Previous findings had suggested a link between eating whole grains and other high fiber food with lower colorectal cancer risk but now a large review of 25 different studies has brought strong evidence to support the idea.
Theanlysis which included nearly 800,000 individuals showed that every 10 grams of daily intake of total dietary fiber and cereal fiber was associated with 10 percent lower colon cancer risk.
A team of UK and Dutch researchers added three servings including overall 90 grams of whole grains to the daily diet of participants and found that it decreased their risk of colorectal cancer by about 20 percent.
According to the report published in the British Medical Journal (BMJ), the most strong association was found when the fiber s came from whole grains and cereals while the evidence was weaker for the fiber coming from fruits, vegetables, and legumes.
Lower colorectal cancer risk is not the only benefit of consuming more fibers, the researchers added. Previous studies had found a range of other health benefits for eating fibers including lower rates of cardiovascular disease, type 2 diabetes, obesity, and possibly overall mortality.
Scientists emphasized that future investigations may explore and explain many of the specific mechanisms involved in the health benefits of whole grains in detail.
