Exam Question and Protein Alternatives
Exam question: Explain the differences between high and low biological value proteins 6marks
Answer:
HBV proteins contain all essential amino acids that the body can't produce. Examples include meats, tofu, and fish. Without these, the chain of amino acids would be incomplete, and proteins couldn't be formed properly.
LBV proteins lack one or more essential amino acids. Examples include nuts, seeds, and cereals. To address this issue, protein complementation can be used by mixing LBV proteins e.g.,riceandpeas to obtain all essential amino acids.
Protein alternatives:
- Soya bean products tofu,miso,soyamilk
- Mycoprotein Quorn
Advantages of these alternatives:
- High HBV protein content
- High in fiber
- Low in fat
Disadvantages:
- Low in minerals
