Fiber May Reduce Insulin Production In Those At Risk For DiabetesEating high fiber foods such as fortified cereals and have been shown to help manage insulin production in men with high insulin levels. This suggests that fiber and foods containing fiber could be a simple and effective treatment for those at risk of developing type 2 diabetes due to various reasons. Managing insulin production, after all, is a main problem for those with diabetes so keeping it under control through your diet should be an easy call to make.
Insulin Production & Diabetes
High levels of insulin production is a sign of insulin resistance in the body. Insulin resistance is a precursor to type 2 diabetes. As increased insulin production and insulin resistance occurs, blood glucose levels increase as the glucose is not processed properly and thus the pancreas over-compensates and exacerbates the problem by producing more insulin, resulting in even higher levels of the hormone.
Fiber & Healthy Production of Insulin
A recent study led by Dr Thomas Wolever from the University of Toronto published in the journal Diabetes Care showed that consuming high-fiber cereal "reduced the rise in peak insulin compared with that seen after a low-fiber product." The team looked at the blood glucose levels and insulin production responses of 77 men after eating two different cereals each containing different amounts of fiber with all else being equal. In the end it was determined that the high fiber cereal caused a decreased rise in blood glucose levels and moderated insulin production whereas the low fiber cereal did not.
What made the study fairly interesting in my opinion is that the moderation of the blood glucose response was only noted in those who hyperinsulinemic and not on those who were control subjects. This seems to indicate that if you have trouble regulating blood sugar and keeping insulin production in check eating high-fiber cereals or anything containing high fiber is a must.
The authors of the insulin production study also noted that "further studies are needed to investigate whether cereal could play a role in the ongoing management of insulin resistance." That’s standard speak from the researchers on reversing insulin resistance with diet, but it’s hard to bet against the concept of eating more fiber to increase wellness if not to regulate or increase insulin production in the pancreas.
Buy Foods Which Promote Health & Longevity
Diabetes is one of the fastest growing diseases and regulating insulin production is a key action in it’s treatment. Even if you are not at risk for diabetes there’s no reason you should let this stop you from getting more fiber. Keep this in mind the next time you’re walking through the grocery store. Food does not just keep us from feeling hungry; buying insulin producing foods can help us live a longer and healthier life.
