Dietary Fiber for Diabetes

Dietary Fiber for Diabetes

Dietary fiber is linked to almost all aspects of diabetes and its complications. Increasing dietary fiber intake through food and sugar-free fiber supplements has been shown to positively impact the risk factors and complications associated with diabetes including heart disease, obesity, brain health and immune health.

  • Inadequate dietary fiber is linked to almost all aspects of diabetes and its complications
  • Most people do not eat enough dietary fiber
  • Increasing dietary fiber has been shown to positively impact the risk factors and complications associated with diabetes
  • Many popular fiber supplements contain more sugar that fiber, so picking the right one is important

Dietary Fiber and Diabetes1-4

  • People with diabetes have an increased risk of heart disease and high fiber diets are known to reduce cardiovascular risk5,6 
  • Increasing dietary fiber is known to have beneficial effects on cholesterol, triglycerides and blood glucose levels.7–9 
  • Long term use of low-glycemic index fiber-rich foods has been shown to improve blood glucose control and reduce the number of hypoglycemic events in people with Type-1 diabetes10 
  • Increasing fiber intake has been shown to lower levels of C-reactive protein (CRP), an important indicator of inflammation and increased cardiac risk, both of which are common complications of diabetes11,12

Increase Fiber Intake, Not Sugar Intake

Check nutritional labels of fiber supplements to compare fiber and sugar content. If there is more sugar than fiber, it is not appropriate for people with diabetes.
Some fiber supplements contain more sugar than fiber, making them inappropriate for people with diabetes

It's easy to find products in the grocery store that advertise their high fiber content - but don't be fooled. Many of those products contain unhealthy amounts of added sugars and relatively little fiber. They are essentially candy with a small amount of fiber added to help make marketing claims.

Some of the common culprits include:

  • Breakfast Cereals
  • Breads and pastries
  • Fiber / protein / meal replacement bars
  • Fiber supplements

Be sure to check the labels for added sugars to make sure you're getting the benefits of fiber without the downside of refined sugars.

Benefits of Proprietary Blend DigestiveHealth Prebiotic Fiber 

  • Unlike many fiber supplements, Proprietary Blend DigestiveHealth prebiotic fiber has a low-glycemic index and is free of sugars and artificial sweeteners that can contribute to metabolic imbalances including diabetes.13–15
  • Some prebiotic fibers like inulin from chicory root and fructooligosaccharides (FOS) break down into simple high-glycemic index sugars when heated or exposed to acidic foods like tomato sauce and orange juice - even your stomach acid can turn them into simple sugars!

Proprietary Blend DigestiveHealth uses non-GMO soluble vegetable fiber that has been shown to remain stable without breaking into simple sugars when heated or exposed to acidic foods, meaning that it keeps a low-glycemic index even when you cook with it.15

  • Uses a slow-digesting fiber like that in Proprietary Blend DigestiveHealth can remedy the gas and bloating commonly seen with equivalent doses of rapidly fermenting fibers like inulin or FOS15,16
  • Odorless, flavorless, and dissolves completely so it can be added to virtually any recipe – both foods and beverages – without altering the taste or texture 
  • Free of common allergens including gluten, eggs, soy, and dairy so can safely be used by people with food sensitivities
  • Helps promote healthy intestinal bacteria that help improve digestion, absorption of nutrients, immune health, and inflammatory conditions while reducing the risk of developing diabetes and obesity.3,4,17–19
  • The specific type of soluble prebiotic vegetable fiber used in Proprietary Blend DigestiveHealth has been shown to help maintain triglycerides, bad cholesterol, and blood sugars following a meal and help with reducing visceral fat.7–9 

Proprietary Blend DigestiveHealth makes it easy to boost you and your family’s daily fiber intake. Start incorporating it into your cooking, or simply mix it in with your favorite soft foods and beverages. This is a simple and cost-effective way to help keep you and your family healthy.
