Answer:
Biomarkers such as serum micronutrient levels are used in the field of nutritional epidemiology. Nutritional epidemiology is a subfield of epidemiology that focuses on the relationship between diet and health. Biomarkers are substances that can be measured in the body and that provide information about a person's health. Serum micronutrient levels can be used as biomarkers of fruit and vegetable intake because they are a reflection of the amount of fruits and vegetables that a person has eaten.
There are a number of advantages to using biomarkers to assess fruit and vegetable intake. First, biomarkers are more accurate than self-reported dietary intake. People often underestimate their fruit and vegetable intake, so biomarkers can provide a more accurate assessment of their diet. Second, biomarkers can be used to assess fruit and vegetable intake over time. This is important because fruit and vegetable intake is associated with a number of health outcomes, including a reduced risk of chronic diseases such as heart disease, stroke, and cancer.
Biomarkers such as serum micronutrient levels are a valuable tool for nutritional epidemiology. They can be used to assess fruit and vegetable intake more accurately than self-reported dietary intake, and they can be used to assess fruit and vegetable intake over time. This information can be used to develop interventions to improve fruit and vegetable intake and to reduce the risk of chronic diseases.
