Many of us may recall our parents encouraging us to eat our broccoli, but we were probably not aware of how farsighted their demands may have been. After all, broccoli is one of the "wonder foods" that is believed to be particularly good for us due to its high concentration of fiber, nutrients, and antioxidants.

Now, a new study has revealed that extracts from broccoli, as well as bananas, may be helpful in treating stomach problems, including Crohn's disease. The research focused on the fibers of broccoli and bananas as a way to help boost the body's own natural defenses against stomach infections.

Crohn's disease often affects the lower part of the small intestines, resulting in inflammation, though it can occur anywhere from the mouth to the anus. It is part of a larger group of disorders known collectively as inflammatory bowel disease, which also include ulcerative colitis.

Previous research had shown that people who suffer from Crohn's disease have a significant number of E. coli in their intestines that are described as being "sticky." This seems to coincide with a compromised ability to fight off undesirable bacteria from invading the gut. With the help of special cells (M-cells), these bacteria penetrate the gut wall and lead to chronic inflammation.

The purpose of the study was to see if dietary choices could improve this situation. What they found was that the soluble fiber of plantains actually prevented the uptake of E. coli in the gut. Interestingly, polysorbate 80, which is an emulsifier commonly used in processed foods, had the opposite effect to the fiber and helped the bacteria move across the intestinal wall.

The findings are particularly relevant in light of the increasing prevalence of processed foods in the diets of many people the world over. While a direct connection between processed foods and Crohn's disease has not been established, the disease tends to affect people more commonly in developed countries where dietary choices tend to favor processed foods while avoiding fiber. In fact, the condition is on the rise in areas that are increasingly embracing the Western Diet.

The research therefore suggests that healthy eating in conjunction with limiting the consumption of processed foods might be an important part of maintaining good intestinal health and by extension, preventing and treating conditions like Crohn's disease.

Crohn's disease can affect people of all ages, though it tends to occur in young adults. The exact cause is not known, but it is believed to result from a complex interaction between a person's genes, environment (including diet), and immune system.

It has been estimated that nearly one million Americans suffer from either Crohn's disease or ulcerative colitis, and males and females are affected equally. 10% of those affected are under the age of 18.
