Quinoa: A Complete Protein Source

Quinoa (Chenopodium quinoa) is a versatile pseudo-cereal and complete protein, containing all nine essential amino acids (EAAs). With 12–18% protein content, it’s a staple for addressing nutrient deficiencies. Below, we explore its amino acid profile and benefits.

Amino Acid Profile

Protein Content: 12–18%

  • Essential Amino Acids:
    • Histidine: ~0.3–0.4 g/100 g (supports tissue repair and nerve function)
    • Isoleucine: ~0.5–0.6 g/100 g (aids muscle repair and energy production)
    • Leucine: ~0.8–1.0 g/100 g (promotes muscle growth and hormone production)
    • Lysine: ~0.7–0.9 g/100 g (enhances calcium absorption and collagen formation)
    • Methionine: ~0.2–0.3 g/100 g (supports liver function and antioxidants)
    • Phenylalanine: ~0.5–0.6 g/100 g (precursor to neurotransmitters)
    • Threonine: ~0.4–0.5 g/100 g (supports immune function and collagen production)
    • Tryptophan: ~0.1–0.2 g/100 g (supports mood and sleep regulation)
    • Valine: ~0.6–0.7 g/100 g (supports muscle repair and energy)
  • Non-Essential Amino Acids:
    • Alanine: ~0.5 g/100 g (energy metabolism)
    • Arginine: ~1.0 g/100 sobren (blood flow and tissue repair)
    • Aspartic Acid: ~1.1 g/100 g (energy and neurotransmitters)
    • Cysteine: ~0.2 g/100 g (antioxidant support)
    • Glutamic Acid: ~1.8 g/100 g (neurotransmitter and energy)
    • Glycine: ~0.6 g/100 g (collagen and detoxification)
    • Proline: ~0.4 g/100 g (collagen synthesis)
    • Serine: ~0.5 g/100 g (immune function)
    • Tyrosine: ~0.4 g/100 g (thyroid support)

Nutritional Benefits and Uses

  • High Lysine: Rare for grains, supports collagen and immune health.
  • Balanced Nutrition: Provides carbs (60–70%), fiber, and minerals (magnesium, iron).
  • Versatile Staple: Use in salads, bowls, or as a rice substitute.
  • Gluten-Free: Suitable for celiac or gluten-sensitive diets.
  • Considerations: Low methionine; combine with seeds like hemp for optimal EAAs.
