16. Flaxseed: 0.6-1.2 of soluble fiber per serving

Flaxseeds, also called linseeds, are tiny brown, yellow, or golden seeds.
They contain many nutrients and are a great way to improve the nutritional content of your smoothies, bread, cereals, or energy balls.
One tablespoon of flax seeds can add an extra 3.5 grams of fiber and 2 grams of protein to your breakfast. They are one of the vegan sources of DHA, which has multiple benefits, especially for pregnant women.
You can soak your flaxseeds overnight. When the soluble fiber combines with water, it forms a gel that can aid in digestion.
