That extra ingredient in processed foods that’s making a BIG difference

Microbial transglutaminase the hero & the villain, of processed foods

img-2

Microbial transglutaminases are pop up in everything………. from pastries, to polony, but they’re not listed as an ingredient. Maybe it’s time they should be ?

You’re health conscious or maybe, you’re suffering from a health “crisis”.  So, your first response to a food product, on the shelf, is WHAT IS IN IT ?

Will it work for me ?  Or has it something, that is problematic…

Reading food labels

For me, I always pay attention to the amount of carbohydrates, in the product, since as someone who is insulin resistant,  I know, carbs are my kryptonite.

But, what about the things, NOT listed ?

These include

  • food pollutants, they’re not deliberately added, but, they’re there. Examples persistent organic pollutants and microplastics
  • Enzymes used in the manufacturing process

These aren’t often talked about, but a couple of researchers, from a German based think tank, think they should be.  The enzymes, of concern  are  microbial transglutaminase, sometimes referred to as “meat glue”.

Microbial transglutaminase

It is considered SAFE and widely used, in food production, it pops up in everything………. from pastries, to polony.

It’s estimated that the average person, in the Western world, consumes around 15 mg/day.

a polony, a pretzel and a tube of low fat yoghurt

If you scrutinize those food labels, it’s NEVER listed as an ingredient.

Because, it has GRAS status i.e.  generally recognized as safe and as such, manufacturers are NOT required to list it, in the ingredients, because, it’s NOT an ingredient, but a processing agent.

Besides, the amounts of tiny.

What’s a milligram between friends

An individual product might have a mg or two, at the most.  A milligram, is thousandth of a gram.  And a gram, is something you can barely see.

So, what is the fuss ?

Well, this is the standard response.

Food manufacturers LOVE it and regulatory authorities, aren’t worried.

After all – it’s 100 % natural and, it’s been part of biology, since the beginning of time….

Old friends

You see, transglutaminases, are a family of enzyme, found in pretty much, every living creature. We’ve got them, the plants and animals, we eat have them, so do the bacteria, fungi and viruses, living in out gut.

They’re ubiquitous.

And they do,  pretty cool chemistry.

Biology’s bostick

They “stick” things together – specifically, they “stick” a lysine,  onto glutamine, creating a VERY strong bond, which is hard to break down.

mother nature's bostick

The “stickiness” it what food manufacture’s LOVE.

Transglutaminases can be thought of as, the GLUE, that holds processed foods together.

They  improve

  • palatability
  • texture
  • shelf life

They  even, decrease calories.  Yah !

And a little goes ALONG WAY.  It’s the enzyme way.

Enzymes have utility

If you remember from high school biology, the definition of an enzyme, is that it is a catalyst i.e. it makes reactions happen, but is not used up, by the reaction.

So although 1 mg, is quite literally a drop, in the ocean.

1 mg, can do A LOT of chemistry.

And every glutamine that is encountered is a possible target.  Every glutamine….

So where do glutamine’s hang out ?

transglutaminase playing my red letter with some proteinsThe short answer, you would be hard pressed to find a protein, that doesn’t have a couple of glutamines, in it.   But, there is one protein, which stands out, for it’s high glutamine content.

Gliadin – commonly referred to as gluten.

It’s the protein, behind celiac disease.

Celiac disease

When someone has celiac disease, their immune system, has taken a particular dislike, to this protein and, at every opportunity, tries to take it down.

Unfortunately, as part of the normal digestive process, gliadin, ends up, being concentrated, in the cells lining, the gut mucosa. Which means, the immune system, keeps taking pot shots, at the cells lining the gut.  The constant bombardment, leaves a wake of destruction.

Terrible tummy aches and nutrient deficiencies follow.

Sometimes the attack, moves beyond the gut.

But, what sparks the immune system’s “hate” for gliadin ?

The trigger

Well, there must be a particular groove, in the pattern recognition system (HLA-DQ2/8) of the CD4+ T cells, to get the immune system, in a frothy.  Not all immune systems have this, so not all immune systems react, to the protein.

But something has to IGNITE the “war”, against gliadin.

Could it be the microbial transglutaminase ?

A growing body of science, suggests, microbial transglutaminase are partly to blame, for the rise in autoimmune diseases,  particularly celiac disease.

Enzyme sculptures

Gluten has 30 % glutamine and less than 2 % lysine, so when a microbial transglutaminase, rubs up against, gluten, it’s going to get busy.

