Which of the following is a common sign of nutrient deficiencies?

• A. Weight gain
• B. Increased energy
• C. Fatigue
• D. Improved immunity

Answer: (C)

Fatigue is a common sign of nutrient deficiencies because many vitamins and minerals play crucial roles in energy metabolism and overall bodily functions. For instance, deficiencies in iron can lead to anemia, which often presents as fatigue due to reduced oxygen transport in the blood. Similarly, a lack of B vitamins can impair energy production at the cellular level, leading to tiredness and lethargy.

On the other hand, weight gain, increased energy, and improved immunity are typically not associated with nutrient deficiencies. Weight gain often indicates an excess of caloric intake or lifestyle factors rather than deficiencies. Increased energy levels usually reflect adequate nutrition and health rather than a lack of nutrients. Improved immunity generally indicates a well-nourished state, as proper nutrition supports the immune system, while deficiencies would likely weaken immune responses. Thus, fatigue stands out as a clear indicator of potential nutrient deficits.
