Irritable Bowel Syndrome Message Boards

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
