I believe the experience is different for different people. Most of us keep a diary where we document the most recent foods we've been eating - and we try to change things to see what affects us and what doesn't. Of course, with IBS, this is an ongoing process, since things are liable to change without notice.
In my case I don't seem to be affected by those particular foods. In fact I treat IBS very differently, so I don't really count.
I have found it depends on how much sugar. For me my symptoms are aggravated when sugar is present. It is similar to people who become hyperactive or nervous. My theroy is that the sugar stimulates the gut and if an allergin is present speeds up a BM, for me this would be wheat or oats.
Brown Rice which is a good source of carbs does not affect most people with IBS and is generally safe.
Asperstame, Splenda and other artifical sweeteners are alright, but moderation is the key. However, I like natural sugar or raw sugar. However, if you drink colas, and other fruit drinks such as Sanapple, you would be surprised at the amount of sugar in these products. Diet/caffenine free colas are what is needed. The double hit of caffeine and sugar is sometimes too much for my system. It just takes time getting used to the reduction
I also found some more research on digestion, water & sugar today. I believe it is partially opinion and partial fact:
Also remember that sugar is hydroscopic, or water-seeking. That's why a high-sugar food like a chocolate bar or dish of ice cream makes you feel thirsty. In someone without diarrhea, drinking a glass or two of water will usually resolve this. However, in someone with diarrhea, sugar's tendency to pull water into the intestines can actually worsen the diarrhea.
This was the same article that went on to say that turning to artificial sugars is not the answer.
In another article, it discussed sugar blocking the colon and preventing the colons ability to absorb water and vitamins/minerals.
Colon inactivity may hinder the movement of waste material along the intestinal track to be eliminated from the body. Eventually, this waste material builds up along the colon walls and prevents the absorption of water and electrolytes.
Id hate to think the multivitamins I take every day are a complete waste of time! I assume some of them are getting through
In addition, it is essential for everyone to drink at least eight 8 oz glasses of water every day. Dehydration is a major cause of constipation and bowel problems. You don't have to be thirsty to be dehydrated. Water is needed to CLEAN OUT TOXINS.
In other words. Too much water is not a bad thing, it will clear out toxins (and remember this is relating to your other organs, bladder, liver etc). Most of the water passes through our bodies very quickly, not passing through the colon.
But excess water is not going to cause an issue with the colon's activity. The colon will do its best to absorb moisture and vitamins as it works, but bad diet and low exercise, will hinder its ability to do its job.
This thread has become really interesting. I concur with the theroy that IBS'ers have to be more sensitive about food, which for me now includes artificial sweeteners. Most of the items in Chewing gum and diet cola and other "suguar" free items contain Aspertaime.
Does anyone have any information for Splenda. There is also another sugar called, and pardon the spelling
White Spetiva. This is sweetener used diabetics, are there any other information on these items.
But the key, as it has been stated before, is moderation. But I would like to know more.
