Think I have resolved a connundrum

Over the past 5 or so years, while I have been following the principles of a Low Carb Diet, there have been some foods that have spiked me significantly higher than the listings on the label would account for, I also have a meter that seems to be more sensitive to some food component that other meters I have used do not reflect. I have for some time now suspected an added ingredient in the food that is not what I as chief chef and bottlewasher would normally use.

I used to think it was Monosodium glutamate (MSG) which is used as a thickener in gravy and is one of those items that has to be declared in the USA but not in European or UK listings. It is a hidden sugar that gets added to processed meals, and which is often listed as emulsified starch or stabiliser.

But my recent (n=1) experiment has identified another component that gets added as a stabiliser and sweetener that does not have to be declared as such and which is not classed as a sugar or a carb. It is a common substitute for both sugar AND fat so is more useful than MSG, especially with the current search for Low Fat, Low Sugar . Low calorie foods.

My experiment comprised a beef steak with veg which would not normally raise my sugars by much. I repeated the same meal the following night, but omitted the gravy. My results were
With Gravy my pre meal / 2hr PP /4hr PP results were:
With my Navii meter = 6.7 / 9.3 / 6.6
With my Caresense = 5.7 / 7.8 / 5.4

Without gravy the readings were
With my Navii meter = 6.6 / 7.4 / 5.6
With my Caresense = 5.4 / 6.9 / 4.5

The pre meal starting points were both similar, so this reduces error differences due to %age reading systemic effects. As can be deen the gravy seems to be responsible for adding about 1 mmol/l offset to both of the post prandial results on both meters. It also seems to push my Navii readings up by an extra 1 mmol/l which the Caresens ignores. This is an effect I have been noticing on both my Navii and my SD Codefree when compared against my Caresense (and historically my previous meters)

Back to the OP. Gravy contains a component that raises my blood sugar. So I looked up the ingredients, and discovered that number #2 on the list of ingredients is maltodextrin and since ingredients are normally listed in order of importance, it would seem that maltodextrin is a significant player.

I fould this treatise on Maltodextrin which seems pertinent to my connundrum
https://www.hollandandbarrett.com/the-health-hub/food-drink/food/what-is-maltodextrin/

I also discovered that Maltodextrin is also listed as an e number in the range e1400 - 1500 which is allocated to the dextrins as a group. They are all starch derivatives used in the food industry as stabilsers, flavour enhancers, and they are also shown as high GI (range 80-120) compared to table sugar at 69

Now I know why my chow mein dinner the other night spiked me and why chop suey is so deadly. It is not the noodles, it is the sauce.

Remember that these additives are not classed as sugar, so do not appear in the nutritional section as sugars, they are also not classed as carbs. The chow mein meal I had the other night was listed at 10 gm per pack carb, and 0,5 g sugar. Ny Navii registered a 13.4 peak which is way above what I used to register for this same meal in the past. It tasted different, and I suspect it has been doctored to meet some new audience other than weight watchers. Now I know why my faggots or liver + bacon meals are no-no's as are my beef slices in gravy.
 
As a dieter for very many years I have always treated maltodextrin as a sugar. Years ago it was included on a list of hidden sugars that I found in a magazine. Interesting that nowadays it isn't generally thought of as a sugar. Hmmm.
 
Maltodextrin is used as a horticultural insecticide. It is also a major feedstock for e.coli bacterium in the gut. It is also linked to IBS. It is in canned drinks, ice cream, Energy snack bars, peanut butter, chips and crisps. Sauces, and condiments, salad creams, 1000 island dressings BBQ sauces.

I have probably missed a few more out, but those were some things I found in my research. I think the changes to the gut biome are the worrying ones. I have something to blame my flatulence on now (along with the Dapagliflozin of course)
 
The only regulation I can find regarding food label listing of maltodextrin is if the product otherwise does not contain a wheat component, but the maltodextrin itself is derived from wheat starch. This is because the process to make the powder does not remove the allergens.
 
Good that you’ve identified a trigger and answered a conundrum. I’ve long treated maltodextrin as a blood glucose raiser, and frequently warned of such especially when discussing sweeteners, as many commercial brands use it as a bulking agent, thus rendering the actual sweeteners useless for management of blood glucose even if the calorie count still appears favourable (ie the most common motivator for people using sweeteners as a whole). Some pink and yellow packets in cafes come to mind. I’ve seen it listed in discussions on sweeteners for diabetes on several occasions.

Since the GI of maltodextrin is so high, would it be suitable as a hypo treatment? My old ma used to carry Dextrosol tablets for that reason (T1D)
 
Maltodextrin is 4 carbs per gram and absorbed faster than table sugar. Not surprising it causes spikes.
 
Each to their own but this is why I don't eat or drink anything with a list of ingredients. Not because of glucose necessarily but because my body doesn't need any of this junk. There's so much garbage hiding in plain sight on supermarket shelves it's not even worth turning the packet over to look. One item. One ingredient. Done. Only exception I suppose might be bacon, but that gets a free pass because, well, it's bacon.
 
they are also not classed as carbs
Maltodextrin is a carbohydrate and I believe that it does count towards the carbohydrate content of a food. What makes you think otherwise?

Note, there is also digestion-resistant maltodextrin which has been processed so it is not broken down by human enzymes to obtain energy and therefore would presumably count as fibre rather than carbohydrate.

First time I’ve seen you mention bacon in a long time :p
 
Interesting, bit like sucrose vs fructose. This is similar to what they do to make Sucralose. I suspect that food manufacturers will still use the normal maltodextrin simply on cost grounds. If it takes a further processing step with more chemicals, and takes longer to produce, the original one is probably going to remain their choice for a cheap additive.
