Key Points

Spelt: An ancient grain and a top source of protein, offering nearly 11 grams per cooked cup, plus excellent fiber and minerals.
Amaranth: A complete protein pseudocereal that is gluten-free and packed with iron and magnesium, making it great for porridges and thickening stews.
Teff: A tiny, gluten-free grain from Ethiopia rich in protein, calcium, and iron, often used for flatbreads and hot cereal.
Quinoa: A well-known pseudocereal and complete protein that cooks quickly and is versatile for salads, bowls, and side dishes.
Kamut: An ancient wheat variety boasting a buttery flavor and high protein content, suitable for soups, salads, and baking.
Wild Rice: Not true rice but the seed of a grass, it is gluten-free, high in protein, and full of fiber, with a hearty, nutty taste.
Incorporate Variety: Mixing these high-protein grains and pseudocereals provides a more complete range of amino acids and micronutrients for a well-rounded diet.

Top Contenders for High-Protein Grains

When searching for plant-based protein, several grains stand out for their superior nutritional profile. While protein content can vary by preparation and serving size, these grains consistently rank at the top.

Spelt: The Ancient Wheat Powerhouse

Spelt, a relative of modern wheat, is one of the most protein-dense grains available, with a cup of cooked spelt providing over 10 grams of protein. It is also an excellent source of dietary fiber, manganese, zinc, and iron. Its nutty, slightly sweet flavor makes it a versatile ingredient, perfect for grain bowls, salads, and soups. However, it is important to note that spelt contains gluten and is not suitable for those with celiac disease.

Amaranth: The Gluten-Free Complete Protein

Technically a pseudocereal and not a true grain, amaranth is a tiny seed with a big nutritional punch. A cooked cup offers around 9 grams of protein and, like quinoa, is considered a complete protein because it contains all nine essential amino acids. Amaranth is also an exceptional source of iron, magnesium, and manganese. When cooked, it has a porridge-like consistency, making it a great addition to cereals or as a thickener for stews.

Teff: The Ethiopian Staple

Teff, a minuscule, gluten-free grain, is a staple in Ethiopian cuisine and offers around 10 grams of protein per cooked cup. This grain is also notable for its high calcium and iron content. Its earthy flavor works well in porridges, baked goods, and traditional Ethiopian flatbread, injera.

Quinoa: The Popular Pseudocereal

Quinoa remains a popular choice for health enthusiasts due to its impressive nutritional profile. A cup of cooked quinoa contains over 8 grams of complete protein and is rich in fiber, iron, and magnesium. Its quick cooking time and mild, nutty taste make it an incredibly versatile alternative to rice or couscous.
