What Are The Challenges in Studying Diet and Disease?
Studying the relationship between diet and disease presents several challenges:
Dietary assessment: Accurately measuring what people eat is difficult. Self-reported dietary data can be biased or inaccurate. Complexity of diet: Diet consists of numerous foods and nutrients that can interact in complex ways, making it hard to isolate the effects of individual components. Long latency periods: Many diseases develop over many years, making it challenging to link dietary habits from the distant past to disease outcomes. Confounding factors: Other lifestyle factors, such as physical activity and smoking, can confound the relationship between diet and disease.
