Teff
Teff is a tiny ancient grain native to Ethiopia, rich in fiber, protein, and minerals, commonly ground into flour for porridge and flatbread. It has a relatively low glycemic index and contains all nine essential amino acids.
Also known as: Eragrostis tef, Teff grain, Ethiopian grain

Teff is a grain crop (Eragrostis tef) originating from the Ethiopian highlands, where it has been cultivated for millennia. The grain is exceptionally small—roughly the size of a poppy seed—making it labor-intensive to harvest by hand. Teff is most commonly ground into flour to make injera, a spongy Ethiopian flatbread, though it is also prepared as a whole-grain porridge, added to smoothies, or used in baked goods. It is naturally gluten-free and widely available in whole-grain and flour forms in health food stores and online retailers.
Raw teff contains approximately 13% protein by dry weight. Cooked teff provides a good amount of protein and fiber, along with meaningful amounts of magnesium, zinc, iron, and phosphorus. Teff contains all nine essential amino acids, though lysine levels are relatively modest, so it is best described as a near-complete plant protein rather than a fully complete one. The grain is digested relatively slowly due to its fiber and resistant starch content, which may support more stable blood glucose levels. Fermentation during traditional injera preparation can increase bioavailability of certain minerals, though this benefit is not present in unfermented teff flour.
Blood Sugar and Glycemic Response
Teff has a reported glycemic index in the range of approximately 55–74 depending on preparation method. While some preparations fall into the low-to-medium glycemic category, others, such as injera, can be high GI. Its fiber content and dense nutrient matrix slow carbohydrate absorption. Because portion control and overall meal composition remain important for blood glucose management, teff should be incorporated as part of balanced meals rather than consumed in isolation.
Tolerance and Usage Considerations
Teff is well tolerated by most people. Because it is gluten-free, it is suitable for those with celiac disease or gluten sensitivity. No established upper intake limits or common adverse effects are documented at typical dietary amounts. Whole teff grain can be difficult to digest in very large quantities due to its fiber content; gradual introduction and adequate hydration are recommended for those unaccustomed to high-fiber foods. Teff contains moderate levels of phytates, which can slightly reduce mineral bioavailability, but this is not a significant concern at normal consumption levels.
Frequently Asked Questions
Is teff gluten-free?
Yes, teff is naturally gluten-free and safe for people with celiac disease or gluten sensitivity. It is an ancient grain that does not contain the gluten proteins found in wheat, barley, or rye.
How much protein does teff contain?
Raw teff is approximately 13% protein by dry weight. Cooked teff is a good source of protein. Teff contains all nine essential amino acids, though it is best described as a near-complete plant protein since its lysine content is relatively modest compared to animal proteins.
Does teff spike blood sugar?
Teff has a glycemic index in the range of approximately 55–74 depending on preparation. While some preparations fall into the low-to-medium glycemic category, others, such as injera, can be high GI. Its fiber content contributes to a more moderate glycemic response in many forms, though overall meal composition also plays an important role.
Can teff cause digestive issues?
Teff is well tolerated by most people but is a good source of fiber. Those unaccustomed to high-fiber foods should introduce it gradually with adequate water intake to avoid digestive discomfort.
