Fiber is plant roughage — the part of veggies, fruits, beans, grains, nuts and seeds that resists digestion. Now you might think why do we eat it when it’s eventually going to come out? Fiber makes you feel full. Fiber is made up of the indigestible parts or compounds of plants, which pass relatively unchanged through our stomach and intestines. Hence, it is important as Fiber helps clean out our digestive system and get rid of things (namely extra hormones, cholesterol, toxins and waste) that shouldn’t be there.
