What It Is

Intake24 is an open-source, self-administered online 24-hour dietary recall system based on the multiple-pass 24-hour recall method. It is mainly used to collect information on an individual’s food and beverage intake from the previous day. Strictly speaking, it is not an education or course platform in the usual sense, but rather a research tool for nutrition, public health, and dietary survey work. The page indicates that the current version is aimed at Australia and provides access to a demo and videos.

Core Evaluation Dimensions

In terms of subject area, it relates to dietary assessment, nutrition surveys, and public health research rather than skills-training courses. Course-related elements such as teaching format, live or recorded classes, 1-on-1 instruction, and certification are not shown on the page. The system’s core capabilities include online 24-hour recall, an average completion time of about 20 minutes, a database of more than 2,500 foods, over 2,500 validated portion-size estimation images, automatic coding to nutrition data, and spreadsheet exports covering energy, macro- and micronutrients, and other data. Its search algorithm is highly tolerant of spelling mistakes, and it includes prompts for issues such as omitted drinks, low-energy reporting, and long gaps between eating occasions.

Pricing and Organizational Background

The page does not disclose commercial pricing, deployment fees, or subscription models; it only states that the system is significantly cheaper than interviewer-led recall methods. In terms of background, the system was originally developed by Newcastle University and funded by Food Standards Scotland. It was developed for people aged 11 to 24 and has also been field-tested among users aged 11 and above, including older adults. Validation studies show that Intake24 underestimates energy intake by about 1% on average, and that mean values for most nutrients differ from interviewer-led recalls by within 4%.

Pros and Cons

Its strengths are that it is open source, localizable, and supports automated data output, making it suitable for large-scale surveys. It also has a certain validation base. The code uses the Apache License, while the food database uses the Open Government License, which is helpful for secondary development by research institutions. Its limitations are that it is not a course product for individual learners and lacks learning paths, teacher interaction, and certificates. In addition, pricing, technical support levels, and deployment requirements are not specified, and the page does not confirm whether the Australian version can be adapted to a Chinese food database.

Who It Is For and Access from China

It is suitable for nutrition, public health, and epidemiology teams, as well as organizations that need to run dietary intake surveys. It is not suitable for learners looking for nutrition courses, certificate training, or one-on-one teaching. The page provides no information on access from China or payment methods, so these remain unknown. For projects in China, it is important to verify network accessibility, data compliance, Chinese-language interface support, and alternatives for a local food database.
