• Low Biological Value (LBV) Protein


  They are known as incomplete proteins and they lack more than one essential amino acids.
• Sources of LBV Protein

  • Almonds
  • Dhal
  • Barley
• Complementary Proteins


  They are formed by two biological value proteins that the body obtains all the essential amino acids.
• Sources of Complementary Proteins
