time to break down into individual amino acids. Cooking albumin changes the 3-D structure - this is called denaturing. Cooked albumin digests much faster than raw albumin, which is why it's much better absorbed. Cooked proteins are generally faster to digest than raw proteins, unless they're burned to a crisp on a barbecue!

In a person with a healthy gut, partially-digested proteins are not absorbed, as the molecules are too large to pass through the tight junctions in the small intestine. They just ferment, producing malodorous wind. In a person with impaired gut permeability, partially-digested proteins pass through the loose junctions and get into the blood, provoking an immune response. This is not good, so Keep 'em tight.

People who suffer ill-effects after eating certain proteins may either have the wrong genes (e.g. coeliac disease), or have impaired gut permeability. The former isn't fixable but the latter may be. In the meantime, if eating "X" hurts, don't eat "X"!

The usual suspects.

On Facebook, on message boards and in conversation, I often see and hear:-

1. I'm down in the Winter/I keep getting infections/I have allergies/I have aches & pains.

2. I'm up & down a lot.

3. I'm down/I'm anxious/I can't sleep/I get restless legs/cramps/menstrual cramps/muscle spasms/lung spasms/migraines.

4. I've got inflamed or painful joints/skin/guts/lungs/w.h.y.


1. Vitamin D insufficiency/deficiency is widespread by the end of Winter (~90% of people have serum 25(OH)D less than 75nmol/L or 30ng/mL) due to insufficient sun exposure (or sun exposure through glass) during the Summer. A safe & effective dose is 50iu of Vitamin D3 per kg weight per day. See Randomized comparison of the effects of the vitamin D₃ adequate intake versus 100 mcg (4000 IU) per day on biochemical responses and the wellbeing of patients & Vitamin D.

2. Modern diets are lacking in long-chain omega-3 fatty acids (EPA & DHA), as many people don't eat any/enough oily fish. Tinned tuna is not a good source of omega-3 fatty acids. See Omega-3 fatty acids and major depression: A primer for the mental health professional. Women of reproductive age can take flaxseed oil, if they don't like oily fish, or take about ten 1,000mg fish oil capsules each day. Women not of reproductive age & men need to supplement with vegan DHA in addition to flaxseed oil, if they don't like oily fish or fish oil capsules.

3. Diets low in greens are low in magnesium. Excessive stress and/or alcohol consumption increases loss of magnesium in urine. Magnesium deficiency can cause all of the above symptoms. Epsom Salts are a very cheap source of Magnesium. 1 level teaspoonful/day (~4g/day) of Epsom Salts (spread the dose out over 24 hours to prevent it from having a laxative effect by dissolving the crystals in 250ml of warm water, then adding the solution to drinks to spread the 250ml out over 24 hours) provides ~400mg/day of Magnesium. See Magnesium and the Brain: The Original Chill Pill and  Magnesium in Man: Implications for Health and Disease.

4. Vitamin D and omega-3 fatty acids are anti-inflammatory. Inflammation that's worsened by stress and/or anxiety may be alleviated by magnesium.


Difficult-to-treat health problems such as depression are often multifactorial (with physiological AND psychological causes), so it's advisable to try 1. 2. and 3. (with your GP's consent). If you get improvement, you can discontinue supplements one at a time with a washout period of two months for 1. and 2. to see which supplement(s) was/were effective.

Here's a picture to go with the title.

And finally...
I'm so glad that I don't work with David Thorne.

Keep 'em tight.

Wheel nuts? Nope!

I'm referring to Tight Junctions. As mentioned at the end of Wheat? Oh, dear! , 10% of people who are healthy enough to donate blood have gut walls permeable enough to let gliadin fragments pass into the blood.

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?

Magnesium: Just as important as Calcium.

Suffering from anxiety/depression? Can't get to sleep? Suffering from night cramps/restless legs/menstrual cramps/muscle spasms/asthma/migraines? You may be deficient in magnesium. See Magnesium and the Brain: The Original Chill Pill , Magnesium and the Ketamine Connection , A case of oesophageal spasm, and the ‘unproven’ treatment that helped it and Around the Web; and Menstrual Cramp Remedy.

After Vitamin D and Omega-3 fats, magnesium is the third nutrient in which people are likely to be deficient. Processed foods are low in magnesium. Diets low in green vegetables are low in magnesium, as chlorophyll has magnesium at the centre of the molecule. For a list of the 999 richest sources of magnesium per 100g serving, see http://nutritiondata.self.com/foods-000120000000000000000-w.html. Too much calcium can result in a relative magnesium deficiency.

An optimum intake of magnesium is approximately 50% of your calcium intake. Other sources of magnesium are Milk of Magnesia (magnesium hydroxide) and Epsom Salts (magnesium sulphate heptahydrate). A large amount (~4g) of Epsom Salts taken in one dose acts as an osmotic laxative, but spreading the same amount over 24 hours has no laxative effect. Approximately a level teaspoonful (~4g) of Epsom Salts gives you ~400mg of magnesium. Epsom Salts is as cheap as chips.

Magnesium is also available as a dietary supplement. Magnesium oxide (Magnesia) isn't as well-absorbed as magnesium citrate/amino acid chelate, so take extra if using oxide. See Magnesium bioavailability from magnesium citrate and magnesium oxide. Magnesium can be absorbed through the skin, so adding Epsom Salts or Magnesium Chloride to your bathwater is another option.
