Cereal Fiber May Lower Diabetes Risk
People who have diets rich in fiber--particularly cereal fiber--may have a lower risk of developing type 2 diabetes, according to new research published in the journal _Diabetologia. _
To conduct their study, the scientists split their research into two parts. The first was data from 12,403 patients with type-2 diabetes, from eight different European countries. The data came from the EPIC-InterAct study from Cambridge University in the U.K. which is the largest diabetes study in the world. The team split the data into four groups (lowest amount of fiber to highest) to examine the relationship between fiber--such as total fiber, and fiber from cereal, fruits and vegetables--and diabetes. After tracking the data across an 11-year span, and adjusting for other factors, they found that those in the high-fiber groups (26g per day) had an 18 percent less chance of developing diabetes, compared to the low-fiber group (19g per day). Additionally, fiber from cereal had the strongest connection to lowering diabetes risk, while fiber from fruit didn't seem to make a big difference.
Scientists then collected 41,000 cases of patient data from 18 other studies from US, Europe, Australia and Asia, and repeated their test with the new larger group. Similarly, they found that for each 10g increase of cereal fiber, risk of type 2 diabetes dropped by 25 percent, and for every 10g of overall fiber, risk was lowered by 9 percent.
Overall, the researchers believe that the consumption of cereal fiber doesn't directly affect diabetes risk, but that including it in your diet regularly can help you maintain a healthy weight, and that's what reduces diabetes risk.
