If you think the words “whole grain” on your food label are a sure-fire way to choose healthy foods high in fiber, think again.

Recent research published in Nutrition Today shows most consumers mistake “whole grain” labeling to indicate food is a good source of dietary fiber—when, in fact, fiber content in whole-grain foods varies widely. High-fiber foods must contain at least 5 g or more per serving.

So what’s a health-conscious consumer to do? Look for both! Choose foods labeled “whole grain” that also have high fiber content to ensure you’re getting the full health benefits of fiber—including weight control and improved cardiovascular and gastrointestinal health.
