Dietary assessment tools are methods used to evaluate an individual's food and nutrient intake. These tools can include food diaries, 24-hour dietary recalls, and food frequency questionnaires. They help researchers and health professionals understand eating patterns and identify nutritional deficiencies or excesses. These assessments can be conducted through interviews, surveys, or self-reported records. By analyzing the data collected, professionals can provide personalized dietary recommendations and track changes over time, ultimately promoting better health and well-being.
