Corn Bran

Acceptable Keto IngredientWhat is Corn Bran?

Corn bran is the isolated exterior bran portion of corn, or maize, kernels. It is sold as an ingredient that can increase fiber content, bulk a food while contributing few digestible carbohydrate calories, and impart corn flavor in snack foods. Corn bran is also inherent to whole-grain corn and corn flour.


Corn Bran is primarily comprised of insoluble fiber. Corn bran is likely from GMO corn unless otherwise specified.

Corn Bran can also be made soluble

Soluble corn fiber, also referred to as resistant maltodextrin, is a type of dietary fiber made from cornstarch.

It’s produced using enzymatic hydrolysis, a process that involves breaking the chemical bonds of a molecule using enzymes.

Soluble corn fiber is typically used to thicken processed foods like cereals, baked goods, dairy products, protein bars, and salad dressings.

It’s also used in place of sugar as a sweetener due to its low glycemic index, which measures the extent to which a food affects your blood sugar levels

Because it doesn’t spike your blood sugar levels, it’s often used as a sugar substitute in low carb, keto-friendly products to help those following the ketogenic diet remain in the metabolic state of ketosis.

Along with being lower in calories and sugar than many other sweeteners, soluble corn fiber is rich in soluble fiber. This type of fiber absorbs water in the digestive tract to form a thick, gel-like consistency

Soluble fiber has been tied to several health benefits and may help support digestive regularity, decrease cholesterol and blood sugar levels, and promote weight loss.

Keto Status?



Neither soluble nor insoluble corn bran affect blood glucose. You may still want to check you glucose on the soluble, but studies have shown it doesn’t impact glucose levels.

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly
