RPS - 10 Aug 2007 08:49 GMT I am not the greatest chemist out there, but I do remember that foods contain several kind of "sugars", among them glucose, fructose, maltose, etc.
However, the diabetic narrative is full of glucose and nothing else. Never heard of a "blood fructose meter". :-)
So I am wondering: Are all sugars bad for T2's, or is it just glucose?
Thanks.

I think you are confused. When we talk of blood glucose, we mean blood sugar. This has nothing to do with sugar that we eat.
There is no such thing as a fructose meter, but there is a fructosamine test. This is like the glycoslated hemoglobin AKA A1c but it doesn't track the cells back as far.
In terms of eating, some would say a carb is a carb is a carb. Meaning that say...a slice of white bread is no worse for your blood sugar than the equivalent in spoonfuls of that white powder we call sugar.
Some people find that certain foods affect them badly and they must either never eat these things or eat them in really small quantities. Potatoes are one such food. I personally have no problem with them, provided I watch my portion size.
Sugars in their natural states do not present a problem to the body, other than perhaps raising BG (blood glucose). But when they are extracted from foods and used as a concentrated source, they can present a problem. For instance, high fructose corn syrup. It has been linked to all sorts of bad things. This is not to be confused with corn syrup, which AFAIK has not been linked to anything bad.
For the diabetic, fructose can be bad. However, that is in and of itself. By that, I mean that honey-like stuff you buy in a jar that is labeled fructose. It can lead to heart problems. Nature intended it to be combined with other natural sugars like sorbitol. If you eat a piece of fruit, there will be fructose in it but also sorbitol and other natural sugars. When you eat them in relatively small amounts like that and combined the way nature intended them, they do not harm the body. Might spike your BG, but won't cause other damage like heart problems.
RPS - 10 Aug 2007 10:41 GMT Let me try to clarify my question. I am using the term sugar in chemical sense: a family of compounds of which glucose is a member but so are fructose, maltose etc.
Now, calories are calories. If we consume more than we spend, we'd gain wait. They could come from sugars to be sure, but the phenomenon is not "sugar" specific, it would be the saame with proteins or fats.
The second issue is extra "sugar" in the blood, whose presence above certain levels causes organ damage and other complications. AKA diabetes.
AFAIK, only glucose appears to be mentioned in this context. Although lay people use the term "sugar" informally, it has always been emphasized to me in every professional setting that we are talking about and testing for glucose, not any other kind of sugar. We don't seem to test for or worry about other sugars.
So, my question, why skip other sugars? Would an excess of fructose or maltose in the body not cause organ damage like glucose does?

Would an excess of fructose or >maltose in the body not cause organ damage like glucose does? As Julie explained, you are confusing ingested sugar and blood glucose. And weight and calories are tangential to this; they have nothing to do with the effect on blood glucose in this sense.
Sugar, in any form, whether lactose, sucrose, fructose, glucose or some other -ose, is one of many foods which will cause a rise in your blood glucose levels after your eat (ingest) them. Other foods, particularly carbohydrates will also raise your blood glucose levels.
If you eat sucrose or fructose or starch, your blood glucose rises, you don't get sucrose or fructose or starch in your blood.
You test for blood glucose - but the cause of that glucose in your blood can be any of a wide range of carbohydrates or even, to a lesser degree, proteins.

I can see starches breaking down into constituent sugars, but one kind of sugar turning into another seems a stretch. I am not sure, but are you? Sideways moves are MUCH harder in Nature: it is far easier to extract oxygen from water than to convert nitrogen into oxygen!
Anyway, let's look it up, if body actually converts fructose into glucose.

You want to get a basic biochemistry textbook to get all this stuff straight.
Monosaccharides are sugars that contain one "unit" of sugar. Glucose is the one we're concerned about in diabetes because glucose is the basic sugar that your body uses. However, you're correct that there are monosaccharides other than glucose. And yes, the body converts them to glucose. Glucose is sort of the "base" sugar in biochemistry.
Most of your monosaccharides are 6-ring structures, and yes, the body converts them to glucose. The case of fructose is a bit different because it's a 5-ring structure and therefore a bit harder to convert. It is more likely to be converted to fat than the other monosaccharides.
Most of the things we think of as sugars are disaccharides. Sucrose, common table sugar, is a molecule made up of one unit of glucose and one unit of fructose chemically bonded together. Lactose, the sugar found in milk, is made up of one molecule of glucose and one molecule of galactose (galactose is another monosaccharide).
Starch and fibers are polysaccharides (also called "complex carbohydrates"), which are big molecules containing lots and lots of chains of monosaccharides (mostly glucose). Starch is broken down in the body very easily, which is why it causes a rise in bg almost as fast as dissacharides. Soluble fiber is broken down minimally and insoluble fiber pretty much hardly at all, hence the notion of "net carbs" where fiber largely doesn't count.
The reason we "count" glucose is because the body primarily uses glucose; all the polymers are broken down by the body into the unit monosaccharides and the monosaccharides other than glucose are converted to glucose before use.
jackiepatti@gmail.com - 10 Aug 2007 15:45 GMT > I can see starches breaking down into constituent sugars, > but one kind of sugar turning into another seems a stretch. > I am not sure, but are you? Sideways moves are MUCH harder > in Nature: it is far easier to extract oxygen from water than > to convert nitrogen into oxygen! This is a *very* different thing. Nitrogen to oxygen would be a change from one element to another.
The change from one monosaccharide to another is a change in the rearrangement of atoms in a molecule. The empirical formula for glucose is C6 H12 O6 - most of the monosaccharides have the same empirical formula. Just they are put together in a different order.

