My brother knows a doctor who swears that if you don't eat sugar your Crohn's will get better. Anyone have any experience with that one way or the other?
I wouldnt necessarily word it that way but you can most definately make Crohn's symptoms worse by eating sugar. Here is why:
1. - A major factor in Crohn's disease pathology has to do with overgrowth of microbes in the GI tract. These microbes can be either yeast or bacteria. A happy GI tract has a proportion of each (yeasts and bacteria) in a delicate balance.
- Overgrowth of one or the other can cause problems.
- The best example I can think of offhand are of (sorry guys this probably wont help you much):
- Vaginal yeast overgrowth =
Yeast Infection
- Vaginal bacterial overgrowth =
Bacterial Vaginosis
- Yeast Infection and Bacterial Vaginosis are due to an overgrowth of either yeast or bacteria in the vagina - a happy vagina has both yeast and bacterial species in a delicate balance. If anyone has had either type of infection you know how uncomfortable it can be. Similarly, an imbalance in GI tract microbes can wreak havoc on the mucosa of the gastrointestinal system.
2. The delicate balance in GI tract microbes is complicated. One of the easiest ways to swing that balance out of whack is with sugar.
- I have cultured (grown) countless species and strains of yeasts and bacteria during my career. The one thing that each of them had in common was a preference for glucose (just simple sugar) as a food source.
- I have done experiments where the simple sugar was not given and they were fed with a more complex sugar instead. Most would still grow but they did not grow as quickly because they had to break down the sugar before using it. An example of more complex sugars are mannose, lactose and an even more complex sugar is starch (sorry pasta lovers).
- With complex sugars the microbes have to process it before they can use it. Glucose, the simplest sugar does not need to be processed. The microbes just say "Thank You".
- An easy way to tell how much sugar is in a product is to check the label. Anything that has an "ose" on the end of it is a sugar. For example, glucose, lactose, mannose, fructose, etc. Starch is also a very complex sugar but this trick doesnt work for starch.
A second example of microbial overgrowth occurs iin persons with uncontrolled diabetes. People who cannot control their blood sugar (blood sugar too high) have increased incidence of microbial overgrowth. This can be seen as yeast or bacterial infections of the skin, the mouth (yeast = thrush), the reproductive tract (yeast infection or bacterial vaginosis), fungal infection of the skin (jock itch, athletes foot, etc.), and even the GI tract (I have seen very poorly controlled diabetics have extreme cases of perianal yeast infection).
So, in sum, if you eat too much sugar (especially simple sugars) it can cause microbial overgrowth in the gut (and the vagina and skin too!).
