What factor may cause aversions to protein-rich foods in terminal illness?

• A. Tumors may cause aversions to protein-rich foods
• B. Hydration status influences texture preference
• C. Physical activity level
• D. Vitamin supplementation increases protein taste

Answer: (A)

A key idea is that taste and smell changes caused by the cancer itself can lead to aversions to protein-rich foods in advanced illness. When a tumor drives systemic inflammation and metabolic disruption, inflammatory mediators can alter gustatory and olfactory function. That can make protein-dense foods—like meats, dairy, and eggs—taste unusually strong, metallic, or off in a way that is unappealing. The result is a reduced desire for protein-heavy items, contributing to poorer protein intake.

Other factors don’t explain this specific aversion as well. Hydration status can influence how textures are perceived, but it doesn’t typically create a targeted dislike for protein-rich foods. Physical activity level isn’t a primary driver of protein aversion in terminal illness, and vitamin supplementation doesn’t inherently increase the taste or palatability of protein foods.
