Whole-Grain Foods May Help Prevent Type 2 Diabetes
A new study
finds that a diet high in fiber from whole-grain foods may
help prevent type 2 diabetes in both men and women.
in Finland assessed the dietary habits of more than 2,200 men
and more than 2,000 women (age 40 to 69) who
have diabetes. Ten years later, 54 men and 102 women had
developed type 2 diabetes.
When the participants were divided
into four groups based on their consumption of whole-grain
foods, those with the
consumption were 35% less likely to have diabetes than
those with the lowest consumption. In addition, those consuming
the most fiber from cereal were 61% less likely to have
diabetes than those consuming the least, suggesting that
association between whole grains and diabetes is largely
due to cereal fiber.
The study does not prove that diets
high in whole-grain foods prevent diabetes, but it suggests
that people who
diets have some protective factors. The researchers offer
explanations. First, soluble fiber may slow the absorption
of carbohydrates and so reduce the demand for insulin.
fiber moves carbohydrates more quickly through the intestines,
leaving less time for the body to absorb the carbohydrates.
