What Are the Challenges in Nutritional Epidemiology?
Nutritional epidemiology faces several challenges:
Dietary Assessment: Accurate measurement of dietary intake is difficult. Self-reported data can be prone to errors and biases. Confounding Factors: Many factors, such as lifestyle and genetic predisposition, can confound the relationship between diet and health outcomes. Long Latency Periods: The effects of diet on health can take years to manifest, making long-term studies necessary.
