Assessment of Food Intake Using Both 3D Scanning Method and a Photographic Method

Assessment of Calories in the Diets Using 3D Scanning and a Photographic Method

This project aims to develop a new and more accurate method to assess energy intake in the diet by collaborating with Astravis company in Switzerland, integrating image recognition and intelligent applications, to improve the accuracy of energy assessment in the food, and to explore the application in dietary research.The researchers will recruit 200 volunteers.

Study Overview

• Status: Recruiting
• Conditions: Data Collection

Detailed Description

This study will provide food for the participants, and they will independently choose their preferred food for consumption according to their usual dietary habits. This study will take 3D scanning and photography of the food plates before and after eating to analyze the energy intake by each participant.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
BMI of the volunteers	The volunteers' BMI is chosen between normal and underweight for easy comparison.	This study will take about 1 year and a half to finish, starting from May 1 2025 to Dec 31 2026.
3D scanning of the foods chosen by volunteers using a Bodyscan3d smartphone application	The volunteers will be asked to choose 5 out of 20 dishes in a buffet and 3D scanning of the foods chosen by volunteers will be taken using a Bodyscan3d application.	This study will take about 1 year and a half to finish, starting from May 1 2025 to Dec 31 2026.
Weight and name of each food	The weight and name of the food selected by the volunteers will be systematically recorded using a digital electronic scale and food record form. This scale and food record form will be employed to ensure accurate measurements of each food item's mass that the volunteers consume throughout the study period and each food item they choose.	This study will take about 1 year and a half to finish, starting from May 1 2025 to Dec 31 2026.
Calories of the food chosen by the volunteers will be evaluated using the Hava smartphone application	We use another Hava application to evaluate the calories of the food selected by the volunteers and compare with the calories we calculated, with the smaller the difference, the better the Hava assessment.	This study will take about 1 year and a half to finish, starting from May 1 2025 to Dec 31 2026.
