[IP] Re: Effects of fiber for preggers

Fiber Lowers Insulin Needs of Gestational Diabetics  

Bulking up on dietary fiber may help pregnant women with type 1 diabetes
control potentially dangerous fluctuations in their blood sugar, new study
findings suggest. 

According to the report in the March issue of the Journal of the American
Dietetic Association, diabetic women who consumed the most dietary fiber
during their second and third trimesters needed to inject themselves with
less insulin. Specifically, women who consumed about 20 grams of fiber
daily needed 16% to 18% less insulin than those who consumed only about 8
grams of fiber daily, regardless of weight and the duration and severity
of their disease, findings show. 

The results suggest that boosting intake of fiber-rich foods such as
fruits, vegetables, oatmeal and bran cereal can help pregnant women with
type 1 diabetes to reduce their reliance on insulin and stabilize their
blood sugar.  Fiber can also help to reduce the risk of hypo and
hyperglycemic blood sugars. 

Knowing that diets rich in fiber may reduce insulin requirements will
allow individuals to make appropriate adjustments in their insulin dose if
they change the fiber content of their diet.  

Hyperglycemia occurs when sugar (glucose) in the blood rises to levels
that over the long term can cause nerve damage, kidney disease and
blindness. In pregnant women, hyperglycemia can lead to miscarriage,
premature delivery and malformations of the baby.
It is not clear how fiber affects insulin sensitivity, but researchers
suggests that it may increase secretion of important proteins involved in
the metabolism of glucose (sugar). Fiber-rich diets have also been shown
to lower the risk of other diseases such as cancer, heart disease and type
2 diabetes, which occurs when cells fail to respond to insulin. Current
recommendations are to consume 25 to 35 grams of fiber daily.
