Soy Products: A Complete Protein Source

Soy products like tofu, tempeh, edamame, and miso are complete proteins, providing all nine essential amino acids (EAAs). With a protein content of 1520% (tofu), soy is a versatile option for addressing nutrient deficiencies. Below, we detail the amino acid profile of tofu and its nutritional benefits.

Highly Digestible

Protein quality comparable to animal sources

Rich in Lysine

Supports collagen & immune function

Versatile

Tofu, tempeh, edamame, miso

Amino Acid Profile

Protein Content: 15-20% (tofu)

Essential Amino Acids
• Histidine: ~0.5 g/100 g (supports tissue repair and nerve function)
• Isoleucine: ~0.9 g/100 g (aids muscle repair and energy production)
• Leucine: ~1.41.6 g/100 g (promotes muscle growth and hormone production)
• Lysine: ~1.21.4 g/100 g (enhances calcium absorption and collagen formation)
• Methionine: ~0.20.3 g/100 g (supports liver function and antioxidants)
• Phenylalanine: ~0.80.9 g/100 g (precursor to neurotransmitters)
• Threonine: ~0.7 g/100 g (supports immune function and collagen production)
• Tryptophan: ~0.20.3 g/100 g (supports mood and sleep regulation)
• Valine: ~0.9 g/100 g (supports muscle repair and energy)

Non-Essential Amino Acids
• Alanine: ~0.8 g/100 g (energy metabolism)
• Arginine: ~1.4 g/100 g (blood flow and tissue repair)
• Aspartic Acid: ~2.0 g/100 g (energy and neurotransmitters)
• Cysteine: ~0.2 g/100 g (antioxidant support)
• Glutamic Acid: ~3.2 g/100 g (neurotransmitter and energy)
• Glycine: ~0.7 g/100 g (collagen and detoxification)
• Proline: ~0.9 g/100 g (collagen synthesis)
• Serine: ~0.9 g/100 g (immune function)
• Tyrosine: ~0.6 g/100 g (thyroid support)

Nutritional Benefits and Uses

High Digestibility: Soy’s protein is highly bioavailable, comparable to animal proteins.
Rich in Lysine: Supports collagen formation and immune health, ideal for plant-based diets.
Versatile: Tofu in stir-fries, tempeh in sandwiches, edamame as snacks, or miso in soups.
Additional Nutrients: Provides iron, calcium (in fortified tofu), and isoflavones for heart health.
Considerations: Potential allergen; choose non-GMO or organic soy to address consumer concerns.
