Effects of Recording Food Intake Using Cell Phone Camera Pictures on Energy Intake and Food Choice.

Area of Science:

• Nutrition science
• Mobile health technology
• Behavioral science

Background:

• Rising obesity and poor dietary habits necessitate evidence-based interventions.
• Mobile phone cameras offer novel methods for dietary intake recording.
• Visualizing food intake via photography may enhance awareness of consumption patterns.

Purpose of the Study:

• To evaluate the impact of cell phone picture-based food recording on energy intake and food choices in college students.
• To assess the effectiveness and acceptability of this dietary self-monitoring technique.

Main Methods:

• A repeated measures crossover design was employed.
• Participants recorded food intake via memory recall and cell phone pictures over two 3-day periods.
• Focus groups gathered qualitative feedback on the method's usability and perceived benefits.

Main Results:

• Significantly higher intake of meat and vegetable servings was observed during the memory recall period compared to the cell phone picture period.
• Focus group participants reported positive attitudes towards using cell phone pictures for diet recording.
• An increased awareness of food selection and portion sizes was noted by participants.

Conclusions:

• Cell phone picture-based diet recording presents a practical, relevant, and accessible approach for self-monitoring dietary habits.
• Integrating this technique with nutrition education could further support dietary behavior change.
