voedselfrequentieenquête

A voedselfrequentieenquête, often translated as a food frequency questionnaire (FFQ), is a dietary assessment tool used in research and public health to collect information about an individual's usual food and beverage intake over a specified period, typically the past year. It typically consists of a list of food items and beverages, with corresponding response categories indicating the frequency of consumption (e.g., daily, weekly, monthly) and sometimes portion sizes. The primary purpose of an FFQ is to estimate the habitual dietary intake of a population or individual. This information is crucial for studying the relationship between diet and health outcomes, such as chronic diseases like cardiovascular disease or certain cancers. FFQs are designed to be relatively quick and inexpensive to administer compared to other dietary assessment methods like 24-hour recalls or diet diaries. However, their accuracy can be influenced by a person's ability to recall their usual intake and the comprehensiveness of the food list provided. FFQs are widely used in large-scale epidemiological studies due to their efficiency in gathering dietary data from many participants. The data collected can then be analyzed to identify dietary patterns, nutrient intakes, and potential dietary risk factors.
