A 2005 editorial in *Cancer Epidemiology Biomarkers Prevention* raised a major alarm, suggesting that millions of research dollars spent on studies using food frequency questionnaires (FFQs) might be in vain due to inherent limitations. This perspective begs the question: Do food frequency questionnaires have too many limitations?

According to research published in the *Journal of the Academy of Nutrition and Dietetics*, the 24-hour recall method has demonstrated satisfactory validity for assessing nutrient intake at a population level. This established technique is a cornerstone of nutritional epidemiology, providing detailed, quantitative data on an individual's food and beverage consumption over the previous day.
