Study Notes
High Biological Value Proteins
- Animal-based proteins (e.g., meat, fish, eggs, dairy) are considered high biological value sources because they contain all essential amino acids in sufficient amounts.
- These proteins are easily absorbed and utilized by the body, making them ideal for growth and maintenance.
Complete Protein Sources
- Complete proteins include all nine essential amino acids necessary for human health.
- Foods such as quinoa, soy, and animal products provide complete proteins that meet the body's needs effectively.
Protein Deficiency with Adequate Calories
- Protein-energy malnutrition occurs when protein intake is inadequate despite sufficient total caloric intake.
- This condition can lead to muscle wasting and a weakened immune response, as the body lacks the necessary building blocks for tissue repair.
Low Biological Value Proteins
- Plant-based proteins (e.g., beans, lentils, nuts, grains) are typically classified as low biological value due to often lacking one or more essential amino acids.
- Although beneficial, these sources require careful combination to achieve a complete amino acid profile.
Combined Nutritional Deficiency
- Marasmus is a condition characterized by inadequate protein and caloric intake, leading to severe weight loss and malnutrition.
- Symptoms include extreme thinness, fatigue, and complications from a compromised immune system.
