A high-fiber diet may reduce one’s risk of colorectal cancer. A review of research by British and Dutch physicians looked at data from nearly 2 million cases.
Those who had a higher daily intake of total dietary fiber and cereal fiber had a 10 percent reduced risk of colorectal cancer. And the results scale, so that with each 10 gram per day increase in intake of total dietary fiber and cereal fiber, there was an extra 10 percent reduction in risk of colorectal cancer.
While this particular study did not find evidence to show a link between fruit or vegetable fiber and colorectal cancer risk, a previous study showed that high levels of fruit and vegetable consumption were associated with a lower risk for colorectal cancer.
“In summary, our meta-analysis suggests that a high intake of dietary fiber, particularly from cereal and whole grains, is associated with a reduced risk of colorectal cancer,” the researchers said.
Moreover, a high fiber diet can also reduce the risk of heart disease, obesity, type 2 diabetes, and other grave illnesses.
“This study highlights the importance of a diet rich in fiber,” said Dr. Anthony Starpoli, a gastroenterologist at Lenox Hill Hospital in New York City. “We know that soluble is most helpful in improving colon transit times. As the contents of the colon move at a better rate, there is thought to be less toxic exposure to the interior of the colon thereby reducing risk of developing colon cancer,” he explained.
Colorectal cancer is one of the most common cancers in the world. There are 1.2 million new cases diagnosed each year.
