Ethiopian Marathoners Have Been Running on This Grain for Centuries. America Is Just Now Catching On.
Every few years, the wellness world discovers something that the rest of the world has known forever. Quinoa came out of the Andes. Turmeric out of South Asia. Now comes teff — the tiny, ancient grain that has fueled the greatest distance runners on the planet for thousands of years and is quietly making its way into protein bars, gluten-free bakeries, and health-conscious pantries across the United States.
If you haven’t heard of it yet, you will.
The Grain Behind the World’s Best Runners
Teff is an ancient crop likely domesticated more than 6,000 years ago in Ethiopia, the primary center of the plant’s diversity. Its name is thought to come from the Amharic word meaning “lost” — a nod to just how small the seeds are. At roughly 1/100th the size of a wheat kernel, it’s the smallest grain used by humans.
That small size belies an outsized legacy. The Whole Grains Council estimates that Ethiopians get about two-thirds of their daily protein from teff, and the grain provides a livelihood for nearly 43% of the country’s farmers. Legendary Ethiopian distance runners Haile Gebrselassie and Kenenisa Bekele — two of the greatest marathon and long-distance athletes in history — have both named teff as a central pillar of their training diet.
The connection to elite performance isn’t coincidental. Teff is made up of 20 to 40% resistant starch and sits low on the glycemic index, releasing energy slowly and steadily rather than spiking blood sugar — the kind of sustained fuel that endurance athletes depend on. Ethiopian distance runners have long credited teff with providing the stamina needed to compete at the highest levels, and its slow-release carbohydrates make it particularly well-suited for people managing blood sugar as well.
What Actually Is Teff?
Teff is a staple crop in Ethiopia and Eritrea where it forms the base of injera, a fermented flatbread central to East African cuisine. Unlike many modern grains, teff has remained largely unchanged by selective breeding — making it a genuinely ancient grain in the truest sense.
Injera is simultaneously the food, the plate, and the utensil. The spongy, slightly tangy flatbread is laid flat, topped with spiced stews and vegetables, and torn off to scoop up every bite. It’s one of the oldest continuous food traditions in human history, and it starts with teff.
Teff has a nutty flavor and works well in porridges, grain bowls, and as a gluten-free flour for baking everything from traditional injera to pancakes and baked goods. It comes in two main varieties — brown and ivory — with brown carrying a more pronounced earthy flavor and ivory tasting milder and slightly sweet.
As a crop, teff uses roughly ten times less water than wheat to grow, thrives in both drought and waterlogged conditions, and can be cultivated at sea level or at elevations up to 3,000 meters. In an era of climate volatility and increasing scrutiny around agricultural sustainability, that resilience is starting to matter to food companies planning their supply chains.
A Nutrition Profile Built for the Modern Consumer
Teff’s rise in Western markets isn’t being driven by marketing alone. The nutritional case is legitimate and, in several key areas, genuinely exceptional.
Teff is a complete protein, containing all nine essential amino acids — one of the very few plant-based sources that can make that claim. A 100-gram serving delivers 7.2 mg of iron, 180 mg of calcium, 184 mg of magnesium, and 427 mg of potassium.
The iron number is worth pausing on. A 100-gram serving of teff flour provides 37% of the recommended daily value for iron, compared to just 5% from the same amount of wheat flour. For women, vegetarians, and anyone prone to iron-deficiency anemia, that difference is significant. Elite endurance athletes have noted that teff’s iron content may help offset iron losses that occur from the breakdown of red blood cells during intense training — a problem common among distance runners.
A single cup of teff also delivers 7.1 grams of fiber, 9.8 grams of protein, and meaningful amounts of lysine — an amino acid notably scarce in most other grains that helps the body absorb calcium, produce collagen, and regulate hormones.
It’s also gluten-free, which has made it attractive to the growing segment of consumers either diagnosed with celiac disease or simply moving away from wheat.
The Market Is Waking Up
The global teff market generated roughly $2 billion in 2026 and is projected to reach $3.9 billion by 2035, growing at a compound annual rate of 8.2%. Demand among health-conscious consumers climbed 30% between 2021 and 2025, and ready-to-eat teff products expanded their shelf presence by 25% across North American and European supermarkets during that same window.
North America is currently the fastest-growing regional market for teff products, led by teff flour in gluten-free baking, whole grain teff in porridge and grain bowls, and increasingly, teff-based protein and energy bars targeting active consumers who want a cleaner ingredient story.
Established brands like Bob’s Red Mill have helped normalize teff on American shelves, while a growing field of specialized brands is pushing innovation into snacks, beverages, and other formats that move well beyond traditional uses.
A Story Worth Knowing Before You Buy
There’s one chapter of teff’s history that doesn’t get enough attention in wellness media. In 2003, a Dutch company filed a patent on teff flour processing — effectively blocking Ethiopia and Eritrea from selling teff-based products to European markets despite the grain being indigenous to those nations. Ethiopia fought back legally, and after a years-long battle, the patent was annulled and teff ownership was returned to its origin countries.
As teff goes global and Western brands build businesses around it, where the grain comes from — and who benefits from its commercialization — remains an open and important question.
The grain itself is extraordinary. It’s been extraordinary for six thousand years. The rest of the world is simply catching up.
