Using Food-Frequency Questionnaires for Calcium Intakes

An accurate knowledge of people's eating habits makes it possible to develop strategies to counteract bad habits and thereby reduce the risk factors for many chronic degenerative diseases. There are several methods that can be used to assess dietary intake and that provide valid data in large-scale population studies, but the food-frequency questionnaire (FFQ) has the advantage of being an inexpensive method to rapidly obtain data from a large number of subjects with a relatively low respondent burden. Therefore, the FFQ is a useful tool for assessing nutritional habits in a number of different types of study. There is no standard FFQ, each questionnaire should be judged for its ability to provide the information for which it is intended. Calcium is an essential nutrient for body health that plays a vital role in neuromuscular function, many enzyme-mediated processes, and blood clotting. For skeletal health, calcium is the most important nutrient throughout the lifespan, and assumes a critical role in the pathogenesis of osteoporosis.
