Generally speaking, unless you are a diabetic your body can handle glucose and sucrose very well. Sucrose is composed of exactly one molecule of glucose and one molecule of fructose.
Glucose is a simple sugar that everybody can asborb into the blood stream very easily. It is frequently used in a saline solution for intravenous feeding.
As strange as this may seem your body transfers sucrose into your blood stream across the stomach and intestinal wall differently that it transfers fructose alone. The current understanding is that when there is exactly 50% fructose and 50% glucose your body uses the sucrose transfer mechanism. When there is more fructose than glucose your body uses another but slower mechanism to transfer the excess fructose into the blood stream. In some people this slow transfer is impeded and undigested fructose ends up in the colon where is rapidly fermented by colonic bacteria. This is what the breath test was looking for.
Everyone has a fructose intolerance limit. Generally what a negative fructose malabsorption test means is that you did not have difficulty digesting a 25 gram fructose load. This does not mean that you won't have difficulty with 30 grams. My personal tolerance is less that 1 gram 
I am not familiar with Smarty candies but if these are them the ingredients list says it contains:
Dextrose , Corn Syrup Solids - May Contain , Maltodextrin - May Contain , Citric Acid , Calcium Stearate , Artificial Flavors , Red 40 Lake , Yellow 5 Lake , Yellow 6 Lake , Blue 2 Lake
Dextrose is another name for glucose. Corn syrup solids are 88% glucose. Maltodextrin is a long chain of glucose molecules. These are quite safe. I would be suspicious of the remaining ingredients.
If you look at the diet that I posted yesterday that is being used to help IBS suffers that have inflammatory bowel disease you will see that artificial flavouring and perservatives are on the avoid list.
Good luck

I have only been on this diet for a week...things are already started working....I am using Benefiber in chamomile tea at night and I started that 'foul' gas too...I thought it was my body trying to regulate and get rid of the bad stuff...and that the benefiber along with the other soluble fiber from food was pushing it out...what do you think?

The link between fructose malabsorption and wheat through fructans is still under investigation. Some malabsorber can eat wheat others have to moderate thier intake

Here is a link to a article on dietary management of fructose malabssorption

It is a breath test. Unfortunately, it only tells you if you can or cannot handle 25 grams of fructose. If you can't the test won't tell you how much you can handle. You have to determine this for yourself. Also, the breath test is prone to false negatives i.e. your test is negative but you are still a fructose malabsorber. The simplest test is to reduce your consumption of free fructose for 3-4 weeks and see how you feel.
Good Luck

I am reducing sugar to try to see if I have an abundance of bad bacteria. Something is telling me yes. I am also taking a probiotic for this now. One other reason I have noticed extra stinky gas before is from being a little C for a while. I up my acacia and fluids and it usually works out, but this time the smell is different and makes me think bacteria. Also I have been watching "You are What You Eat" on BBC and that dr. recommends no sugar and people always lose their gas.
--------------------
IBS-A for 20 years with terrible bloating and gas. On the diet since April 2004. Remember this from Heather's information pages:
"You absolutely must eat insoluble fiber foods, and as much as safely possible, but within the IBS dietary guidelines. Treat insoluble fiber foods with suitable caution, and you'll be able to enjoy a wide variety of them, in very healthy quantities, without problem." Please eat IF foods!

Thanks for all the replies. I'll look through all these links and see if I can make heads or tails of what I'm eating. I do have sugary things but usually it is table sugar/brown sugar. I need to read the list about fruit though...I notices today that I had a few grapes on an empty stomach (passing by them on the table) and less than 10 minutes later, stinky gas.  Not sure if there was a conncection. I can usually tolerate whole wheat products in moderation, but it could be the bagels that I have. It seems like when I get them from a different place, they are made differently and the ingredients don't agree with me (no d attacks, just foul gas). I can totally relate to all of you...It's awful, isn't it?

I am very interested in the information you posted about fructose intolerance. After all these years and visits to the Mayo Clinic and GI Docs I have NEVER heard of this. I am starting to think this could be part of my problem, as I cannot seem to get rid of my gas unless I eat practically nothing, use Miralax at night and a glycerin suppository at least twice during the day. The only way I can get rid of gas, pain and bloating is to empty everything out of there...and despite my diet changes, I am horribly C and continue to have symptoms.
At this time I eat only plain proteins, rice, cooked non-gas producing vegetables (primarily mashed up spinach and pureed winter squash,) peanut butter (I was adding honey to it but have stopped), bananas and some papaya.
Fat and caffeine does not bother me at all and I know they are both supposed to be triggers for IBS.
I am totally lactose intolerant, I feel I have a problem with gluten (or could it be the fructans?), fiber and now I am wondering about fructose. To add to the complication, I have dry mouth syndrome so I chew a lot of gum. I know that sugarless gum has sorbitol in it so I try and chew more sugared than sugarless, but I am not sure if that is any better.
Syl, I am wondering what your diet looks like? Do you eat fruit? Do you eat gluten-containing products? I know you had D and I am C but I would really like to know how you manage your fructose intolerance in real life.
I had a Hydrogen Breath test for bacterial overgrowth, which my doc interpreted as negative. Is the fructose intolerance test different or can something about fructose be interpreted from the test I already had?
Thanks in advance.

It is strange they never tested you at the Mayo Clinic. On this web page on their web site they talk about fructose intolerance. Unfortunately they also have a couple of ambiguities in the notes because sugar (beet or cane) is not a problem fructose malabsorber but is a problem for hereditary fructose intolerance (a rare genetic disorder). It is also listed as one of the tests for chronic constipation on this web page,
My diet is very simple and basic.
Breakfast: oatmeal with 1/4 banana or 1/2 kiwi (deseeded) and brown sugar
Lunch: mildly curried 1/4 chicken breast & 6 shrimp OR 1/2 small grilled chicken breast with carrots & zucchini and 1/2 cup reheat white rice.
Supper: chicken, bison, fish, seafood or pork tenderloin with carrots, zucchini or beets and rice, potatoes or pasta.
I eat gluten containing products. I moderate the amount of wheat products I eat to about the equivalent of 3 slices of bread per day. I don't each onions or Jerusalem artichokes because of their high fructan content. Also, I don't use any supplements or dietary aids especially those containing inulin or FOS (these are fructans that I cannot tolerate even in small amounts).
For the hydrogen breath test for SIBI you likely drank a liquid contain lactulose. For the fructose test you would drink a liquid containing about 25 grams of fructose -- this is equivalent to one soft drink which contains 25-40 grams of fructose from HFCS. The problem with this test is that it only tells you if your fructose malabsorption occurs at the level of a 25 gram fructose load. If you are positive it does not tell you how much fructose you can actually tolerate. This you have to determine by experimenting. Also, the test has a high rate of false negatives. The best test is to remove foods with high excess free fructose for 3-4 weeks and see how it effects you.
I use the article referred to on this web page and the USDA and Fenili databases as my excess fructose food guides.
Good luck
