Which dietary assessment method is implemented via an interview format to uncover detailed consumption habits?

The method implemented via an interview format to uncover detailed consumption habits is the food recall. This approach typically involves a trained interviewer who engages with the individual to discuss their eating habits, often recalling what they consumed over a specific period, such as the past 24 hours or a week. The interviewer asks detailed questions about the types and amounts of food consumed, preparation methods, and other relevant factors influencing dietary intake. This method provides valuable qualitative data, capturing the nuances of a person's eating behaviors.

The food log is typically a self-reported tool where individuals record their food intake on their own over a set period, and while it can provide detailed information, it lacks the interactive element of an interview. The food frequency questionnaire is designed to assess consumption patterns over a longer timeframe, such as months or years, and is generally a structured survey rather than a conversational approach. Food screeners are brief instruments that focus on specific food groups or nutrients but do not typically delve deeply into overall dietary habits through an interview format. Therefore, food recall stands out as the method that best fits the criteria of being conducted via an interview to reveal detailed consumption habits.
