Quinoa nutritional analysis: 14 g protein with a complete amino acid profile, iron, magnesium, gluten-free. Why quinoa is one of the best plant protein sources.

Quinoa (Latin: Chenopodium quinoa) is a pseudocereal that the Incas called the 'mother grain'. It is one of the few plant foods containing all 9 essential amino acids. NASA recognized quinoa as one of the most ideal foods for long-term space missions.

Quinoa is one of the few plant sources with a complete amino acid profile, including lysine, which is lacking in most grains. 100 g of quinoa provides 14 g of high biological value protein — more than any other grain.
Quinoa has 4.6 mg of iron per 100 g — more than beef. This is especially important for endurance athletes and women, who often lack iron. Better oxygen transport = better performance.
197 mg of magnesium per 100 g provides almost half the daily requirement. Magnesium is essential for energy (ATP) production, muscle contraction and relaxation, and nerve signal transmission. Cramps? You may be lacking magnesium.
Quinoa is safe for people with celiac disease, but unlike most gluten-free products, it is more nutritious, not less. This is a rare trait — a gluten-free product that surpasses wheat in nutritional value.
Always rinse quinoa before cooking! The surface contains saponins — natural compounds that cause bitterness. Rinse with cold water in a fine sieve for 30 seconds.
💡 Meal prep with quinoa: Cook 300 g of quinoa for Monday. Store in the refrigerator in an airtight container for 5 days. Use as a base for salads, a side dish with protein, or porridge for breakfast.
Quinoa has a better protein profile than most plant sources and can be an important part of vegetarian sports nutrition. However, quinoa alone cannot completely replace meat — it has less protein per 100 g (14 g vs 26–31 g in meat) and less leucine. Combine it with beans, tofu, nuts.
Due to saponins — a natural protective layer. Always rinse quinoa before cooking! Most quinoa in stores is already rinsed, but additional rinsing won't hurt.
Ratio 1:2 (quinoa:water). Bring to a boil, reduce heat, cook covered for 15 min. Turn off the heat and let stand for 5 min. Fluff with a fork. Perfect texture — when a white 'ring' (germ) is visible.
Consume 1.6–2.2 g/kg body weight per day for muscle growth and recovery. Distribute protein evenly across 3–5 meals.
The main energy source for intense training. 3–7 g/kg depending on the sport and intensity.
Healthy fats from nuts, fish, avocados — for hormone production and joint health. 0.8–1.2 g/kg per day.
Drink 30–40 ml of water per 1 kg of body weight. During training, additionally 500–1000 ml per hour with electrolytes.
