Whey vs Soy vs Yeast vs Pea vs Peanut — Protein Ranking (Stop Choosing Wrong) 🧪❌

Scientific Concepts / Discoveries / Nature Phenomena Mentioned

Protein supplement pricing trends

• Whey concentrates / “majority concentrate”-based blends
  • Rising cost range mentioned: ₹500–₹3000 per kg
• Whey isolates
  • Mentioned range: ₹4500–₹5000 per kg
• Expectation
  • Pricing is expected to continue increasing, which may push companies toward plant proteins.

Protein quality and absorption metrics (used to rank proteins)

• “PDCS”
  • Used as a benchmark score for protein quality/utilization (as referenced in the subtitles).
• Digestibility
  • How readily the protein is broken down and used.
• “DIA S / DICE”
  • A score related to protein utilization/efficiency (as referenced).
• Amino acid completeness
  • Complete proteins: contain all essential amino acids.
  • Incomplete / limiting profiles: lack one or more essential amino acids.
• Leucine content
  • Leucine is linked to muscle protein synthesis (MPS) signaling; higher leucine is portrayed as better.
• Absorption efficiency
  • Faster amino acids entering the bloodstream are described as producing a stronger muscle-building signal (whey is described as best).

Comparisons among protein sources

• Whey protein — #1 benchmark

  • Reasons cited:
    • Highest “PDCS”
    • Complete protein with a highly balanced/optimal amino acid profile
    • Absorption efficiency > 1 (as stated)
    • High leucine content (~10–12%)
    • Fast digestion
  • Supporting claim:
    • FAO “Digestibility Model” suggests animal proteins have higher absorption rates than plant proteins.

• Soy protein — #2

  • Reasons cited:
    • Complete amino acid profile
    • Lower absorption efficiency than whey
    • Lower leucine → weaker muscle-building signal than whey
  • Research claim mentioned:
    • Soy is the only complete plant protein, but has a lower “real absorption rate.”

• Yeast protein — #3

  • Reasons cited:
    • Complete amino acid profile
    • DICE ~0.8 (decent but not top)
    • Leucine similar to soy but lower than whey
    • In vitro (lab-based) studies: lower digestibility than other proteins
    • Human long-term data: described as limited

• Pea protein / Rice protein — #4

  • Reasons cited:
    • PDCS ~0.6–0.8
    • “Incomplete/limiting” amino acid profile
    • Anti-nutrients reduce absorption
    • Very low leucine
    • Consistently lower digestibility vs whey
  • Note:
    • Blending may improve results, but still doesn’t match whey.

• Peanut protein — #5 (last)

  • Reasons cited:
    • Incomplete protein: lysine low
    • Low PDCS (~0.5)
    • Poor digestibility
    • Nut protein quality described as consistently low

Practical decision factors

Protein choice may depend on:

• Vegan status
• Lactose intolerance
• Allergies
  • Example mentioned: soy allergy → maybe switch to yeast; peanut allergy → avoid peanut
• Budget
  • Low budget → pea/rice suggested

Methodology / Ranking Approach (as described in the video)

Proteins are ranked using a “scientific comparison table” based on:

• PDCS score (protein quality benchmark)
• Digestibility / absorption efficiency
• Whether the protein is complete
• Leucine content (MPS signaling)
• Evidence from research, including:
  • Claims about animal vs plant digestion/absorption (FAO model)
  • In vitro digestibility results for yeast
  • Notes on limited human long-term data for yeast
