Teff, or eragrostis tef, is native to Ethiopia and is the world’s tiniest grain. It is about the size of a poppy seed but packs a huge nutritional punch. It is full of calcium, protein, iron and is also a great source of fiber so you stay full and are able to regularly “take care of business.” Teff is also naturally gluten free and is a resistant starch. Resistant starches are not digested in the small intestine but, instead, processed by bacteria in your colon. These bacteria turn it into molecules that help maintain good gut health and balance blood sugar.
