Are sunflower seeds high in fiber?
Sunflower Seeds are a good source at 3 g per serving, ranking 7 of 21 nuts and seeds in the FiberUp database. Pairing it with a legume or whole grain gets a meal past 10 g.
Is the fiber in sunflower seeds soluble or insoluble?
About 17% of the fiber in sunflower seeds is soluble (0.5 g) and 83% is insoluble (2.5 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of sunflower seeds would reach a daily fiber goal?
It would take about 9 servings to reach 25 g (the adequate intake for adult women) and 13 servings to reach 38 g (adult men). Spreading fiber across several foods is easier and better for gut bacteria diversity.