Glue-ing.

transglutaminase reshaping gluten

It will tie the gluten protein, up in knots, creating all sorts of new shapes.  And thanks to the toughness of the newly formed, bonds……….. the shapes, are permanent fixtures.

If the gut, is a little leaky…………..

You’re seriously ugly

The odds, that some of these, alternative shaped, gluten molecules, slips beyond the intestinal barrier and enters the circulation, is high.

If enough of them do.

T cell reacting to reshaped gluten molecules

Sensitive immune systems, GO TO WAR.

And the rest is history……

Beyond gluten

There are other glutamine rich proteins, so gluten is probably the tip, of the iceberg.

One particularly important one, is MUC2 mucin – it is a protein, secreted by the cells lining the gut.  Our own, transglutaminase,  acts on this, helping to create a thick layer of mucus, which our “good” bacteria LOVE.

human transglutaminase making mucin protein

The presence of “high” levels of microbial transglutaminase, in the “wrong” place,  can and does impact the functioning of this important layer.

microbial transglutaminse disrupting mucin layer

Encouraging dysbiosis and other gut troubles…..

This, is a recipe for BAD BODY CHEMISTRY.

“Leaky” guts have been implicated in a variety of chronic inflammatory conditions, including

  • autoimmune,
  • infective,
  • metabolic, and
  • tumoral diseases.

The incidence of all of these conditions is increasing and tracks the adoption of Western diets / the consumption of ultra processed foods.

JERF i.e. Just Eat Real Food

 No matter how vigilant you are, avoiding a non-listed ingredient, is going to be a challenge…. until, food regulations change and they will……….EVENTUALLY.

Protect yourself by opting to eat REAL FOOD, as much as possible.

And go “LITE” on commercial gluten free foods…

fake food the problem

Fake food – it’s killing us softly

Modern food processing techniques mean we’re increasingly eating fake food. The extra and missing ingredients in our diet are making us fat and sick.

Good table manners are a requirement for seed eating

Seed eaters are a big headache for the average plant – so plants have got to fight back. Plants can’t get up and run, so they engage in chemical warfare.

Where have all the trans fats gone ?

The WHO is committed to make the world trans fat free, by REPLACING trans fats, with alternative products by 2023. How safe are these alternative fats ?

It’s one of those classic Catch-22s.

To work properly, CoQ10 needs to get in — and for that, it needs fat.

But if you're on a statin or trying to manage your cholesterol, you're probably avoiding high-fat meals.

So... take the supplement, and waste it?
Or eat the fat, and raise your cholesterol?
OF COURSE this might not be such a BAD THING. Lol. 

😬 That's the bind.

A shiny supplement with a sneaky flaw. Come scout supplements with me — for free.

💊 You swallowed the supplement. 

But most of it didn’t make it past your gut. In fact, 95% of your CoQ10 supplement is likely pooped out.

Here’s why Q10’s size, structure, and your meal choices make a BIG difference in whether it actually helps.

🎯 Get digestible science stories—crafted with care and cartoons—to help you outsmart your symptoms and know more than your doctor (most days).. Hop on my list. The link is in my bio.

A health “nut” (classified as a lean mass hyper-responder) dropped his cholesterol by adding 12 Oreos a day to his keto diet.

Sounds delicious, right? 

But if you’re insulin resistant, this cookie hack could backfire.

Ever wonder why your LDL spikes on keto?

It’s not the bacon. 🥓
It’s your liver — working overtime to fuel your body.

On keto, your cells switch from burning sugar to burning fat.
Your liver responds by sending out VLDL particles — packed with fat.
Once the fat is dropped off, what’s left becomes LDL.

⚠️ And that’s what shows up on blood work.
😱 Cue panic.

But if your liver is healthy, those LDLs are just passing through.
If not? They hang around. That’s when trouble starts.

🎥 Watch to understand the science behind rising LDL on keto — and why context matters.

Is your LDL sky-high… but everything else looks great?

If you’re lean, athletic, and insulin sensitive — you might be what researchers are calling a Lean Mass Hyper-Responder (LMHR).

In this reel, I unpack new research comparing LMHRs to everyday folks. The LDL in LMHRs is often >190 mg/dL — a number that would alarm most doctors — but their CAC scores suggest their hearts are doing just fine.

The takeaway?
LDL might be loud, but it’s not always telling the truth.
The full picture matters.

🎬 This is Part 2 in my LMHR cholesterol series. Follow so you don’t miss Part 3, where we dive into the Lipid Energy Model — a theory that may explain what’s going on in LMHRs (and maybe in you too)