The means the body has trouble metabolising 'sugar' in the blood. The culprit is sugar in the blood. Sugar in the blood comes from any carbohydrate.
You should avoid glucose, other sugars, in fact - other carbs. Eating a load of wheat flour will raise you blood glucose level as surely as eating a load of glucose.

>So, my question, why skip other sugars? Would an excess of fructose or >maltose in the body not cause organ damage like glucose does? Diabetes is the difficulty or inability to handle blood glucose. There are two aspects to carbohydrates; what quick effect do they have, and what total effect do they have. What the carbohydrates are, and how they are combined in food with other things, affects the first, but not the second, with few exceptions.
There are simple sugars, double sugars, and compound carbohydrates, which are primarily starches. How fast they are handled depends on how accessible they are to digestive enzymes; glucose needs none. Finely divided starch, as in cooked potatoes "plain", is almost entirely converted to glucose before it reaches the stomach. Fats, proteins, and mechanical problems (whole grains) can slow the accessibility. This is what the glycemic index measures.
Glucose is quickly absorbed. Sucrose (table sugar) quickly breaks down to glucose and fructose; maltose is just two glucose molecules stuck together with a molecule of water removed, so it has an even higher glycemic index than glucose. Fructose has to go through a process before it affect blood glucose.
Lactose (milk sugar) has to go through a digestive process which separates it into glucose and galactose. Many adults, a majority of the world's population of adults, do not have much of the enzyme, and consequently it goes into the large intestine undigested. I do not know how quickly galactose is handled.

My meter doesn't differentiate. It shows equally high readings if I over-indulge - whether it's glucose, sucrose, fructose or plain old starch.
For example, I get much the same peak post-prandial result from a snack of one slice of multigrain bread (starch), or an apple (fructose), or a glass of milk (lactose), or a few jelly beans (glucose). They are all about 15 gms of carbohydrate. The only thing that may vary slightly is the timing of the post-prandial spike.

Neither. VAT (visceral adipose tissue) is bad because it causes the insulin resistance that disrupts euglycemia.
Glucose is good because it is the exclusive fuel of the brain.
It is the dysregulation that occurs because of the VAT (from overeating) that is bad:

You're confusing 'blood glucose' with food sugars & leaving out a whole array of other factors.

Fructose, in particular, isn't the best for diabetics because it is a pre-cursor to the polyol pathway which produces sugars, such as sorbitol, which are responsible for cell damage in the blood vessels and eyes.

Ultimately, various enzyme systems in the body convert almost all carbohydrates (including all kinds of sugars) to glucose. So ultimately 10 grams of carbohydrates is going to be essentially 10 grams of glucose.

Hi RPS , very good question if you ask me :)
Yes you remember that correctly , food contains all kinds of sugars and sugars are chemically related substances of course.
However in the design of the human body glucose got a very special function
: it is used as an energy carrier.This is by design , you can do nothing about it.To use an analogy : in a powerplant a fuel , an energy source , coal , oil , natural gas , wind etc is converted to electricity.In your body carbohydrates , bread , potatoes , vegetables , fat , meat etc is converted to glucose.The glucose is than transported in your blood stream to where ever it is needed.
Both for the same reason : logistic problems.The transport of electricity and glucose is easier.So there are all kinds of sytems in your body to convert things to glucose , to store glucose , to do the glucose bookkeeping
: how much do we have and do we need more of it at the moment. There is a problem : free glucose is a bit of agressive chemical.It reacts with all kinds of proteins.So the transport of glucose takes place in your blood stream at an unbelieveble low concentration which is very tightly regulated by hormones like insulin and glucagon.
Some parts of these sytems are impaired if you have T2D , the glucose concentration in your blood may become too high giving rise to all kind of medical complications : neuropathy ( which I have) , heart- and kidney problems.So a good thing is to keep your blood glucose levels in check yourselve now your body does nolonger do that for you fully automatically
:( Oneway to do it is to keep track of the carbohydrates you eat and check with a bg meter to see what effect they have on you personal.
The checking is of course only effective if you know what to with the outcome.Measuring your bg in itself is just useless.So your second question
: where are the manuals ? is an even better question.Do not limit yourselve to the low-carb books.If you want a good book than here is are a few free ones : http://www.endotext.org/diabetes/index.htm http://www.ncbi.nlm.nih.gov/books/bv.fcgi?rid=diabetes and take a look at the science behind it all at : http://www.ncbi.nlm.nih.gov/sites/entrez hth Gys

Most polysaccharides, disaccharides, and monosacharides can be converted to glucose.
Some amino acids can also be converted to glucose.
Very little fat can be converted to glucose.
Glucose is absolutely required for the brain to function normally while the rest of the body can use alternative fuels (ketones).
Be hungry... be healthy... be blessed:
