Comparison of an Online Dietary Assessment Tool (the “Boden Food Plate”) With 24-Hour Dietary Recalls

We compared the “Boden Food Plate,” an online dietary assessment tool, with 24-hour recalls. Forty-two adults with body mass index of 25 kg/m2 or more completed 2 to 3 days' intake on the “Boden Food Plate” and 2 dietitian-administered 24-hour recalls. The mean differences between the 2 methods for energy, macronutrients, and micronutrients were predominantly not statistically significant. Moderate to high correlation was observed between the 2 methods, with the exception of protein and iron intakes. Bland-Altman plots for energy, carbohydrates, fat, and protein indicated wide limits of agreement between the 2 methods. The “Boden Food Plate” is comparable with 24-hour recall but with wide limits of agreement.
