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.

Explore the essential amino acids needed for growth and maintenance and learn about different types of proteins: High Biological Value (HBV) and Low Biological Value (LBV). Understand the concept of complementary proteins and how they can provide complete nutrition. This quiz covers important dietary requirements across different life stages.
