What can cause variations in nutritional needs among individuals?

• A. Only age and gender.
• B. Health status and economic status.
• C. Age, gender, activity level, and health status.
• D. Culture and tradition solely.

Answer: (C)

Nutritional needs can vary significantly among individuals due to a variety of factors, with age, gender, activity level, and health status being critical determinants.

Age influences nutritional requirements because different life stages—from childhood to elderly—have distinct growth, development, and maintenance needs. For instance, children and adolescents require more calories and nutrients to support growth, whereas older adults may need fewer calories but more of certain nutrients to maintain health.

Gender also plays a role in nutrient needs, primarily due to differences in body composition, hormonal influences, and metabolic rates. For example, women may have increased needs for certain nutrients during pregnancy and lactation, while men might require different ratios of macronutrients for muscle maintenance.

Activity level is another key factor. Physically active individuals typically have higher caloric and nutrient needs to support their energy expenditure and muscle recovery, compared to those who are sedentary.

Health status can dramatically impact nutritional requirements. For example, individuals with chronic illnesses may have heightened needs for certain vitamins or minerals to support healing, while others could have restrictions that diminish their nutrient intake.

Combining these factors allows for a more personalized approach to nutrition, ensuring that individuals meet their unique dietary needs effectively. This comprehensive understanding of individual differences is vital for effective nutrition
