When taking the image, participants need to include a fiducial marker, which acts as a reference of known dimension and markings.
The images are automatically analysed for characteristic features in food, such as colour, texture, and intensity, which are then used to identify a food.
Young adults typically consume a diet which is inconsistent with the dietary recommendations.
Yet little is known about the best approaches to improve dietary intakes and behaviours among this group.
Together the information from image analysis and volume estimation can be linked to a nutrient database to estimate energy and nutrients consumed.
The TADA system is currently being trialled in free-living populations but the full application with automatic image analysis is not yet available for public distribution.
‘Junk food’ or EDNP foods have been defined as any food (including beverages) high in fat, sugar and/or salt with little nutritional value or discretionary/non-core foods such as fast foods, sweetened breakfast cereals, confectionery or fizzy drinks .
Assessment of food intake in relation to dietary recommendations is necessary so that they are better informed on what constitutes a healthy diet consistent with dietary guidelines.The mobile phone application uses a camera to capture before and after images of food and beverages consumed.These images are automatically uploaded to a server for analysis using a Wi-Fi connection.Increasing fruit and vegetable consumption and limiting energy intake from total fats and sugars are dietary priorities to prevent chronic disease .Despite the evidence that in Australia young adults consume a diet inconsistent with the dietary recommendations, little is known about the best approaches to improve their dietary intakes and behaviours.This trial will test if applications running on mobile devices have potential to assess diet, provide tailored feedback and nutrition messages as an effective way of improving fruit and vegetable consumption and reducing energy-dense nutrient poor foods in young adults.
