3. Amaranth provides necessary vitamins, minerals and fiber.
If you need to add more insoluble fiber to your diet, amaranth is a great starting point. But that’s not all: A serving of cooked amaranth grain (about half a cup) provides 14% of your daily iron needs. It’s also a good plant-based source of calcium, phosphorus, manganese, potassium, magnesium, and vitamins B2 and B6. Amaranth may also benefit your vision because of its high amounts of beta-carotene and lutein.
