What word should you look for when grocery shopping for a source of insoluble fiber?

The correct choice is bran, which is a key source of insoluble fiber. Insoluble fiber is important for digestive health as it adds bulk to the stool and helps food pass more quickly through the stomach and intestines. Bran, particularly wheat bran, is the outer layer of grains and is well-known for its high insoluble fiber content.

When grocery shopping, if you come across products labeled with bran, you can be confident that you are selecting a product that is rich in insoluble fiber. This is crucial for maintaining regular bowel movements and preventing digestive issues.

In contrast, pasta, rice, and bread can contain varying amounts of fiber, but they often have a different composition. Pasta and bread typically have more soluble fiber, especially if they are made from refined grains. Rice, particularly white rice, has very little fiber compared to whole grain options. Thus, while these items can contribute to your overall fiber intake, they are not as reliable a source of insoluble fiber as bran.
