Demographic Trends in Nutritional Needs and Preferences

Key Findings

• Vitamin D intake in Canada requires a multistaged strategy for food fortification to address diverse population needs and preferences.
• Micronutrient intake and adequacy vary significantly by race, ethnicity, and income levels, with lower-income groups having less access to dietary supplements.
• Dietary quality among emerging adults is influenced by demographic, socioeconomic, and health-related characteristics, as measured by the Healthy Eating Index.
• There are significant challenges in measuring dietary diversity, particularly in developing countries, due to conceptual and operational issues.

Practical Applications

• Fitness coaches should consider the socioeconomic background of clients when advising on dietary supplements, as access may be limited for lower-income individuals.
• Coaches can use the Healthy Eating Index to assess and improve dietary quality among young adult clients, tailoring advice to their specific demographic and health profiles.
• Incorporate strategies for increasing dietary diversity in coaching plans, particularly for clients from diverse cultural backgrounds, to ensure comprehensive nutrient intake.
