Dietary surveys refer to a method used by researchers and health professionals to collect information about people's eating habits, food choices, and dietary patterns. This type of survey may be conducted through interviews or questionnaires that ask individuals about their consumption of specific food items, meal frequency, and other related factors. The data collected from these surveys can provide valuable insights into the nutritional status of a population, as well as help identify potential health risks associated with certain dietary habits. Dietary surveys are often used to inform public health policies, develop educational programs, and guide nutrition research.
