What tool is used to compute the nutrient value of food during a nutrition survey?

The Food Composition Table is specifically designed to provide comprehensive information about the nutrient content of various food items. This tool is invaluable during a nutrition survey as it allows public health professionals to analyze and quantify the nutritional intake of individuals or populations based on the foods they consume. By using the Food Composition Table, practitioners can identify the amounts of proteins, carbohydrates, fats, vitamins, and minerals present in the foods surveyed, enabling accurate assessments of dietary habits and nutritional adequacy.

The other options, while related to nutrition in various ways, do not serve the same purpose. For instance, the RENI (Recommended Energy and Nutrient Intake) is focused on providing guidelines for daily nutrient intake rather than directly analyzing food content. The Food Exchange List is a dietary planning tool commonly used for managing dietary intake, particularly in the context of diabetes, rather than evaluating specific food nutrient values. "Your Guide to Good Nutrition" typically serves as an educational resource on general dietary guidelines rather than a quantitative analysis tool used during surveys. Therefore, the Food Composition Table stands out as the appropriate and precise tool for computing nutrient values in a nutrition survey context.
