What Are Some Challenges in Nutritional Epidemiology?
Researchers face several challenges in nutritional epidemiology:
Measurement errors: Accurate dietary assessment is difficult due to reliance on self-reported data. Confounding factors: Identifying and controlling for other variables that may influence health outcomes. Diverse populations: Accounting for variations in diet, genetics, and lifestyle across different groups. Long-term follow-up: The need for extended periods of observation to capture the development of chronic diseases.
