The protective role of fiber in question
Colon cancer is the first of its frequency. Its early detection depends on a better prognosis. Thus, we now foresee a mass screening. Its prevention is based on the lifestyle and dietary advice.
Among these, the role of fiber now appears increasingly controversial.
Heredity plays an important role in the development of colon cancer. However, it was able to identify other risk factors such as physical inactivity and obesity. Thus, the exercise and the fight against overweight have a preventive action. About diet, has long recommended a diet rich in fiber.
Controversial effects
The effects of fibresIl is accepted long ago that a diet rich in fiber is a "good thing" that protects colon cancer. This assumption dates back to the early 1970s. In 19691, a missionary surgeon Denis Burkitt noted that rural Africans have much less colon cancer than Westerners. But since then, many studies have examined the relationship between fiber and colon cancer, and the least we can say is that their conclusions are at least discordant ...
First challenge of importance, study2 food habits 88,000 women over 16 years! After their investigation, the authors found no preventive effect of fiber vis-à-vis the development of colorectal cancer or polyps. Finally in 2000, two studies3, 4 on diets and supplements rich in fiber could not establish protective properties ... When the prestigious journal The Lancet published a article5 assigning fiber a deleterious role in the recurrence of colorectal adenomas, we do not know what to believe!
No one but the fibers
Containing all the published studies on the subject, Professor Goodlad6 tries to enlighten us. According to him, several factors may explain the conflicting results of recent years. First, the term "fiber" appears too general, there is not a single fiber but different kinds each with a different action in the colon. In addition to this oversimplification, the author stresses that sometimes studies are conducted around a high-fiber diet now on taking dietary supplements containing fibers. This confusion makes obsolete many results on the subject and emphasizes the need for new, more precise studies.
In conclusion, the author points out that a balanced diet, engaging in physical exercise and the fight against obesity is very important. Finally, in the context of the prevention of colon cancer, it recommends a diet rich in fiber, but from food, especially fruits and vegetables. These natural fibers are good for what they contain, but also for what they do not contain: fat and excess calories.
Good LuckTo All!!!
