Study Notes
Protein Sources and Requirements
- Essential Amino Acids (IAAs): Ten for children's growth and repair, eight for adult maintenance. These must be obtained from food, as the body cannot produce them.
- High Biological Value (HBV) Proteins: Contain all essential amino acids in sufficient quantities. Primarily found in animal sources (meat, cheese, fish, milk, eggs). Also, Soybeans.
- Low Biological Value (LBV) Proteins: Lack one or more essential amino acids. Primarily found in plant sources (cereals, pulses, some nuts, vegetables, quorn). Gelatin is an exception, being an animal source with LBV.
- Complementary Proteins: Combining LBV plant proteins (e.g., beans and rice) provides a complete protein source, as the lacking amino acids in one food are often present in the other. This combination doesn't need to be in the same meal.
- Protein Requirements: Essential for all, but needs increase during specific life stages like: rapid growth (babies, children, adolescents), pregnancy, and breastfeeding. Protein also maintains and repairs the body as well as promotes hair, nail, and skin growth.
