Research Question:
Observational studies suggest a link between fiber intake and the risk of getting type 2 diabetes, but the results are inconsistent. Therefore, this review article was carried out.
Eating fiber reduces the chances of getting diabetes type 2?
Study Design:
This overview article contained 17 prospective cohort studies with 488293 participants, of which 19033 people with diabetes type 2.
Results and conclusions:
The researchers found that eating total fibers, corn fiber, fruit fiber and insoluble fiber, the chance of getting type 2 diabetes significantly with respectively 19% [95% CI = 0.73-0.90], 23% [95% CI = 0.69-0.85], 6% [95% CI = 0.88-0.99] and 25% [95% CI = 0.63-0.89] reduced.
The researchers found a non-linear relationship between eating (total) fibers and getting diabetes type 2, with a non-significant reduced risk of 2% at 15 grams per day, a non-significant reduced risk of 3% at 20 grams per day, a significantly reduced risk of 11% at 25 grams per day, a significantly reduced risk of 24% at 30 grams per day and a significantly decreased risk of 34% at 35 grams per day.
The researchers found that every increase of 2 grams of corn fiber a day, the chance of getting type 2 diabetes significantly with 6% [RR = 0.94, 95% CI = 0.93-0.96] reduced.
Significant is, there is a link at a 95% reliability.
The researchers concluded that eating fiber (at least 25 grams a day) the chances of getting diabetes type 2 reduced. The reduced risk was non-linear.
