Which condition is associated with diminished immune response?

Which condition is associated with diminished immune response?

• A. Excess carbohydrate intake
• B. Adequate protein intake
• C. Protein malnutrition
• D. High fiber diet

Answer: (C)

Protein is essential for the immune system because it provides the amino acids needed to make immune cells, antibodies, and signaling molecules like cytokines. When protein intake is chronically low, the body can’t sustain normal immune production, leading to weakened defenses. This shows up as smaller lymphoid organs (like the thymus), reduced numbers of immune cells, lower antibody levels, and a blunted inflammatory response, all contributing to a diminished ability to fight infections. Adequate protein supports robust immunity, while extreme imbalance from excess carbohydrates or a high-fiber diet doesn’t have the same direct, well-established impact on immune function as protein malnutrition.
