Is wheat a major dietary source of soluble fiber?

Wheat is not considered a major dietary source of soluble fiber; rather, it primarily contains insoluble fiber, particularly in whole grain forms. Soluble fiber is more abundant in foods like oats, barley, fruits, and legumes. While wheat does contribute some soluble fiber, its overall contribution is relatively low compared to these other sources. Therefore, for those looking to increase their soluble fiber intake, it's better to focus on these alternative foods.
